Yes, this turned out to be an anti-virus app going nuts as we wrote to

Good, so my understanding was OK, just my version wasn't as up-to-date 
as it could have been.

I will do that, especially because the wrapper is so well written that 
it is almost fully self-configuring - thank you to all contributors!

[Wrapper-user] jvm ping timeout

[Mark L. <ml...@bi...>]

I'm using wrapper v3.0.0 to run jBoss as a winNT service.

I was getting the following when trying to run our program on a W2K Server:

jvm 1    | 03:12:43,203 INFO  [STDOUT] The Wrapper code did not ping the JVM
for 31 seconds.  Quit and let the wrapper resynch.

We have actually solved the problem now, but during analysis I tried 
setting the ping timeout to 60 seconds with the following conf option:

wrapper.ping.timeout=60

The strange thing was, I kept getting the same error message (including 
the 31 seconds value)

Could someone tell me if I'm missing something here, or maybe this is a 
known problem with this version?

This should be working, I run with multiple JVMs all the time.  Just 
retested this and it is
working fine for me.   Could you enable debug output in the JVM that is 
exiting using
the wrapper.debug=true property then reply with your wrapper.conf file 
and the contents
of the wrapper.log file for a single JVM run?  I may be able to spot the 
problem.

Re: [Wrapper-user] JVM ping timeout

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

Mark,
    The Wrapper monitors the health of the JVM in a number of ways.  It 
is able to tell if
the JVM process crashes without any hooks in the JVM.  But a common 
failure mode for
Java is that the JVM hangs but does not crash.   In order to catch and 
recover from this,
the Wrapper pings the JVM once every 5 seconds and will kill the JVM if 
it does not
receive a response for more than 30 seconds (the ping timeout)

    First of all, I would look into what is causing your JVM to not 
respond for 30 seconds.
The most common cause of this is garbage collection on very large 
applications which do
not have enough system memory.  When the OS has to do swapping to be 
able complete
a GC sweep, the sweep can take a couple orders of magnitude longer than 
normal to
complete.

    Anyway, as you said, increasing the ping timeout will work around 
this.  But the
drawback to this is that it also increasing the amount of time before 
the Wrapper is
able to detect that the JVM has hung.

    As for your question about the wrapper.ping.timeout.  There was a 
bug fix in
version 3.0.2 which fixed this problem.   The pings were detected 
correctly from
the Wrapper side things, but there is analogous feature where the JVM 
will quit
to let itself be restarted if it has not been pinged by the JVM for more 
than 30
seconds.  Up until 3.0.2, this could not be set.  They are now both set 
using the
same wrapper.ping.timeout property.

    There have been lots of other fixes as well, so you might want to 
upgrade to
3.0.5, at some time.  At least go take a look at the release notes and 
see if any
of the changes may affect, or benefit you.

Re: [Wrapper-user] configuring Wrapper to run to java classes to run as one service. ..

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

Elhanan,
    After reading through all of this, the final problem is that the 
executable lacombi.exe
binary can not locate a required dll file.   I am not really clear how 
that relates to the
Wrapper?  Is that application being launched by one of your 2 JVMs?

    If the DLL is required as a JNI native library by one of the classes 
in your Java
application then you must include the location of the DLL on your java 
library path.
When you run Java without the wrapper, it uses a default library path 
that includes
the windows directory and user directory.   When running with the 
Wrapper, you
must set this manually in the wrapper.conf file.
    Since you can not locate this file anyplace, not sure if that is 
your problem
however.

    Other than that, it sounds like your 2 JVMs are starting up 
correctly.   Could you
please set the wrapper.debug=true property in both of your wrapper.conf 
files.  Then
reply with the 2 wrapper.conf files and wrapper.log files as 
attachments.  Please only
include the log output for a SINGLE JVM invocation.
    I may be able to spot something to help you out.

Cheers,
Leif

[Wrapper-user] JVM ping timeout

[Mark L. <ma...@bi...>]

I'm using wrapper v3.0.0 to run jBoss as a winNT service.

