I notice you are using gcj, the GNU Java compiler. I think tomcat requires Sun Java. So it looks like you have not installed any Sun Java packages.

Thnx for your reply.

I have confirmed that JDK1.6 is installed and working. here is the output of the version checking command

java -version

java version “1.6.0_18”
Java™ SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot™ Client VM (build 16.0-b13, mixed mode, sharing)

and here is the output of JAVA_HOME

echo $JAVA_HOME

/usr/java/jdk1.6.0_18

I think problem is mainly cause by some missing libraries as you can see following line of stack print “java.lang.ClassNotFoundException: javax.management.modelmbean.ModelMBean not found”

But I really cant understand why tomcat cant find these required libraries :frowning:

Did you install tomcat from the openSUSE packages? It works if you use openSUSE packages as it should draw in any dependencies (JARs), but I haven’t messed with tomcat since 11.1 so I’m out of touch with this.

No we have our own some kind of customized tomcat server.
Anyway i have figured out the problem by looking at your point of view. You were right, tomcat by somehow was using JRE_HOME environment variable which was pointing to some gnu java, instead of JAVA_HOME variable which i modified. so adding and modifying JRE_HOME varibale in /etc/profile to point to the sun jdk fixed the problem.:slight_smile:
I genuinely appreciate your assistance.
Thanks a lot again.
