RE: [Wrapper-user] How Does One... Remotely Restart a JVM

[Sal I. <sal...@sy...>]

thanks for the slack =)

back to your COM request problem.

I suggest you look at a thread dump to see if there is any part of your
program generating the COM requests:
1. run "wrapper -c wrapper.conf"
2. wait for the the program to enter a point in which you believe COM
requests are being performed
3. issue a ctrl-break

this will dump all the threads and their stack-traces.  you should
immediately be able to recognize any piece of code that indeed is making COM
requests.

however i can guess why the wrapper would *indirectly* generate com
requests:
1. the wrapper spawns a JVM
2. whether the wrapper uses ShellExecute (or WinExec), the call is always
proxied through ShellExecute
3. ShellExecute is not much more than utility function that simply wraps the
explorer COM interface to actually spawn the process
so that would explain the COM request.  but that is the only request i might
(if at all) expect to see.

Sal,

My apologies, my initial google search for JMX and DCOM shows up a
number of references.  I should have read them more closely.  The DCOM
reference, although in the same paragraph refered to other Sun
extension.

Back to the drawing board on why the wrapper generates COM requests.

Re: [Wrapper-user] Re: .bat equivalent of {start|stop|console|dump}

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

Mike,
Thanks for all the work you put into this and sorry for the slow response.
Here are my thoughts on this. I want to keep the existing batch files around
to give the users options. But personally, I think I will start using
your new
script. It looks great.

I am planning to add the new batch file as src/bin/AppCommand.bat.in
I am not totally happy with the name. Do you have any other ideas.

I don't really see any reason to put in the deprecated code as this will be
a new script. I know you were planning to replace the old script, so it
would
have been valid.

I also removed the code to create the logs directory. Its location will
depend on the configuration in the wrapper.conf file so it can't be hard
coded into the batch file. There has been a feature request to create the
batch file if it does not exist for a while, so I'll try to get that
implemented
in a cross platform way for the next release.

The batch file that I committed, with the above changes can be found at
the end of this mail. Let me know if you have any other suggestions. From
my testing so far, it looks great though. Good work.

Cheers,
Leif

[Wrapper-user] Re: Environment variables and console out and err output

[Geetha <ge...@ho...>]

Leif,

1. The first piece of set commands executed in a batch file, creates a =
unique file name to be used for logging purposes. The current date and =
time is taken and the special characters like / - : . and space are =
replaced and then used. This is not critical if the wrapper doesnt =
support this.

2. If I can redirect the console err and out output to different files, =
that would be great. This is critical since we need to monitor the =
system and debug any issues using the files. Would be glad if we could =
get this feature.=20

Thanks

=20
 I'll plead ignorant to this.  What are you expecting those various =
commands
 to do?  The only kind of variable expansion that the wrapper currently =
knows
 how to do is to expand an environment variable with the exact name =
between
 the '%' characters.   So it is going through each of your commands and=20
 looking
 for the specified environment variable.  When a variable can not be=20
 found, the
 Wrapper leaves the string as is.
=20
 So in this case, the last thing it does is look for an environment=20
 variable called
 "TS: =3D" which does not exist, so the TS variable gets the final =
string=20
 unmodified.
=20
 If you could explain what you are expecting to have happen here, and=20
 point me
 to some online docs describing the functionality, this may be something =

 could be
 a feature in a future release.  I am a bit curious.

 Currently this is not possible with the Wrapper.  It takes all output=20
 from the
 JVM, err and out and merges them into a single output stream.  out =
messages
 are logged at level INFO and err at level ERROR.

 As things are implemented right now, it would be difficult to get this=20

RE: [Wrapper-user] How Does One... Remotely Restart a JVM

[Sal I. <sal...@sy...>]

no.

1. download the jmx libraries from here
http://java.sun.com/products/JavaManagement/download.html

2. put these 2 files from the above download in your classpath
jmxri.jar
jmxtools.jar

3. convert the attached sample code to fit somewhere in your system.

4. point a browser to the jmx-console:
http://localhost:8082

5. Click on
Adaptor | protocol=Wrapper

6. Click restart

7. learn jmx from the best book: JMX Managing J2EE with Java Management
Extensions by Lindfors and Fleury

8. Next time, before you post, go to www.google.com, enter type "jmx", press
"Google Search", click on the first link that comes up & you'll find out
what jmx is (or at least that it's not COM)

RE: [Wrapper-user] How Does One... Remotely Restart a JVM

[Sal I. <sal...@sy...>]

we embedded the sun jmx server into our app & restart the service through
the wrapper jmx interface.
that's also how we issue thread dumps when running as a service.