I was getting the following when trying to run our program on a W2K Server:

jvm 1    | 03:12:43,203 INFO  [STDOUT] The Wrapper code did not ping the JVM
for 31 seconds.  Quit and let the wrapper resynch.

We have actually solved the problem now, but during analysis I tried 
setting the ping timeout to 60 seconds with the following conf option:

wrapper.ping.timeout=60

The strange thing was, I kept getting the same error message (including 
the 31 seconds value)

Could someone tell me if I'm missing something here, or maybe this is a 
known problem with this version?

RE: [Wrapper-user] configuring Wrapper to run to java classes to run as one service. ..

[<el...@mi...>]

I'm sending this to both of u since I don't know exactly where the problem
exists

First I discovered I cannot launch the 2 class (compasserver,cas) in code
from the same jvm because compassserver locks cas.cfg
I know this because after remarking the first class (comapsserver) and
telling the batch file to raise the original class and then my class with my
code, only then it worked, by trying your code as u wrote it, the 2nd class
keeps saying that it could find the CASListenport on line 4 (which is in
cas.cfg, which it couldn't read I guess)

So I was left with the 2nd alternative:

After creating to adtional directories (confCAS,confSERVER) and modifying
and creating 2 install files, 2 run files, and 2 uninstall files (by simply
chaning each files conf directory to my own directories) I was able to
install the services.
After changing the conf files according I was left the following problems.
The classes won't run unless they will have server.cfg and cas.cfg in the
directory where wrapper.exe exists. Even though i specified the the root
directory in wrapper.java.class parameters 
Originally thought both files were in the same directory as the original
batch file.
This is not a major problem because after copying both files into 
Directories it seemed to work. Also comass also demanded the directory lacid
(also located in the root directory of the application) will be copied to
the directory of batch files
Now the real problem started when I tried accessing compass with java client
api sample... suddenly windows alerted the lacombi.exe needed the file
libsybdb.dll and couldn't find it. The strange thing is that I REALLY
couldn't find it, now in my entire c drive and not in the network directory
which contains the oracle.dll
Also I've checked lacombi with dependency walker an it really doesn't
reference this dll.

Running compass normally does not raise this error. I have no idea what is
this dll for.

Elhanan,
    Just like Java, the Wrapper only allows you to specify a single 
class when it it launches
the JVM.   In your application, you are launching the two classes in two 
different JVM
instances.
    There are a couple ways to do you may want to be doing.

1) Launch two copies of the Wrapper.  This can easily be done by 
creating two different
wrapper.conf files.   Either install them in different locations or take 
care that the log and
any pid files are named uniquely and things should work great.  If you 
are running under
NT you can even setup a dependency on the other server using the
wrapper.ntservice.dependency.<n> properties.

2) Depending on how your applications work.  You may also be able to 
simply run both
of your applications from within the same JVM.   To do this create a 
simple class that
does the following:

public static main(String[] args)
{
    Thread t1 = new Thread()
    {
       public void run()
       {
          CR.Compass.Server.CompassServer.main( new String[] {} );
       }
    };
    t1.start();

    Thread t2 = new Thread()
    {
       public void run()
       {
          CR.Compass.Server.CAS.CAS.main( new String[] { "0" } );
       }
    };
    t2.start();
}

    I didn't compile the above, but it should work.  Just specify this 
new class as the
first wrapper.app.parameter and then specify 
org.tanukisoftware.wrapper.WrapperSimpleApp
as the wrapper.java.mainclass.  It should work.

    If you found the support or the product useful, drop by the

RE: [Wrapper-user] configuring Wrapper to run to java classes to run as one service. ..

[<el...@mi...>]

How can I install the conf files in different directories, I'm assuming =
I'll
have to chage the batchfiels.
The files are depended on one another, the first one starts and listens =
to
port 4712 then the 2nd one starts and they both proceed a little =
further and
wait.

