This has to be something simple

Question

I'm trying to get to the point where I can develop JSR-168 portlets. I'm using JDeveloper 10.1.2 and the portlet wizard. I've created a simple Hello World portlet. I've also downloaded the pre-seeded OC4J, which is what I'm deploying to (if there's a better way--i.e., if I can use the oc4J that comes with JDeveloper, please let me know).
Deploying works fine. I'm having trouble, however, registering my local provider with our portal server. I get through the wizard as far as step 3 of 3, where it tells me:
There are no registration properties required by the provider for registration.
At this point, I get a message on my local pre-seeded oc4j which says:
07/01/24 10:47:19 Warning a client is using a different version of the ormi prot
ocol 1.0 != 1.1
This tells me that our portal has indeed contacted my local provider. I don't know if the warning issued means anything, though. If I click the finish button on the wizard, I then get the following error:
Error      
          An error occurred when attempting to call the providers register function. (WWC-43134)
An error occurred during the call to the WSRP Provider: Java stack trace from root exception:
java.rmi.ServerException: Internal Server Error (caught exception while handling request: oracle.webdb.wsrp.server.ContainerRuntimeException: An internal error has occurred in method <init>)
at com.sun.xml.rpc.client.StreamingSender._raiseFault(StreamingSender.java:384)

at oracle.webdb.wsrp.client.design.v1.OraWSRP_v1_Registration_PortType.register(Unknown Source)
. (WWC-43273)
I've looked up both of those WWC errors, but they don't give me anything to go on (the first one is an error when attempting to call the provider's register function, and the second is an error occurred when getting the service description).
I'm reading all about people developing and deploying JSR-168 portlets using JDeveloper and Oracle portal, so this has to be a problem that people have overcome. Any suggestions?
Thanks!

Answer 1

Okay; I figured this one out. I needed to create the database table mentioned in the Portal Developers' Guide. So much for "simply download, extract, and start OC4J." I can now register my portlet provider, and I can run a simple Hello World portlet from my local container on our portal server.
Now I'm trying to figure out how to debug a portlet (i.e., step through the code). If I try to remotely attach to the container running my portlet, JDeveloper can never find the container.
Because of the lack of replies to these posts, I have to wonder, is anybody else doing this? Is there anybody out there who can help me get up and running?
Thanks!