Here's the situation:
I have a process that the wrapper runs as a service, but the service is on
another box.  I also do not have permission to restart the service.  In
cases where I have a patch to push out on the server, I have to wait for the
admin on the box to restart my service (as to reload the JVM and to load my
changes).

This might be correct in a production environment, but our development
environment is the same (I have to wait for someone else to restart the
service).  This gets a bit annoying (on the admin's side to), so here is my
question:
-Is there a way to remotely call "something" to restart the JVM on demand?

I have read that there is a WrapperManager that has a restart() method, but
how can that be called?  Would I have to have another service running that
has the sole purpose of restarting JVMs?

(This is on an NT 2000 box, and there is no chance to give me permission to
start/stop services on their boxes).

Thanks for any assistance.

So, I finished writing up a possible new App.cmd.in file.

@echo off
setlocal
rem
rem Find the application home.
rem
rem %~dp0 is name of current script under NT
set _APP_HOME=%~dp0
rem : operator works similar to make : operator
set _APP_HOME=%_APP_HOME:\bin\=%
set _WRAPPER_EXE=%_APP_HOME%\bin\Wrapper.exe

rem Find the requested command.
for /F %%v in ('echo %1^|findstr "^console$ ^start$ ^stop$ ^restart$
^install$ ^remove"') do call :exec set COMMAND=%%v

if "%COMMAND%" == "" (
  echo WARNING: Defaulting to running in console mode is deprecated. 1>&2
  set COMMAND=console
) else (
  shift
)

rem
rem Find the wrapper.conf
rem
:conf
set _WRAPPER_CONF="%~f1"
if not %_WRAPPER_CONF%=="" goto startup
set _WRAPPER_CONF="%_APP_HOME%\conf\wrapper.conf"

rem
rem Run the application.
rem At runtime, the current directory will be that of Wrapper.exe
rem
if not exist "%_APP_HOME%\logs" mkdir "%_APP_HOME%\logs"
call :%COMMAND%
if errorlevel 1 pause
goto :eof

:console
echo on
"%_WRAPPER_EXE%" -c %_WRAPPER_CONF%
goto :eof

:start
"%_WRAPPER_EXE%" -t %_WRAPPER_CONF%
goto :eof

:stop
"%_WRAPPER_EXE%" -p %_WRAPPER_CONF%
goto :eof

:install
"%_WRAPPER_EXE%" -i %_WRAPPER_CONF%
goto :eof

:remove
"%_WRAPPER_EXE%" -r %_WRAPPER_CONF%
goto :eof

:restart
call :stop
call :start
goto :eof

:exec
%*
goto :eof


Since the old App.bat.in used NT specific features in the main line anyway,
and since no one complained about it not working on 9x, I made the
assumption that no one is actually using Wrapper in a non-NT environment.

Therefore, I decided to it completely NT specific.

Unfortunately I don't have an NT4.0 handy, so I hope it still works on
that.  I don't think I used any 2K specific features.

I renamed the file from .bat to .cmd to reflect the NT specific nature of
the file.

I used setlocal to avoid having to undef envvars at the end of the script.

It now supports console|start|stop|restart|install|remove, so it's now very
similar to the Unix script.  Note that the Unix script still supports the
dump command, and the NT script supports install and remove.  Regarding
dump via NT service, I think the another thread addresses that issue and
may give room for thought.

With this script, the extra install/uninstall scripts are no longer
necessary.

I'm still undecided about remove versus uninstall for the command.
Actually no reason it can't be both.

The Unix script can stop one started via console; the NT script cannot.

The Unix script currently does not handle taking a second parameter to use
as a config file.  I think that if the NT one does, then the Unix one
should be similarly enhanced.

Still not sure about the whole deprecated message.  No feed back from the
list on that design point.  I think both platforms should function
similarly, and if the Unix script requires a command, then the NT one
should.

Enjoy!

I'll plead ignorant to this.  What are you expecting those various commands
to do?  The only kind of variable expansion that the wrapper currently knows
how to do is to expand an environment variable with the exact name between
the '%' characters.   So it is going through each of your commands and 
looking
for the specified environment variable.  When a variable can not be 
found, the
Wrapper leaves the string as is.

