Sample web app on jboss-4.0.3SP1

[mraja775]

I am trying to deploy the jbpm.war on a plain jboss-4.0.3SP1 server ( not in the starters kit). I copied all the jars from the sar(service archive) and included it as part of /WEB-INF/lib in the war file.

But during startup the server throws the following error

And also I am not able to view the first page of the sample application

Am i missing something here, or is there any additional configuration which needs to be performed

[mraja775]

I even wrote a InitializationServlet which binds the "JbpmConfiguration" object to "java:/jbpm/JbpmConfiguration" jndi name.
(The readme file in starters kit, specifies that the jbpm service archive binds the JbpmSessionFactory onto a jndi name. But the Mbean binds the JbpmConfiguration object. )

After this step I get the following error

javax.faces.FacesException: Cannot get value for expression '#{userBean.userSelectItems}'

Am I missing some obvious point here ?? Or is there a problem with running the sample jbpm web app on jboss 4.0.3Sp1

Thanks in advance

Try adding ehcache-1.1.jar from lib/hibernate. You should probably move the entire jbpm.sar directory to your JBoss installation rather than adding the classes to every web application that uses jBPM.

The stack trace you posted seems incomplete - is there a cause printed below?

[mraja775]

Alex, Thanks for your quick reply

My ultimate aim is to run the jbpm sample webapp on Websphere. I thot it would be better if I am able to make a war in plain vanilla jboss and then drop it onto Websphere.

But still I am not able to get rid of all dependencies. The root cause of the exception which I am getting is pasted below.

The CacheException persists even after i include the ehcache1.1.jar from the lib/hibernate folder

I think this could be a binary incompatibility between the JSF jars against which the jBPM webapp was build and the ones shipped in 4.0.3SP1. Try to build the jBPM webapp with the dependencies you find in 4.0.3SP1. You will have to do the same thing anyway if you want to deploy on Websphere...
