Hi Ronald, Thank you so much for your help..You are right as the problem was because of version mismatch between the jbpm I am using and that for esb.. As I am using jbpm version 3.2.3 and esb is using 3.2.2 and the scripts I executed priviously was from esb ..So then I found the mysql script file from jbpm-jpdl-suite-3.2.3 and executed it and then tested my same application and now it is allowing me to deploy my jpdl on db... Again thank you so much for your time and efforts Regards vnm View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4245619#...
