I'm new to JBPM. I have installed "jbpm-5.4.0.Final-installer-full". I import the sample project to eclipse. I run the project but when I type krisv in Human task panel in userId text but and press the refresh button I get the error below:
Exception during refresh: Server-side Exception: Command QueryTaskAssignedAaPotentialOwner failed due to Operation failed. Please contact task server administrator
How can I fix this problem?
