Problem running jbpm maven project in JBPM-6.1.0.Final

[ken_re]

I downloaded jbpm-6.1.0.Final-installer-full.  I unzip it and did an ant install.demo.  Then I tried to install a jbpm maven project.  That was completed with not problem but when I went to run ProcessMain as a java program I get the following error:  Does anyone know how to fix this problem.  If I use the previous release I works.

problem might be that you running on data base that was created with previous version and because of that causes some issues. Since you're running installer make sure that you do clean.demo and then install.demo again and the problem should go away.
