websale example: problems with RemindActor timer action

[aapthorp]

I've just installed the 3.2.2 suite having not looked at JBPM for a while.

Having got the websale demo working I'm now experiencing the following error:

UnsupportedClassVersionError: Bad version number in .class file

which results in

JbpmJobExector:<my ip address>:1 leaves cyberspace

I think this has something to do with the RemindActor timer action, as I redeployed (no change made) this file immediately before I got the error. everything else seems to work apart from the timer.

Any ideas? I'm assuming this is a JDK / JRE version problem. I initially was seeing version problems with JDK 1.4.2 and upgraded to 1.5.0 13. Do I need to go to 1.6.0 1? This is the JRE that the Jbpm eclipse download seems to be using.

thanks

jbpm requires 1.4, but if you compiled your action with 1.6 and run it on less then you can get these problems if eclipse is not configured to produce 1.4 compliant byecode

Ronald,

Thanks, seems to be fixed now, it seemed to be a combination of compatibility and previous process instances not cleared out. How does jBPM handle existing processes when an updated process definition is uploaded? or can you point me to a descrption of this.

how about the normal docs? http://docs.jboss.com/jbpm/v3.2/userguide/html/jpdl.html#processversioning
