wrapper-user — User issues for Wrapper. (Support questions, etc.)

Re: SV: SV: [Wrapper-user] Access network directories from NT service!

[Leif M. <le...@ta...>]

Saw your note on
http://forum.java.sun.com/thread.jsp?thread=373769&forum=4&message=1589244
No answers their other than it looks like it is possible.  Someone else was
even using the Wrapper.

The following is taken from the documentation on setting up Apache under 
windows.
The same should apply to your application with the Wrapper.  Please 
verify that
everything below is true for your account:
http://httpd.apache.org/docs/win_service.html


    User Account for Apache Service to Run As (NT/2000)

When Apache is first installed as a service (e.g. with the -i option) it 
will run as user "System" (the LocalSystem account). There should be few 
issues if all resources for the web server reside on the local system, 
but it has broad security privileges to affect the local machine!

    LocalSystem is a very privileged account locally, so you shouldn't
    run any shareware applications there. However, it has no network
    privileges and cannot leave the machine via any NT-secured
    mechanism, including file system, named pipes, DCOM, or secure RPC. 

NEVER grant network privileges to the SYSTEM account! Create a new user 
account instead, grant the appropriate privileges to that user, and use 
the 'Log On As:' option. Select the Start Menu -> Settings -> Control 
Panel -> Services -> apache service ... and click the "Startup" button 
to access this setting.

    A service that runs in the context of the LocalSystem account
    inherits the security context of the SCM. It is not associated with
    any logged-on user account and does not have credentials (domain
    name, user name, and password) to be used for verification. 

The SYSTEM account has no privileges to the network, so shared pages or 
a shared installation of Apache is invisible to the service. If you 
intend to use any network resources, the following steps should help:

    * Select Apache from the Control Panel's Service dialog and click
      Startup.
    * Verify that the service account is correct. You may wish to create
      an account for your Apache services.
    * Retype the password and password confirmation.
    * Go to User Manager for Domains.
    * Click on Policies from the title bar menu, and select User Rights.
    * Select the option for Advanced User Rights.
    * In the drop-down list, verify that the following rights have been
      granted to the selected account:
          o Act as part of the operating system
          o Back up files and directories
          o Log on as a service
          o Restore files and directories
    * Confirm that the selected account is a member of the Users group.
    * Confirm the selected account has access to all document and script
      directories (minimally read and browse access).
    * Confirm the selected account has read/write/delete access to the
      Apache logs directory!

If you allow the account to log in as a user, then you can log in 
yourself and test that the account has the privileges to execute the 
scripts, read the web pages, and that you can start Apache in a console 
window. If this works, and you have followed the steps above, Apache 
should execute as a service with no problems.

Cheers,
Leif

SV: SV: [Wrapper-user] Access network directories from NT service!

[Suo A. <And...@sw...>]

Hi Leif,
indeed, both wrapper and java.exe are running as the user I specified in =
conf. I'll try to set even more generous priviliges on the mapped drive =
to see if that has something to do with it.

Suo,
    If the same settings are working on your Win2k box, that makes me

SV: [Wrapper-user] Access network directories from NT service!

Thank you David, very useful application!=20
It actually shows that my service actually runs as the correct user! =
So... Maybe this is more of a java problem than a wrapper problem. I =
can't understand, though, why I am able to run in console mode but not =
as a service???

Suo,
Most people have gotten things working setting up an account.

A few things for you to check.
When you set the wrapper.ntservice.account and =
wrapper.ntservice.password
properties, id you uninstall and then reinstall the service.  This is=20
important or
the changes will not take effect.  (This is probable ok because you said =
you
verified the settings in the control panel.)

You say that the service is started, it is not running as the correct =
user?
How are you verifying this?   If there was a problem with the user then
the service would not start.   Under XP, you can see the user that a
service is running as by opening the Task Manager and enabling the
User Name column.  Most services run as SERVICE.  Most likely the
user is the one that is specified in your wrapper.ntservice.account
property.