Usually this works fine. How ever when I tried your 2nd solution it =
almost
worked except the fact  that 2nd server didn't know what port to =
listen.
It reads this  information from cas.cfg file located in the =
application's
home directory

The directory structure is like this:
C:\compassrv\cs.bat which contains the original commands I told u about

C:\compassrv\cs1.bat which contains java.exe  -classpath
"C:\COMPAS~2\lib;C:\COMPAS~2\lib\compass320.jar" JavaServer

C:\compasssrv\cas.cfg which is the config file for the 2nd server
These classes are the one created from your code=20
c:\compassrv\lib\JavaServer.class
c:\compassrv\lib\JavaServer$1.class
c:\compassrv\lib\JavaServer$2.class

the original class from which I started
c:\compassrv\lib\compass320.class

I'm assuming that if run the class from another java class it tries to =
seek
the cas.cfg file in another directory (probably due to relative,maybe =
it
starts from another root directory), I don't know how to make as though =
I'm
running from this directory

[Wrapper-user] How to Invoke Thread dump from JMX in jboss

[brian m. <dea...@ho...>]

Hi all,

I'm new on this list and I must first say the wrapper is excellent! Thanks 
so much!

I'm running it on windows 2000 server and jboss. I was wondering if someone 
could tell me what parameters to invoke to get a Thread dump on jboss 
through JMX. I have the jmx services running but the parameters in the jmx 
console are confusing. Could someone tell me what to invoke and what 
parameters to pass?

I've looked at the docs but can't figure it out. Thanks very much,
Brian

Re: [Wrapper-user] configuring Wrapper to run to java classes to run as one service. ..

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

Elhanan,
    Just like Java, the Wrapper only allows you to specify a single 
class when it it launches
the JVM.   In your application, you are launching the two classes in two 
different JVM
instances.
    There are a couple ways to do you may want to be doing.

1) Launch two copies of the Wrapper.  This can easily be done by 
creating two different
wrapper.conf files.   Either install them in different locations or take 
care that the log and
any pid files are named uniquely and things should work great.  If you 
are running under
NT you can even setup a dependency on the other server using the
wrapper.ntservice.dependency.<n> properties.

2) Depending on how your applications work.  You may also be able to 
simply run both
of your applications from within the same JVM.   To do this create a 
simple class that
does the following:

public static main(String[] args)
{
    Thread t1 = new Thread()
    {
       public void run()
       {
          CR.Compass.Server.CompassServer.main( new String[] {} );
       }
    };
    t1.start();

    Thread t2 = new Thread()
    {
       public void run()
       {
          CR.Compass.Server.CAS.CAS.main( new String[] { "0" } );
       }
    };
    t2.start();
}

    I didn't compile the above, but it should work.  Just specify this 
new class as the
first wrapper.app.parameter and then specify 
org.tanukisoftware.wrapper.WrapperSimpleApp
as the wrapper.java.mainclass.  It should work.

    If you found the support or the product useful, drop by the 
following as well.

    Let me know if you have any other questions.

    Cheers,
    Leif

Re: [Wrapper-user] service in windows xp

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

Marcelo,
    Please give me a little more information.  What are you expecting 
the application to do?
Version 3.0.5 and earlier versions of the Wrapper are capable of 
displaying a Swing or
AWT GUI.  The GUI will be displayed correctly if you are using a 1.4.x 
version of Java.
Earlier versions have a problem which requires that the 
wrapper.ntservice.hide-console
property be set to false in addition to the 
wrapper.ntservice.interactive property being
set to true.

    Please make sure you have read over the following two pages:
http://wrapper.tanukisoftware.org/doc/english/prop-ntservice-interactive.html
http://wrapper.tanukisoftware.org/doc/english/prop-ntservice-hide-console.html

    In order for the service related properties to take effect, you must 
reinstall the
Wrapper as a service after making any changes.

    Version 3.0.5 does not allow you to display the console while 
running as a service.
This will be possible in the next release and is currently available in 
CVS if you need
it sooner.

    Cheers,
    Leif

Hi=85

i have the following batch file to run a java server:

=20

start java -cp lib\compass320.jar CR.Compass.Server.CompassServer

java -cp lib\compass320.jar CR.Compass.Server.CAS.CAS 0

=20

as u can see I need to invoke to 2 classes at the same time (which are =
from
the same jar)=85

=20

is there a way to do this in wrapper?

