Re: [jboss-user] [jBPM] - Error while deploying the JBPM project from eclipse

Maurice de Chateau [http://community.jboss.org/people/MohReece] replied to the discussion "Error while deploying the JBPM project from eclipse" To view the discussion, visit: http://community.jboss.org/message/538942#538942 -------------------------------------------------------------- Hi Sameer, If you're getting an IncompatibleClassChangeError, something is seriously wrong! I never experienced this with jBPM myself so far, and looking up what it could mean turned up the following description: "+This situation occurs when the current definition of the referenced class is incompatible with the definition of the class that was found when the referring class was compiled. For example, say class+ +A+ +refers to a method in class+ +B++. Then, after class+ +A+ +is compiled, the method is removed from class+ +B++. When class+ +A+ +is loaded, the run-time system discovers that the method in class+ +B+ +no longer exists and throws an error.+" To me, this says that there may be two different versions of jBPM in your environment (with at least incompatible versions of the class org.jbpm.job.ExecuteActionJob). Could it be that there is a different version of jBPM either referenced from within Eclipse or in the deploy or lib directories of you JBoss AS? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538942#538942] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [JBoss Cache] - NullMarkerNodeForRemoval issue

And it looks like org.jboss.cache.invocation.NodeInvocationDelegate is not expecting a node wrapper on a null node, which seems to be NullMarkerNodeForRemoval -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538941#538941] Start a new discussion in JBoss Cache at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[jBPM] - Empty string process variable on Oracle 9i

by Martin Pradny

Martin Pradny [http://community.jboss.org/people/mpradny] created the discussion "Empty string process variable on Oracle 9i" To view the discussion, visit: http://community.jboss.org/message/538936#538936 -------------------------------------------------------------- I've just moved jbpm 4.3 application form my test environment on MySQL to customer's test server which storing data in Oracle 9i. I process I'm using process variables and test them in decision nodes, eg. is there is something take one path, otherwise take different one. Problem is that when I store empty string variable in the database is physically stored null. When I try to read it back in EL I get error that variable has not been found. I have found thread discussing handling null values in EL, but this is slightly different case. If I store "" I want to get "" back. This should be completely transparent for the jbpm engine. Am I missing some configuration in hibernate? I don't want to use solution that I would store some fake value instead of empty string e.g. "$$this_is_really_empty" :^0 .

It seems you are using a jbpm 3 plugin to deploy jbpm4. But they can't worked togethor.

It's considerably slower when a bridge method is passed in. Then again the problem would move to the proxy, so I don't see a way to gain. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538918#538918] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
