jBPM Designer throws Nullpointerexception from solder-impl jar
Does anybody know what the reason for that NullpointerException could be? I am using tomcat server as webserver. Until today everything worked fine. But now I get this exception.
In my opinion the reason is that someting destroys the application context but what could be the reason for that?
