[Wrapper-user] Invoking another Java service from another Java service wrapper

[Chris K. <chr...@en...>]

Is there a way of programmatically invoking a Java service from another
Java service.
What I'm looking for is to invoke a Java service without use of explicit
configuration files. I could supply this as a
list of properties instead?
 
Thanks for any suggestions in advance.

Hello Leif,
Thank You very much for Your quick answer. After configuration
changes You recommended to me wapper works fine.
It is very useful program and save me a lot of troubles with my java=20

Re: [Wrapper-user] TestWrapper problem, please help

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

Eelco,
The "ReportEvent failed errno(1502)" messages that you are seeing are being
caused because your system EventLog is full.  This is a known problem 
that has
been fixed in the next release.  To get rid of these messages, open up 
your Event
Log viewer and clear the log.  Most likely other applications will be having
problems as well.

You should really set your wrapper.syslog.loglevel property to a lower 
log level.
 From the number of messages, I assume that you have it set to DEBUG.  That
will fill up your Event Log very quickly.  I would suggest using the 
logfile or
console to view debug log output.  Usually a value like ERROR, or NONE are
good values for the syslog.

Now on to your questions.

The message says that the java command can not be executed.  From the 
Windows
API, error 193 = "is not a valid Win32 application."  Please verify that 
the path to
c:\dev\jdk140\bin\java is actually a Java.exe.   I improved this error 
message as well
so it will now give a human readable error message no matter what the 
problem is.

<snip>
 From this output, it looks like the Wrapper is working correctly.  You 
are seeing
lots of "ReportEvent" messages due to your EventLog being full, but 
otherwise
it looks ok.

As the message says, this is because in order to build the Wrapper on 
Windows
platforms, you need to load the Wrapper project into MSVC and build the
Wrapper.dll and Wrapper.exe targets manually.  At some point, I will try to
automate this a little more.  The Unix platforms build entirely from Ant.

Re: [Wrapper-user] If I start my application JVM restarts

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

Mirek,
I see your problem.  You have the following in your config file:
---
# Java Additional Parameters
wrapper.java.additional.1=jtapiApp.Main

# Application parameters.  Add parameters as needed starting from 1
#wrapper.app.parameter.1=jtapiApp.Main
---

The wrapper.java.additional.n properties are used to pass arguments to 
the JVM
itself.  Is what you really want to be doing is pass the jtapiApp.Main 
class name
as the first argument to the WrapperSimpleApp main method.  This is done 
using
the wrapper.app.parameter properties.   You had the correct value commented
out in your conf file, so you were close.

You can see this in your log output.  The JVM is being launched with the 
following
parameters:
---
java jtapiApp.Main -Xms5m -Xmx64m -Djava.library.path=../lib
 -classpath ../lib/wrapper.jar:../lib/wrappertest.jar
 -Dwrapper.key=hJEaoVKN6ELBE6dI -Dwrapper.port=1786
 -Dwrapper.debug=TRUE -Dwrapper.cpu.timeout=10 -Dwrapper.jvmid=1
org.tanukisoftware.wrapper.WrapperSimpleApp
---
As things are, all of the parameters meant for the JVM are being passed 
to your
class's main method.  The reason things are timing out is that the
WrapperManager class is never being loaded and initialized.  The
WrapperSimpleApp will do this behind the scenes.

After correcting the wrapper.conf file, the JVM command should look like 
this:
---
java -Xms5m -Xmx64m -Djava.library.path=../lib
 -classpath ../lib/wrapper.jar:../lib/wrappertest.jar
 -Dwrapper.key=hJEaoVKN6ELBE6dI -Dwrapper.port=1786
 -Dwrapper.debug=TRUE -Dwrapper.cpu.timeout=10 -Dwrapper.jvmid=1
org.tanukisoftware.wrapper.WrapperSimpleApp jtapiApp.Main
---

Everything else looks fine.  Let me know if you have any other problems
getting things running.

Cheers,
Leif

Re: [Wrapper-user] If I start my application JVM restarts

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

Mirek,
Could you post your full wrapper.conf file and the contents of your 
wrapper.log
with debug enabled?
Please delete your existing wrapper.log file before running the test so 
you only
send the contents of a single run.  I only need the first restart.  By 
default the log
file will contain timestamps.

Looking at your configuration, It does not look like your jtapiApp.Main 
class is
on the classpath?  I just reverified this, but the WrapperSimpleApp will 
display a
nice descriptive error message in the event that the main class can not be
found.  This makes me think that what you posted is not your actual 
wrapper.conf
file.   Just post the unmodified log and conf file and I should be able 
to see the
cause.

The wrapper.ping.timeout should not be set in most cases.  It will not 
affect the
current problem you are having now anyway.

Cheers
Leif

[Wrapper-user] If I start my application JVM restarts

[<ms...@em...>]

Hello,
if I want to run my Java application with wrapper. Wrapper + application =
is running
but after start I always obtain this message:

wrapper  | Startup failed: Timed out waiting for signal from JVM.
wrapper  | JVM did not exit on request, terminated
wrapper  | JVM was only running for 31 seconds leading to a failed restar=
t count of 2.

