Latest reply on Nov 12, 2012 by stefan1
I'm working on the loan request example from Chapter 5 and built my xml and used eclipse to get deployment artifacts (bar and jar files) which are also attached here for your reference

I copied the jar it built LoanRequestProcessChp5.jar in the following directory
C:\BPM\activiti-5.8\apps\apache-tomcat-6.0.32\webapps\activiti-explorer\WEB-INF\lib

But when I try to start the process from activiti-explorer I get the error listed below

Please Help!!