If both of the above are true, then what exactly are you trying to do?
Is the network drive mapped to a local drive.  Ie R:/ or something or
are you accessing the network drive directly?  //machine/dir
If it is the later, try the first?  Just an idea, not sure it will make =
a
difference.

I only have access to 2000 and XP servers.  So I am unable to test NT
directly.  Do you have the ability to test on an XP or 2000 server?  =
There
is nothing I am doing that is widows-version specific, but who knows...

Re: [Wrapper-user] Wrapper stopping immediately

[Leif M. <le...@ta...>]

Hannu,
     It looks like you got everything setup correctly.  But the first 
argument
to the WrapperSimpleApp which specifies your main class is commented
out:
#wrapper.app.parameter.1=com.myApp.Main

    Also, I noticed that you are attempting to run as an NT service before.
I would strongly suggest getting things working in console mode before
attempting to install as a service.  It is much easier to work out problems
there as the output is visible in the console.

    I was able to work out what was happening because the
WrapperSimpleApp kicked out a clear message :-)  But the output
you sent me was from the log file, while the debug output was enabled
for the console.  Because of the way the output is triggered in the JVM,
this still makes the debug level output from the JVM visible, but no debug
output is visible from the Wrapper.  Try setting the 
wrapper.logfile.loglevel
to DEBUG and you will see a big difference in the output.  If you have any
future problems.  That is the debug output that I need to see to be able
to answer most questions.

    Let me know if you have any other problems getting set up.

Cheers,
Leif

Re: [Wrapper-user] Wrapper's current working directory

[Leif M. <le...@ta...>]

Anthony,

Early versions of the Wrapper did not used to set the current directory.
But the problem was that this made it very difficult to use relative paths
when working with the Wrapper.

Here is the problem:
If you first cd into a C:\myapp\bin directory and then run the Wrapper
then your current directory will be C:\myapp\bin and a reference to the
wrapper configuration file of ..\conf\wrapper.conf will work correctly.

But if your current directory is C:\myapp, and you launch the Wrapper
using a reference like bin\Myapp.bat then the above reference to the
conf file will fail as the ..\conf\wrapper.conf reference would resolve to
C:\conf\wrapper.conf, which is not correct.

To make things worse, when you install the wrapper as an NT service,
the current working directory will be C:\Windows\service32.

For this reason, you pretty much had to use absolute paths with earlier
versions of the Wrapper.  This unfortunately made it more difficult to
install software that used the Wrapper as the installer would have to go
through and set all of the absolute paths in the application at install 
time.

This is a common problem to all Windows, UNIX and other applications
and it would have been Ok, to force users to follow that standard.

But I found it annoying and wanted to fix it.  The easiest install 
program in
my book is one where you just unzip an archive file unto the directory of
your choice and have everything work!   Many applications, work this way
no problem but you have to run the application from a specific location
otherwise the relative paths all fail to resolve.

Originally, I wanted to have a configurable working directory in the
wrapper.conf file.  But there was a chicken and the egg problem.  You
need to be able to locate the wrapper.conf file before it can be loaded.
And to do that, you have to have a fixed starting point.   So I decided to
just have the Wrapper binary always force its working directory to be the
same as its location.

One option that I considered was to have the Wrapper behave as it does
now with respect to locating the wrapper.conf file, but then once it was
loaded change over to using a working directory configured in the conf file.
Bu that seemed like it would just get confusing for users without actually
giving any new functionality.   The problem there is that you can define
properties from the command line as well.  And paths in those properties
would be using a different base location than that used to locate the
wrapper.conf file.  For example:
Wrapper.exe -c ../conf/wrapper.conf 
wrapper.java.additional.1=-Dconf.file=conf/wrapper.conf
In the end I decided that this is one area where it would be best to limit
flexibility and just stick to forcing the location of the working directory.

