Question

Can anybody please help me with a link or document to run jbpm-5.2 on tomcat 7 using mysql as database ? Does jbpm deployment to tomcat require some other tool or repository or something else ? I am a complete novice to jbpm… Please help me.

Thanks in advance…

Answer 1

I had same problem and have posted a solution here (there is an ANT script referenced which can be downloaded):

To summarize what is required in order to install jbpm 5.2 onto tomcat 7 using the final full distribution:

1. Bitronix Transaction Manager : The distribution does not attempt to deploy / configure this despite the requirement. The above Ant installer will install Bitronix at the Tomcat Server level – advantageous as at this point BTM may be integrated into other projects on the platform.

2. The jBPM distribution is designed for JBoss AS server and the console / console-server packages include EL (expression language) libraries. These will conflict with those which are installed with Tomcat – the Tomcat EL should be preserved.

3. There is some confusion with respect to javassist jar in the config / config-server distributions.
   The included jars should be dropped – and included into both config / config-server javassist-3.4.GA
   The reason for this dependency is that Hibernate 3.4 is deployed as persistence layer in this distribution.

4. There is a conflicting dom4j library – dom4j-1.6.jar deployed with the console / console-server packages. This should also be removed.

5. It is not mentioned clearly that the parameter:
   -Dreporting.needcontext=true needs to be passed to the Tomcat JVM in order to allow the gtw-server to correctly instantiate the report module loader.

6. For the ‘Demo’ it is important to configure the human-server persistence correctly, and additionally address the includeantruntime issue during starting of this service.
