[Wrapper-user] RE: where ot find output of System.out.println

From: Annam, S. <sun...@ea...> - 2004-06-07 15:08:54

Leif,
Wrapper.debug=3Dtrue is enabled.
The first statement in my code is=20
if (args.length < 1) {
System.out.println(" MobileGateway not started!" +
"Usage: java newproxyserver/Controller "
+
"<Properties file name>.");
System.exit(0);
}
try {
//Get the 'MG_HOME' env. variable.
mgHome =3D System.getProperty("MG_HOME", "..") + "/";
System.out.println("MG_HOME: " + mgHome);
....
....
}catch(...)
{
}
I am not getting any of the println in console output or wrapper.log.
Here is the output from wrapper.log

Sunil,
Please post questions to the wrapper-user mailing list rather than=20
sending them to me
directly. It makes them searchable for others having the same problem=20
in the future
and also makes it possible for others to answer the questions.
See below.

That message should be showing up in the wrapper.log file regardless of=20
whether
or not the MG_HOME system property is being set correctly.
Could you set the wrapper.debug=3Dtrue property and then post the
generated
wrapper.log file for a single run. This will give me a lot more=20
information about
exactly what is going on.

I am not clear exactly how you are specifying the location of the log=20
file in your
JVM. You can not reference a variable within the JVM using $JVM_HOME.
You will have to do something like:
System.out.println( "Path: " + System.getProperty( "MG_HOME" ) + "/logs"
);
In order to make that system property available, you will have to pass=20
it to the JVM.
Environment variables are not visible from the JVM on their own:
set.MG_HOME=3D/home/linux/pServer
wrapper.java.additional.1=3D-DMG_HOME=3D%MG_HOME%
The first will set the environment variable and the second will define=20
the system
property when the JVM is launched.

How are you launching the Wrapper? If you are using the sh script that
comes
with the Wrapper, could you try running it with the 'console' command
rather
than 'start'? This will run the Wrapper in the current console and make
it easier
to see the output that is being sent to the Wrapper process.
It will also make it clear that the JVM is indeed still running.

This makes me wonder if the JVM is actually running. What do you see if
you run
'ps -fax' You should see a tree of the processes running on your=20
system. Look for
the Wrapper and its JVM.
The script that ships with the Wrapper can also be used to check the=20
status of
the Wrapper process by running it with the 'status' command.
Cheers,
Leif