Lindsay,
    The Wrapper itself does not require a working display (X11)  But the
TestWrapper
sample application that is deployed with the Wrapper does.  This demo
application
displays a swing dialog that makes it easy for the user to try out
various features of the
Wrapper.

    Your message says that you are trying to get the James email server
working.  But
the stack trace in the log file is from the TestWrapper application.
As far as I know,
the James server does not have any kind of a GUI that would require a
display so you
should have no problems getting it running.

    Take a look at the page talking about how to get an application
integrated with the
Wrapper.   Let me know if you have any problems getting up and running after
reading that over.
http://wrapper.tanukisoftware.org/doc/english/integrate.html

    Actually, depending on the version of  James that you are trying to
run.  I think it
might actually have all the files you need to get up and running with
the Wrapper?
I have not checked.  But James is build on top of the Avalon Phoenix
server which
does fully support running with the Wrapper.  The Phoenix server comes
with a
wrapper.conf file that is all ready to go.  If your version of James
does not, then
look over the integration docs.  You should be able to get up and
running fairly
quickly.

RE: [Wrapper-user] Specifiying ClassPath in a single line?

the wrapper supports "*.jar".

  Subject: [Wrapper-user] Specifiying ClassPath in a single line?


  Hi folks,

  I have an application that I am trying to wrap in the Service Wrapper and
I'm having a problem with specifying classpath.

  Currently, I have an ANT target which loops through a lib directory
creating a single classpath argument which I pass to my executable script
via the -cp argument to the java command (java -cp @classpath@)

  I do _not_ know in advance how many jars are in my lib directory.

  So my problem is how to encode this info in the wrapper.conf file

  Questions:
  1. is there a way to set a multi-item classpath in wrapper.conf as a
_single_ property?
  e.g.  wrapper.java.classpath=../lib/foo.jar:../lib/bar.jar:../lib/baz.jar

  2. is there a way to tell the wrapper to add _all_ jars in a particular
directory to the classpath?
  e.g. wrapper.java.classpathdir=../lib

  3. What happens if I specify my classpath with a wrapper.java.additional
line? How will this interact with the wrapper.java.classpath entries?
  e.g.
  wrapper.java.additional.1=-cp ../lib/foo.jar:../lib/bar.jar:../lib/baz.jar


  Thanks for any help--hopefully one of these approaches works, 'cause
generating multiple entries and _counting_ in ANT (to produce
wrapper.java.classpath.N entries) is gonna be a bitch.

Re: [Wrapper-user] RE: Problem with the JVM not responding ( I have read the documen tation)

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

Todd,
Glad you got things working. Now that you mention this, I see what was
happening. Because you set the wrapper.java.additional property rather than
the wrapper.app.parameter property, your class name was being seen as the
main class by java when it was launched.

Let me know if you have any other problems.

Cheers,
Leif

Re: [Wrapper-user] Surviving Logon/Logoff

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

Eric,
    Could you set the wrapper.debug=true property and rerun your test?  
Then post
back with the wrapper.log and wrapper.conf file from one of the 
applications that is
failing on you.

    Without the log output I am guessing.  But what integration method 
did you use
to integrate with the Wrapper?  If you are using method #3 
(WrapperListener) then
it may be that you are not handling the LOGOUT event correctly in the 
controlEvent
method.  I should be able to tell from the wrapper.log/wrapper.conf files.

Cheers,
Leif

Re: [Wrapper-user] Problem with the JVM not responding ( I have read the documenta tion)

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

Todd,
Looking at the wrapper.conf and the log file that you posted. I am actually
stumped :-/ The JVM is timing out and being restarted because the
WrapperManager class is never being initialized and is thus never contacting
the Wrapper process. The thing that has be perplexed is how that could be
happening if the WrapperSimpleApp class has been specified as the main
class.
The first thing that is does is to load the WrapperManager class.

Normally you would see something like the following when the JVM is
launched:

For some reason you are not getting the Wrapper version line.

Could you please add the wrapper.debug=true property to your wrapper.conf
and rerun your application. Then repost the resulting wrapper.log file for a
single JVM invocation.

Please send the wrapper.log and wrapper.conf files as unedited attachments
So I can see exactly what you are doing.

Cheers,
Leif
