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

NAME
libglpk-java - GNU Linear Programming Kit Java Binding
DESCRIPTION
The GNU Linear Programming Kit (GLPK) package supplies a solver for large scale linear programming (LP) and mixed integer programming
(MIP). The GLPK project is hosted at http://www.gnu.org/software/glpk.
It has two mailing lists:
- help-glpk@gnu.org and
- bug-glpk@gnu.org.
To subscribe to one of these lists, please, send an empty mail with a Subject: header line of just "subscribe" to the list.
GLPK provides a library written in C and a standalone solver. The source code provided at ftp://gnu.ftp.org/gnu/glpk/ contains the docu-
mentation of the library in file doc/glpk.pdf.
The Java platform provides the Java Native Interface (JNI) to integrate non-Java language libraries into Java applications.
Project GLPK for Java delivers a Java Binding for GLPK. It is hosted at http://glpk-java.sourceforge.net/.
To report problems and suggestions concerning GLPK for Java, please, send an email to the author at xypron.glpk@gmx.de.
ARCHITECTURE
A GLPK for Java application will consist of the following
- the GLPK library
- the GLPK for Java JNI library
- the GLPK for Java class library
- the application code.
GLPK LIBRARY
The GLPK library can be compiled from source code. Follow the instructions in file INSTALL provided in the source distribution. Precompiled
packages are available in many Linux distributions.
The usual installation path for the library is /usr/local/lib/libglpk.so. The library has to be in the search path for binaries.
GLPK FOR JAVA JNI LIBRARY
The GLPK for Java JNI library can be compiled from source code. Follow the instructions in file INSTALL provided in the source distribu-
tion.
The usual installation path for the library is /usr/local/lib/jni/libglpk-java.so. The library has to be in the search path for binaries.
Specify the library path upon invocation of the application, e.g.
java -Djava.library.path=/usr/local/libjni
GLPK FOR JAVA CLASS LIBRARY
The source code to compile the GLPK for Java class library is provided at http://glpk-java.sourceforge.net.
The GLPK for Java class library can be compiled from source code. Follow the instructions in file INSTALL provided in the source distribu-
tion. The usual installation path for the library is /usr/local/share/java/glpk-java.jar.
The library has to be in the CLASSPATH. Specify the classpath upon invocation of the application, e.g.
java -classpath /usr/local/share/java/glpk-java.jar;.
SEE ALSO
Further documentation and examples can be found in the documentation path, which defaults to /usr/local/share/doc/libglpk-java.