It is running on RedHat Linux 9.0 + JDK 1.4.1 and wrapper 3.0.3

Here is sample my wrapper.conf file:
wrapper.java.command=3Djava
wrapper.java.mainclass=3Dorg.tanukisoftware.wrapper.WrapperSimpleApp
wrapper.java.classpath.1=3D../lib/wrapper.jar
wrapper.java.classpath.2=3D../lib/wrappertest.jar
wrapper.java.library.path.1=3D../lib
wrapper.java.additional.1=3DjtapiApp.Main
wrapper.java.initmemory=3D3
wrapper.java.maxmemory=3D64
wrapper.port=3D1777
wrapper.ping.timeout=3D0

Does anyone know where the problem should be?

Thanks

Mirek

Re: [Wrapper-user] Passing command line parameters to Java App

Max,
Could you post your wrapper.conf file, the output of your application
with the
wrapper.debug=true property set and your package.MyApp main method.
I should be able to tell you what your problem is then.

Leif,

 

   Thanks for replying to my message. Actually, I did not get this working
and I still can't pass command line parameters to my service. What I was
able to get working is the interactive mode for my service, so that I can
display a dialog, but it was mainly my fault on why it was not working.
Thanks again. Please let me know what I should do to get command line
parameters working.

[Wrapper-user] Re: FW: More information on message posted to SorceForge.net

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

Max,
Another user just asked me about this same thing in the Help forums:
https://sourceforge.net/forum/forum.php?thread_id=889788&forum_id=122338

Here is my excerpt:
---
If you are using Windows, then the easiest thing for you to do would be
to create a simple Java class which simply waits until 10:00am and then
calls the main method of your real application. The JVM would always be
running, but it would work.
---

I did a quick web search and was surprised that there is not much out there
to do cron jobs on Windows systems. I did find this application: BJS
http://www.camelliasoftware.com/
But it is a bit pricy 8-| Maybe I should make one of those....
Akso this one:
http://www.cosbatch.com/
I have never tried either of these or spent more than 5 minutes on their
sites.
If anyone knows of any other available tools please post.

For now I would suggest just writing a simple class that sits idle until a
specified time and then calls your application's main method. If your
application does not work correctly if the main method is called more than
once in the same JVM instance, then simply call WrapperManager.restart()
after the main method completes. The JVM will then restart and wait until
the specified time the following day. You should be able to get this up and
running in a few minutes.

Cheers,
Leif

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

I am switching providers this weekend so there is going to be a
hopefully short
period of time where the wrapper.tanukisoftware.org site will be off
line. I think
I got the DNS configured ahead of time so that the cache time is down to
10 minutes. But it may be possible that some users will have problems
accessing the size for up to 72 hours or so after the change over is

The SourceForge site will of course stay up as will this list as it is

Re: [Wrapper-user] Logging filter enhancement

[Mark P. <Ma...@so...>]

Leif,

> What you are asking for is to be able to hide an entire line of output if

Yes.

In general our logging needs are light.  We have a daemon job monitoring a
queue, it receives entries that cause it to run another products "command
line".  This command line dumps a bunch of output that we capture and log
as either INFO or ERROR based on the return code.

The only minor issue is that their command line spits out one or two lines
of copyright junk that doesn't really need to be in the log.  We can easily
filter it out in our code, but it would be cool if it could be done by your
filters.  Because, as I said, their copyright info could change with future
versions so if it was soft-coded in the conf file that would be nice.

Thanks for considering it.

Mark

Re: [Wrapper-user] Logging filter enhancement

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

Mark,
In your last message, you said that you were going to use the Wrapper log
methods to control log output.  One option would be to send the output at
the DEBUG level.  this way it would not be displayed in the console, or the
wrapper.log file by default.

Otherwise,  I would suggest using Log4j or Avalon's LogKit to handle
logging from within the JVM.  They will do a much better job than the
Wrapper is capable of doing from outside.

Features have slowly been added to the Wrapper's logging over time in
response to user needs, but it is not designed to be a replacement for
a real logging system inside the JVM.   Most applications that I write 
handle
all logging within the JVM by sending application output to a dedicated log
file.  Only error messages are displayed to the console.  This keeps the
contents of the wrapper.log file fairly simple and dedicated to startup,
shutdown, and critical errors.  I know it is all personal preference though.

I'll give your request some thought.  Each filter adds some load to the
system as all log output must be scanned against each registered filter.
What you are asking for is to be able to hide an entire line of output if
that output contains a specified token?

Cheers,
Leif

[Wrapper-user] Logging filter enhancement

[Mark P. <Ma...@so...>]

Would it be possible to add an action of IGNORE to wrapper.filter.action? 
IGNORE would mean to not write the message to the log.

I would like to use this to enter some log messages as triggers that we 
would rather not write to the log.  I have a process where I am logging 
all of the messages retrieved after running a system command.  Some of 
these messages are just copyrights etc..  It would be nice if I could 
filter them out in the logging framework instead of in my code.  That way 
the user could control it, and if the copyrights changed I could just 
filter them out by updating the wrapper.conf.

