Hi,
I have the same situation. "Run-app" with plugin version 5.12.1, Grails 2.3.0 and Hibernate4 or Hibernate3 results in:

| Server running. Browse to http://localhost:8080/grailsActiviti
Configuring Activiti Process Engine ...
... finished configuring Activiti Process Engine.
Error initializing the application: null
java.lang.NullPointerException

at java.lang.Thread.run(Thread.java:722)
| Error Forked Grails VM exited with error

The error message does not give much valuable information, so I don't know where to start with debugging.

Yours Johannes

Thanks for provide addition information. I did aware about this issue but couldn't find time to look into it at this busy moment.

I spent the weekend trying to make the plugin work with Grails 2.3.0, but I am out of luck. Please see the details at http://forums.activiti.org/content/running-activiti-engine-springframework-324

You might want to post your problem on the grails mailing list. I am not sure that the activity-forum users know enough about grails' internals.

Edit: I just posted the question with a link to this page.

Grails 2.3 has serviceBeanAliasPostProcessor, it will auto create alias for all Service artifacts, but all activiti service, such as runtimeService and repositoryService, is not real grails service artifacts. So define these name is end with 'Service' will cause error. So we can change runtimeService to runtimeServ or other name, then activiti can work normal in grails 2.3.

I open a defect for grails, link: http://jira.grails.org/browse/GRAILS-10690

[limcheekin]

Thanks for sharing your finding, workaround and created a Grails JIRA issue.

[zhaosd]

You are welcome! I am very glad to do this.

Hello zhaosd..I'm wondering can you elaborate on your workaround. I've struggling with this the last day or two.
I'm not sure where I should change the name from runtimeService to runtimeServ. Is it in the ActivitiService class itself or what other locations do I need to modify it in?

If you use grails-activiti plugin source code directly, you can change the file 'ActivitiGrailsPlugin.groovy' in source code. You can find these services reference is defined in 'doWithSpring' closures. If you use plugin dependency mode to use this plugin. You can open eclipse 'Navigator' view, then '.link_to_grails_plugins/activiti5.12.1. You can find the file 'ActivitiGrailsPlugin.groovy'.
This problem is already fixed in grails 2.3.2, if you are not ugent to use it, you can wait grails 2.3.2 release.
