Thank you guys for your help. It works now!

Woops, I guess I should have tried more before I replied.
Now I have issues -
The command I used
ps -ef | awk '/jbos[s]/ {print $2} some time return one number which is correct and I can kill the process using the number - that's what happened when I replied; but later I found that it sometime returned two numbers, the first one is not the right one so my program trying to kill the process failed and quit.
Then I logged on the remote machine and tried to get the jboss (ps -ef | grep jboss), I did see the output:
Quote:
[SERVER /]$ ps -ef | grep jboss
usr_name 364 31548 0 16:44 pts/0 00:00:00 grep jboss
root 32261 1 12 16:35 ? 00:01:04 /comp/java/bin/java -Dprogram.name=run.sh -server -Xms512m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=256m -Djava.net.preferIPv4Stack=true -Djava.endorsed.dirs=/apps/tparty/jboss/inuse/lib/endorsed -classpath /apps/tparty/jboss/inuse/bin/run.jar:/comp/java/lib/tools.jar org.jboss.Main -c comp
[SERVER /]$ ps -ef | grep jboss
root 507 1 0 16:44 ? 00:00:00 /bin/sh /apps/tparty/jboss/inuse/bin/run.sh -c comp
root 530 507 8 16:44 ? 00:00:57 /comp/java/bin/java -Dprogram.name=run.sh -server -Xms512m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=256m -Djava.net.preferIPv4Stack=true -Djava.endorsed.dirs=/apps/tparty/jboss/inuse/lib/endorsed -classpath /apps/tparty/jboss/inuse/bin/run.jar:/comp/java/lib/tools.jar org.jboss.Main -c comp
usr_name 952 31548 0 16:55 pts/0 00:00:00 grep jboss
You can see that my program returned the right number (32261) in the first trial, but after jboss was restarted, the second run of my program failed because it returned 507 and 530 (530 is the right one but program failed trying to kill 507 first).
I am new Linux user and would like to know why is that, and how can I modify my program (or the command) to make it always work?
Thanks,
Peter

LEARN ABOUT DEBIAN
jh_manifest
JH_MANIFEST(1) Javahelper JH_MANIFEST(1)
NAME
jh_manifest - Adds or/and modifies manifests for jars
SYNOPSIS
jh_manifest [debhelperoptions] [options] jar1 ... jarN
jh_manifest [debhelperoptions] [options]
DESCRIPTION
Javahelper tool to add or update manifests in a jar file. It can be used in two modes. If passed jar files, it will only process these jar
files. Otherwise it will update all jar files in the packages it acts on.
When processing a package, the debhelper(7) exclude option will make jh_manifest ignore matching jar files.
FILES
debian/package.manifest (or debian/manifest)
This file consist of a list of jar files and values to add to their manifests. Values in this file will take precedence over values in
the original manifest (and command line arguments over values in this file).
It is allowed to list a link in this file instead of an actual jar file, provided that the link can be resolved when jh_manifest
processes it.
If a jar file is listed here cannot be found, jh_manifest will print a warning, unless the jar file has been excluded.
As of javahelper >= 0.32, you may add comments in this file. If the line starts with a "#" it is completely ignored.
This file is ignored if jh_manifest is passed jar files via command line.
OPTIONS
-c classpath, --classpath=classpath
Sets the Class-Path attribute of all processed jar files to classpath.
If not passed, then the CLASSPATH environment variable will be used in the given jar file do not have a Class-Path attribute.
-m class, --main=class
Sets the Main-Class attribute to class in all processed jar files.
-o options, --javaopts=options
Sets the Debian-Java-Parameters to options in all processed jar files. This attribute is used by jarwrapper to start java with extra
options (e.g. to make more memory available).
-j /path/to/java/home, --java-home=/path/to/java/home
Sets the Debian-Java-Home attribute to /path/to/java/home in all processed jars. This attribute is used by jarwrapper to determine
which JVM to use.
EXAMPLES
An example debian/manifest file:
# use the symlink so we do not have to update with the next upstream release.
usr/share/java/my.jar:
Class-Path: dep1.jar dep2.jar
Main-Class: some.awesome.Class
usr/share/java/dep2.jar:
Class-Path: dep1.jar
SEE ALSO
debhelper(7)
This program is a part of javahelper and uses debhelper as backend. There are also tutorials in /usr/share/doc/javahelper.