For any decision I could have made, there would always be someone
who wanted to do something slightly different .  But this functionality is
the most flexible in my opinion.   It will support any application directory
structure that a user may want.   The scripts that ship with the wrapper
assume a directory structure where the Wrapper binary is located in the
bin directory, but there is nothing stopping the user from modifying the
scripts so that the Wrapper binary can be located elsewhere.  You just
have to follow the rule that all relative paths are relative to its new
location.

The UNIX side works slightly differently than the Windows platform in
that the current directory is set by the shell scripts rather than the 
binary
so in that way, they are a little more flexible.

If you create an environment variable in your wrapper.conf file with the
following value, you can then use that throughout the rest of the
config file to set all your other paths.
set.APP_HOME=../
wrapper.java.classpath.1=%APP_HOME%/lib/wrapper.jar

I think this is a lot less cluttered however:
wrapper.java.classpath.1=../lib/wrapper.jar

Hope this explanation helps.  Let me know if you have any suggestions on
improving how this works and I'll give them some thought.

Cheers,
Leif

There have been some improvements with timeout handling since 2.0.9.
Let me know the results with 3.0.2. Also, if you still have the problem then
please enable debug output to the logfile and then send me the area of the

log is
not very large then a full run is best. Usually I can nail down the exact

RE: [Wrapper-user] Wrapper's current working directory

[Palmer, D. <Dav...@ph...>]

This is what we do... we use
getClass().getResourceAsStream("foo.properties");
to load our properties file from the classpath, therefor we don't have to
worry about the actual locations of said files.

Dunno if this would work in  your situation, but it works out nicely for us.

I hope this helps

[Wrapper-user] Wrapper's current working directory

[Anthony F. <ant...@co...>]

First off, I must say this is one of the nicest Java service wrappers I have 
yet to use. It's flexibility and ease-of-use are unmatched! Kudos and thanks 
to Leif and the Wrapper team for making it available.

I think I may be missing something with configuration that I'm hoping someone 
has some suggestions for.

My standard practice has always been to write config files for my Java 
applications such that paths are relative to the "home" directory of the 
application. I also like to put executables (including Wrapper) in a "bin" 
directory. I know Wrapper is designed to always use the executable directory 
as the working directory and that relative paths can be used in wrapper.conf 
which is great because I can count on it.

My problem is that all of my non-wrapper.conf config files also need to be 
"aware" of the location of the executable and specify relative paths with a 
'../' prefix. The solution I've come up with is to add a "app.home" system 
property that gets used as the base to all relative paths throughout my 
application. This is a little cumbersome though since this needs to be done 
everywhere throughout the application. Is it possible to set the Java 
process's notion of the current working directory to this "home" directory or 
am I missing something else entirely?

Thanks for the help,
-Tony

Arun,
    What version of the Wrapper are you using?  Newer versions of the
Wrapper are able to detect that the CPU is at 100%.  Rather than timing
out and restarting the JVM, you will get a message like the following:

jvm 1    | JVM Process has not received any CPU time for 11798 seconds.
Extending timeouts.
wrapper  | Wrapper Process has not received any CPU time for 11800 seconds.
Extending timeouts.

    The case above was when I had suspended my system for a few hours.
The Wrapper was able to recover without any problems.  The warning message
is just that, a warning.   If another process takes up 100% of the CPU you
may see one or both of the above messages.  But hopefully it would be for
a period of time much shorter than the 3 hours above. :-)

    Were you seeing timeouts and JVM restarts or had you just noticed the
note in Troubleshooting guide?  I'll take a look at that entry and bring it
up
to date.

If another process is taking 100% of CPU, then there is no

CPU left for the JVM. The wrapper has no way of knowing that 

the reason the JVM has not pinged it is that the JVM is being 

starved of processor power. So, it makes the assumption that 

the JVM has hung.



The only way to avoid this is to not let other processes

on unix you could use "nice" to achieve this.

