@MrMagoo: there are a lot of people who are using the Spring integration without problems, so don't feel cheap ;-) Do keep us posted on your progress, I'm interested in seeing in what area we can improve things.

Hey there, I wish I could, but I dumped them a few weeks ago once I had JBPM3 all working. Regretting that now. Also there were about 50 variants. That in itself is wierd as the spring integration docs are only a few paragraphs. You guys tempted me with promises of a painless spring integrationnow I feel so cheated and cheap. ;) I will give it another hack when I have some time and be sure to keep a log and post then.

I'm not using Spring but I am getting this error when I'm executing multiple jobs in parallel using JBPM 4 and MySQL. I've been seeing all sorts of posts/blogs etc skimming this issue but none explaining the cause or if there is a solution. The problem I am having is my workflow doesn't always complete because of the errors. It seems like it's a little hit and miss and sometimes will carry on through to completion and sometimes not. http://www.jboss.org/index.html?module=bb&op=viewtopic&t=160253 Maybe should post in another thread.

Btw for reference, your jBPM4 issues are described here: http://www.jorambarrez.be/blog/2009/04/17/integrating-jbpm3-with-spring-part1/ It makes me wonder, since the GWT console uses JTA transactions. Can you post your configs here?