So in this case, the last thing it does is look for an environment 
variable called
"TS: =" which does not exist, so the TS variable gets the final string 
unmodified.

If you could explain what you are expecting to have happen here, and 
point me
to some online docs describing the functionality, this may be something 
could be
a feature in a future release.  I am a bit curious.

Currently this is not possible with the Wrapper.  It takes all output 
from the
JVM, err and out and merges them into a single output stream.  out messages
are logged at level INFO and err at level ERROR.

As things are implemented right now, it would be difficult to get this 
working
without breaking things compatibility wise for existing users.  I have 
one idea,
but I'll have to look into a bit.  At the best, it would be a little bit 
kludgey to
configure however. :-/

Re: [Wrapper-user] ctrl-break event on windows

That is commented out because it is not needed.  If that call is made 
then two stack traces would actually be dumped.  When CTRL-BREAK is 
pressed, both the Java and Wrapper processes get the signal.  I had not 
known that when I first implemented the feature.  I should really just 
remove it completely.

> I know one can call requestDumpJVMState() via the JMX

There is no way to directly send a CTRL-BREAK signal to an NT service.
(without using a third party program).    The Wrapper does provide a few 
ways
to work around it though.  The first is to use JMX, the method that you 
already
found.  The second is to instantiate the WrapperActionServer class and 
connect
via telnet to request a thread dump.  (You can see an example of this by 
looking
at the TestWrapper app source code or the javadocs)  The third is to call
WrapperManager.requestThreadDump() method directly from within your
application.

The WrapperActionServer is probably the easiest to get working as it 
just requires
a few lines of isolated code that can really exist pretty much anywhere 
in your
program.

If you have any other ideas, they may make good features for a future 
version.

Cheers,
Leif

[Wrapper-user] ctrl-break event on windows

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

When a wrapper on windows is not being run in console mode is
there a way to send a ctrl-break event to it?
If so, then why is the call to the method requestDumpJVMState()
in the file wrapper_win.c commented out in the method
wrapperConsoleHandler(..)?

I know one can call requestDumpJVMState() via the JMX
interface. I am interested in knowing if there is any other
way.

Thanks.

[Wrapper-user] Environment variables and console out and err output

[Geetha <ge...@ho...>]

Hi,

I just downloaded the Java Service Wrapper and I find it very useful.=20

I am facing two problems with the wrapper.=20

1. I have a need to create a unique file name for which i use the =
following commands in a batch file

set TS=3D%date%%time%
set TS=3D%TS:/=3D%
set TS=3D%TS:-=3D%
set TS=3D%TS:.=3D%
set TS=3D%TS::=3D%
set TS=3D%TS: =3D%

But when I put this in the wrapper.conf file in the specified format =
(set.TS format), TS evaluates in the end to %TS: =3D%.

2. Command line execution of my java program looks like
    java xyz1>test.out 2>test.err

    How do i specify this in the wrapper.conf file? Which property =
should be set to send the console out and err to the respective files?

Thanks
Geetha

RE: [Wrapper-user] Sockets and desktop

[ender w. <end...@ya...>]

In short:
I wrote a java program that listens to a Server Socket
and when receives a message on the socket
it prints it on the screen in a Frame.
The program works fine when I test it in the Wrapper 
console. 

Next, I tried adding a shortcut of the .bat file
frok the bin dir to the my startup folder.
When I log on the wrapper console appears, and it
says: 
//////////////////////////////////////////
wrapper  | --> Wrapper Started as Console
wrapper  | Launching a JVM...
jvm 1    | Wrapper (Version 3.0.5)
jvm 1    |
////////////////////////////////////////

but my program does not start.
If I look at the log I actually see that there is no
entry for the current time, ie for the user logon
time.

Basically I would like to know if I am using the
wrapper improperly, and if I am, how do I make my
program start automatically short of making an exe and
placing it in the startup?

[Wrapper-user] Jetty using win32 wrapper.

[Greg W. <gr...@mo...>]

I've just checked in changes to the 4.2 & 5.0 branches to change
from the custom win32 service to use the wrapper from
   http://wrapper.tanukisoftware.org

It was simple to use and is working fine for me - so thanks
to the tanukisoftware folks.

I'd appreciate testing of this from real win32 users before the
next releases.  The wrapper is in extra/win32 and I have included
a simple readme.

Hmmmm.... Does anyone use wrapper in a non-NT, but Win32 environment?