Suo,
    If the same settings are working on your Win2k box, that makes me
wonder if it is a problem with NT. I'm not sure if there are any differences
in the way NT handles account privileges.

    Could you give the program that David posted a try and verify that both
the Wrapper and JVM processes are both running as the intended user?
Most likely they are but it would be nice to confirm.

If both of the above are true, then what exactly are you trying to do?

=C4mne: Re: [Wrapper-user] Access network directories from NT service!


Suo,
Most people have gotten things working setting up an account.

A few things for you to check.
When you set the wrapper.ntservice.account and =
wrapper.ntservice.password
properties, id you uninstall and then reinstall the service.  This is=20
important or
the changes will not take effect.  (This is probable ok because you said =
you
verified the settings in the control panel.)

You say that the service is started, it is not running as the correct =
user?
How are you verifying this?   If there was a problem with the user then
the service would not start.   Under XP, you can see the user that a
service is running as by opening the Task Manager and enabling the
User Name column.  Most services run as SERVICE.  Most likely the
user is the one that is specified in your wrapper.ntservice.account
property.

If both of the above are true, then what exactly are you trying to do?
Is the network drive mapped to a local drive.  Ie R:/ or something or
are you accessing the network drive directly?  //machine/dir
If it is the later, try the first?  Just an idea, not sure it will make =
a
difference.

I only have access to 2000 and XP servers.  So I am unable to test NT
directly.  Do you have the ability to test on an XP or 2000 server?  =
There
is nothing I am doing that is widows-version specific, but who knows...

Cheers,
Leif

[Wrapper-user] Sub-java process being killed

[Richard E. <rem...@ed...>]

On windows I have the wrapper launching a Java process which
in turn launches (forks) a child java process. When the
user logs out the top level java process remains but the
inner child java process dies (and the higher level java process
detects this death and then kills itself). How can I
launch a child java process so that it will not die when a
CTRL_LOGOFF_EVENT is generated by windows?

Re: [Wrapper-user] Checking if service is alive

[<San...@DM...>]

I have test code below with the default test application and works fine=
.

Then I think there is something wrong in my code.

Now I know that there is possible pinging a service.

Thanks a lot.

There is nothing specific to the Wrapper that should be causing any
problems with the creation of sockets.  Can you answer a few questions?=


1) What platform / version of java are using?

2) What version of the Wrapper?

3) What is the exception you are getting?  (full stack trace)  Your cod=
e
does not display the stack trace.  I would modify it to look for one or=

more
specific exception rather than any exception as that code will mask
unrelated problems such as NullPointerExceptions etc.  If your p_host
variable was null for example you would get a message: "not responding"=


4) Is the code below running in a JVM controlled by the Wrapper,
or is the remote machine controlled by the JVM?

The only socket related difference between running with and without the=

Wrapper is the socket that is being allocated to communicate between
the JVM and the Wrapper.  It is configured using the wrapper.port
property in the wrapper.conf file.

[Wrapper-user] Checking if service is alive

[<San...@DM...>]

I have a service that launch a java app, sometimes this app could crash,
then the service goes down.

I have another java service that check if some services are alive. This
service runs code below to check services status:

      private boolean ping(String p_host, String p_port)
      {
            int count = 0;
            int portInt = Integer.parseInt(p_port);

            m_log.log(m_sCabeceraLogs,"Pinging "+ p_port+ " ...");

            while (count < 10) {
                  try {
                        Socket s1 = new Socket(p_host, portInt);
                        s1.close();
                        m_log.log(m_sCabeceraLogs,p_port+ " is running!");
                        break;
                  } catch (Exception e) {
                        m_log.log(m_sCabeceraLogs,p_port+ " not responding
.. retrying");
                        count++;
                  }
                  try {
                        Thread.currentThread().sleep(1000);
                  } catch (Exception e) {};
            }

            if (count == 10) {
                  return false;
            }else
            {
                  return true;
            }
      }

This code works fine this other services, but with services that uses
wrapper, sentence "Socket s1 = new Socket(p_host, portInt);" throws a
exception.

