BPEL

[twallmey]

Hi all,

I'm trying to install the "hello"-BPEL example for hours now. Would be great if someone could give me some hint where the problem is. Here is what I've done so far (just followed the getting started tutorial):

I've installed JBoss application server and jbpm-bpel (pls. see attached versions below). I can access the jBPM-web-console, could generated the database scheme - all without any problems. But when I try to deploy the "hello" example I get the following error message (stack trace) on jboss console (deployment is done with unchanged ant task "deploy.process"):

I'm looking forward to your responses and ideas!

I'm using currently using:
- JBoss 4.2.2GA
- jbpm-bpel1.1GA

Hi,

I also got a similar problem with jboss 4.2.2.GA. Then I tried with Jboss 4.0.5.GA and examples are working fine.
Try it out with Jboss 4.0.5.GA

Are you using JDK 1.6? Seeing the stack trace, it must be the same problem reported in http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4126422, for which we already have a solution.

The current workaround is to use JDK 1.5. You can stay on JBoss 4.2.2.GA or try JBoss 4.0.5.GA, as shefagarwal suggests. But the key point is to avoid JDK 1.6.

Hi Alex,

thanks for your info! In deed I'm currently using JDK 1.6. I'm going to change this and let you know if JDK 1.5 works better.

After changing to JDK1.5 everything is working fine now! Thanks a'lot. Does this problem only occur for the examples or is it recommend to use JDK1.5 instead of JDK1.6 for all BPEL related applications?

Regards,

Thorben
