Hi all,
I have installed and executed jbpm5 using ant project jBPM.install. When I try http://localhost:8080/designer/editor. I get a message: could not load process designer.
Server log show: ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/designer].[ProfileServiceServlet]] Allocate exception for servlet ProfileServiceServlet
java.lang.UnsupportedClassVersionError: Bad version number in .class file
Which is the problem?