How can I tell wrapper that accepts this calls?

Re: [Wrapper-user] Problem with getting a service up

[Leif M. <le...@ta...>]

Most likely the problem is that you have not integrated with the Wrapper
correctly.  That message normally is displayed when the WrapperManager
class has not been initialized correctly.

Please go back and reread the integration options:
http://wrapper.tanukisoftware.org/doc/english/integrate.html

Most likely, the first integration method, using the WrapperSimpleApp helper
class will work for you:
http://wrapper.tanukisoftware.org/doc/english/integrate-simple-win.html

As a side note, to enable debug output in the wrapper.  you need to set
the log level of either the console or log file output
http://wrapper.tanukisoftware.org/doc/english/props-logging.html

[Sue E. <sue...@ic...>]

Appologies, I didn't read far enough down the existing e-mails (or the
documentation). It still doesn't work properly but I've got over the first
hump.  Sue

-----Original Message-----

Subject: Java Service Wrapper will not start my program


Windows 2000:

I have a java program which works fine on its own but won't work properly
with the wrapper, either as a console or service.

The program has a main method which starts two new daemon threads. One
thread runs many timer tasks, the other waits for incoming snmp traps on
port 162. The main method then sleeps for a few seconds in an infinite loop.

Running as a console, the program starts OK, creates the new threads and
then sleeps OK (I've got lots of logging so I know this is happening). The
problem is that after some seconds I get the following messages

wrapper  | Startup failed: Timed out waiting for signal from JVM.
wrapper  | Java Virtual Machine did not exit on request, terminated
wrapper  | JVM was only running for 31 seconds leading to a failed restart
count of 1

It then restarts and the whole process is repeated. If I do CNTL+C I get
this

wrapper  | CTRL-C trapped.  Shutting down.
wrapper  | wrapperStopProcess(0) called.
wrapper  | Sending stop signal to JVM
wrapper  | Shutdown failed: Timed out waiting for signal from JVM.
wrapper  | Java Virtual Machine did not exit on request, terminated
wrapper  | <-- Wrapper Stopped

There is almost nothing else running on my system - task manager shows the
system idle process using 95%+ of CPU.

It appears that the wrapper is unable to communicate with my JVM even though
it has started it successfully. I assume I have done something stupid but
can anyone tell me what?

[Wrapper-user] Java Service Wrapper will not start my program

[Sue E. <sue...@ic...>]

Windows 2000:

I have a java program which works fine on its own but won't work properly
with the wrapper, either as a console or service.

The program has a main method which starts two new daemon threads. One
thread runs many timer tasks, the other waits for incoming snmp traps on
port 162. The main method then sleeps for a few seconds in an infinite loop.

Running as a console, the program starts OK, creates the new threads and
then sleeps OK (I've got lots of logging so I know this is happening). The
problem is that after some seconds I get the following messages

wrapper  | Startup failed: Timed out waiting for signal from JVM.
wrapper  | Java Virtual Machine did not exit on request, terminated
wrapper  | JVM was only running for 31 seconds leading to a failed restart
count of 1

It then restarts and the whole process is repeated. If I do CNTL+C I get
this

wrapper  | CTRL-C trapped.  Shutting down.
wrapper  | wrapperStopProcess(0) called.
wrapper  | Sending stop signal to JVM
wrapper  | Shutdown failed: Timed out waiting for signal from JVM.
wrapper  | Java Virtual Machine did not exit on request, terminated
wrapper  | <-- Wrapper Stopped

There is almost nothing else running on my system - task manager shows the
system idle process using 95%+ of CPU.

It appears that the wrapper is unable to communicate with my JVM even though
it has started it successfully. I assume I have done something stupid but
can anyone tell me what?
