Error trying to register a JSF Bridge Portlet in Tech Preview 3

Question

Hi,
If anyone has encountered this situation before, or has any advice as to a cause/cure, it would be greatly appreciated!
I'm following the instructions in the WebCeter Developer Guide - 'Creating Portlets with the JSP Portlet Bridge', and have completed thest steps:
1. Started the preconfigured OC4J and registered the sample PDK and WSRP sample Portlets successfully to the Resource Pallette
2. Created an application based on the WebCenter Portlet template
3. Created a connection to the OC4J instance
4. Created a basic jspx page containing an af:PanelContainer and af:Table, bound to a Data Control (which runs fine)
5. Created a portlet.xml ffile, using the 'Create Portlet Entry' for that page
6. Deployed the application to OC4J, and am able to successfully view the WSDL via the resulting URL
(http://localhost:6688/MyST-ViewController-context-root/portlets/wsrp2?WSDL)
7. Tried to create a new Resource Palette WSRP Producer Connection based on this URL as the producer Endpoint
And it stops me dead there with this error:
oracle.portlet.client.container.PortletHttpRuntimeException: HTTP <unknown method> request to url http://localhost:6688/MyST-ViewController-context-root/portlets/wsrp2?WSDL failed with status code 500 reason <unknown reason>. Please check that the producer url has been correctly specified, that the producer server machine and producer container are running, that the producer application is deployed correctly, and that the client can reach the server if behind a firewall.

Answer 1

I don't know what I was doing wrong, but I was fortunate in that this is a relatively small pilot app, so I tried creating a new WebCenter Application and performing these basic steps again within that application, and it worked!
I would still appreciate the feedback, if anyone has a suspicion of what would have caused this condition, just to avoid repeating it.
