Worklight 6.1 JPA errors in log: can not start application
问题 I have WL 6.1 Studio (on the top RAD 9.0.1) + WAS Liberty Profile 8.5.5.1 + WL 6.1 + Derby DB. At some point in time I started receiving errors and my WL application failed to start, from WAS log it seems that problem with JPA (or JPA classes loading conflict)? What can I check to fix it?
