Gurus, please help I am getting oracle.apps.fnd.cache.CacheException

Question

Hi, I am not a newbie to OAF. I have worked good amount on the OAF 9i development. Currently we are on R12.0.4 and Jdev 10g (patch 6908968) But this error really beats me. I believe it could be due to a Apache error, but may be I am doing something wrong here and so hopefully you can provide me some insight. I am trying to configure my JDev 10G for R12 development. I am trying to run supplied HelloWorld page in Tutorial.jpr. I have set the DB connection and provided the username/password with responsibility key and also the DBC file in the Runtime Connections properties for the Project. I have also tried the alternative i.e building a custom HelloWorld, but even with that I get the same error.
Please let me know if I should be doing anything else.
Thanks and appreciate your help.
Rahul

Answer 1

I did thought it was a DBC issue before, so I requested the DBC file again from the DBA's. I try the page and get the same error again. This time I looked at the DBC and compared the JDBC string with what I have on the TNSNames. The server name on the DBC file provided to me was slightly off. So, that was the error. The dbc file had imbcdd-d as the server name, whereas in the TNSName it was imbcdd-b. I fixed the DBC and reran and there it goes I get the HelloWorld Page.
Thanks a bunch to all. I should have it investigated more. Apologize for the siilly post.
