Clean out old cached workflow models

[acgrama]

After successfully deploying a custom workflow (using the epes-bc2wf namespace), I deleted the workflow definition, context and model files from alfresco_4.2.a\tomcat\shared\classes\alfresco\extension. I have also cleaned out the corresponding GUI definition from alfresco_4.2.a\tomcat\webapps\share\WEB-INF\classes\alfresco\web-extension\share-config-custom.xml.

However, when I start Alfresco, not even the standard workflows are available in the workflow selection list, and in the log I see the following error:

10:28:26,385 ERROR (org.springframework.extensions.webscripts.AbstractRuntime)

I have searched, and the "epes-bc2wf" namespace is not defined anywhere except in alfresco_4.2.a\alf_data\postgresql\base\18277\18278. Is this some sort of caching mechanism in Alfresco? If yes, how can I clean out the old definitions?

Solved – the undeploy process had not been finished cleanly. I managed to undeploy the processes via the admin console, and it is fine now.
