I have one more question,i don't know this is chilly question or not.

If i upload the class files (jar file) to the classpath,then i upload the bar file from  the activiti explorer and start the process using explorer is it working fine or not.

Thanks,

Yes, that should work fine. Keep in mind, however, most containers (like tomcat) require a restart when in order to pick up classpath-changes… So just dropping the JAR in the lib-folder won't cut it, when using tomcat, reboot is needed.

I did this,when i put the jar file in the lib folder i stopped the tomcat after putting the file i start the tomcat.But in the activiti explorer i can't upload the bar file.