In looking at the App.bat.in, I see all code paths goes to this line:

:conf
set _WRAPPER_CONF="%~f1"

But I thought the ~f stuff was NT only.  Am I mistaken?

Just realized I may have to target any enhancements that I do to Win98 and
company, which could be annoying.

[Wrapper-user] .bat equivalent of {start|stop|console|dump}

[<da...@ix...>]

The newer Wrapper binaries, with the -t|-p support to start|stop NT
services is great (actually solved a problem for us last night).

However, having to take a config file option is a bit of a nuissance.
Especially since we already have the config file set up in the .bat file.

So, has there been any thought given to enhancing the .bat file to allow
{start|stop|console} to work the same as it does with the Unix script?

Right now the Unix and NT scripts behave differently.  The Unix script only
takes a single action parameter, while the NT script only takes a single
configuration file parameter.

I'd really like to propose that they come closer to performing similarly.

I think it'd be fairly easy to enhance both to take 2 parameters, the first
being one of {start|stop|console} and the optional second being a config
file.

I'm not sure what to do about dump on the NT side.  Help?

Anyway, I know this would be a big change for the NT script side, but, do
many people actually use the feature of the .bat file taking a config file
as a parm?  Would such a change break many people?

What about if, for a while, on the NT side, if the first param is not one
of {start|stop|console|dump} that a warning is issued, and the param is
used as a config file.  Then some later release, the {start|stop|console}
becomes mandatory?

Internally I will probably be making these changes anyway, but if the
Wrapper community has any thoughts on an approach they would accept, I'd be
willing to design towards that end.

You should be able to start your application when the user logs on by adding
it to the users startup folder in windows. You should be able to identify
the user via the system properties. Should work the way you want it to.

It  would be very nice to write an small program that
gets launched AUTOMATICALLY at user logon.(then this
application will communicate with the service that
collects messages and tell it to print the messages to
screen to screen)Is there a way(In Java)?

RE: [Wrapper-user] Regarding the service

[Sal I. <sal...@sy...>]

i've been using it since 98/99 to perform nightly/weekendly builds.

don't remember having any problems with it.

yeah -- i don't know why there are so many other schedulers out there
either -- i've even seen some that sell for money and don't even have as
many options as "at" .

also note that there are some schedulers on sourceforge.  i remember there
is a cross-platform scheduler that supports cron expressions.

you suggested the option to schedule the recurring job within the app.
The java Timer is not the best choice because it can't schedule events at a
time-of-day without some extra programming...
but fortunately there is "quartz", a java based scheduler that supports cron
expressions, simple recurring jobs, persistence, app-server integration.
and the best part: it is hosted on sourceforge.

RE: [Wrapper-user] Regarding the service

[Sal I. <sal...@sy...>]

i've always used "at", the windows scheduler.  run "at" from a command
prompt.
i believe on some windows installations it is not installed automatically
(just add it from the windows cd).
with this you can schedule recurring jobs, like a daily .bat (or wrapper -c
wrapper.conf) at a given time.
with this you can also schedule jobs on system events like startup/shutdown.

the "at" scheduler also has a UI. to get to the windows scheduler on my xp
box i click on this:
Start | Programs | Accessories | System Tools | Scheduled Tasks

also, last time i used a win98 box i found that it has a very similar
scheduler to "at", but not quite like it.
i ended up using it to simulate services by scheduling "wrapper -c
wrapper.conf" on system startup.

UNIX has cron jobs, but what exists on Windows.  I had actually looked
for something a
while back and was only able to locate a few overpriced commercial
solutions.   I ended
up having the Java program running 24x7, but with its main thread in a
wait state until the
time that the actual job needed to run.

Doing a google search on "Windows Scheduler" turns up several options
now.  A couple
have free versions as well.

I install my app as a NT service according the instruction of Method 1 in
Integration Methods.  It works. 

I stop the service and then re-start it by Services panel in Windows'
Control setting. Then I use the IE browser to access the app, I get a white
page, the error message in Jboss's log is Unable to compile class for JSP.

The app works fine when it is not installed as a service. I think I might
not configure the wrapper properly.

Could any one point out what's wrong with the configuration? Thanks.


The Environemnt is:
         Windows 2000 Professional SP3.
         Jboss-3.0.4_Tomcat-4.1.12
         j2sdk1.4.2_01
        Java Service Wrapper 3.0.5

Tthe following is the part of the wrapper.conf:

# Java Application