[Wrapper-user] Passing command line parameters to Java App

[Max S. <MSt...@li...>]

Hello,

 

    I am running into a problem when trying to pass command line arguments
to my application using wrapper configuration file. In documentation, it was
mentioned that I should use Wrapper.app.parameter<n> to do that.

 

So, if my command line looks like - "java package.MyApp c:\MyApp\list.bat" I
should break it down in the following matter in the configuration file:

 

            Wrapper.app.parameter.1 = package.MyApp

            Wrapper.app.parameter.2 = "c:\MyApp\list.bat"

 

I tried this, but the wrapper log file shows that
ArrayIndexOutofBoundException is being thrown by my main method when trying
to read args[0] in the following code:

 

 

Public static void main( Strings[] args) {

            String path = args[0];

}

 

Can someone please help me and let me know what I am doing wrong. Thanks in
advance.

Max,
    You will need to set the wrapper.ntservice.interactive property to true
and then uninstall and reinstall the service to get this working.
Unfortunately there is a bug in all currently released versions of the
Wrapper which breaks this for 1.2.x and 1.3.x versions of Java.  It will
work
correctly with version 1.4.0 and above but it is not currently possible to
display the GUI reliably with earlier versions of Java.  This has been fixed

I have tried to get this working a couple times but the problem is that if I
break these up then if becomes very difficult to keep the System.out and
System.err messages in the correct order when writing them to the log file.
As long as the output rate is low, things work file.  But If an 
application kicks
out a bunch of  err output mixed in with out output all at once, then 
the err
ouput will appear grouped together in the log file followed by the out 
output.
I'll take another look at it, but I am not optimistic about getting this 
working.
Currently it is not possible.

One thing I have thought about is replacing the System.out and System.err
OutputStreams with streams which will prepend all output with a "E:" or 
a "O:".
The Wrapper would then strip these off and apply the correct log level.  The
user should never see the above tokens in either the console or the log 
files.
I have avoided this solutions as it would place a load on the console 
output.
It is probably not significant enough that I should really be worrying 
about it
however.

The WrapperManager class will work perfectly whether the JVM is being
controlled by the Wrapper or not.  IF you wish to run from within 
Eclipse, or
elsewhere without the Wrapper, here is what you do:
Set the wrapper.debug property to true and run the application normally
using the Wrapper.  This will display the full Java command used by the
Wrapper to launch Java.   Copy this command into a small one line batch
file.  Remove the -Dwrapper.key=XXXXXX parameter.  Then run the batch
file.  Your application should start up and run normally.
For eclipse, you would want to duplicate this command line in the Eclipse
configuration.

Leif

[Wrapper-user] Logging level of System.err

[Mark P. <Ma...@so...>]

I just discovered this project today.  I cannot believe how great it works 
and how easy it is to use. 

Of course I do have a question/request:

Is it possible to make messages that are written to System.err be treated 
by the log as ERROR instead of INFO?  (I also entered this request on 
sf.net prior to joining the list)

If not, then I assume the only way to get that sort of functionality is to 
use your WrapperManager.log() method.  I would rather not do that at this 
stage in case we wind up needing to run this code in environments that are 
not using your Wrapper.  If I do use this method, does your code fail 
gracefully at runtime if I am just running my code manually, such as using 
the Run/Debug methods from Eclipse? 

Thanks

Re: [Wrapper-user] CTRL-C doesn't trigger controlEvent

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

Belo,
    You are absolutely correct.  The Java process was not correctly 
receiving
the CTRL-C signals when running under the Wrapper.  I had known about
this for quite a while, but it had never been a problem so I put it out 
of my
mind :-/  Sorry about that.
    Your mail prompted me to dig into in and I got it fixed.  Rereading the
MS C++ docs on the related APIs, it still looks like it should have been
working as it was.... Excuses, excuses.

    Anyway, this is fixed in CVS and will be in the next release.

    What is it that you are trying to do.  The Wrapper was correctly 
shutting
down the JVM when CTRL-C was pressed.  The only problem was that
the WrapperListener.controlEvent method was not being called within
the JVM.

Cheers,
Leif

[Wrapper-user] CTRL-C doesn't trigger controlEvent

[Voigt, B. M. <B....@kl...>]

Hi there!

I'm using the wrapper to exceute some java class, that has public void
controlEvent(int event) implemented.
I started the wrapper in a shell (cmd.exe).
My problem is, that the function is never reached when I press CTRL-C. When
I close the shell by clicking on the "x", log the user off or shutdown the
computer
everything works as expected.
In the WrapperManager class a native windows function for the windows event
is called. If the native function returns some non-zero value the
controlEvent function in my class gets called.
For CTRL-C there's a zero return value, so nothing happens.Am I doing
something wrong or ist the native function messing up?

Wrapper version 2.8.2 & 3.0.3 behave the same.
I'm using windows 2000 and jdk1.4.1.

TIA
Belo
