Portlet unavailable

Question

I'm working on the WebCenter Framework Tutorial. I was able to deploy and run my portlet in Step # 6. In Step # 7 (Adding Some Simple Logic ot the Portlet) I now get a "Portlet Unavailable" error when I try to run my portlet. I checked to verify that OC4J is running by going to the Connections Navigator tab->MyLocalOC4J and selected properties. From the test tab I checked the test button and had a successful connection.
When I right click on the MyPage.jspx and click run it gives me the "Portlet unavialable" error message in the page that it opens up. Here is the rest of the error message. If you can help I would greatly appreciate it.
Thanks...

Answer 1

Hi,
The error messages seems to indicate that there is some kind of mismatch between the consumer and the provider regarding the soap messages. This can sometimes happen when the specs of the portlet change: adding of portlet communication parameters in the oracle-portlet.xml for example, or registering of security roles. Here are some steps:
- restart the webcenter container
- stop the embedded OC4J
- refresh the portlet registration in the consumer project
- check if the portlet on the page is still having correct bindings, or delete the portlet from the page and put it on again
- retry.
- if any errors are left, also check the application.log of the deployed portlet project for any detail errors. Portlet-application specific error messages do not always appear in the container logging, but can end up in the application log file.
Success,
