Action Executor fails to get application context

bkucuk — Thu, 10 Jan 2008 16:40:57 GMT

We want to use the action web service to start some content processing which uses the JCR API. Our action implementation successfully calls the Action Executer's executeImpl() method. However,executeImpl() returns the error message shown below when accessing the context as follows:ApplicationContext

Here is some code which should help:

Your client should first call the Alfresco authentication web service to get a ticket, then it can call your web service using that ticket.
