JDeveloper 10.1.3 and OAS 10.1.2.0.2: I Give In

Still can't get the sample application built on Jdev 10.1.3 to deploy to my OAS 10g 10.1.2.0.2 app server. Spent lots of time browsing the OTN forums and Metalink and it mostly boils down to JDev 10.1.3 and OAS 10.1.2.0.2 using different JDKs. One fix (an unrecognized xml tag) got me past the first error, but new errors cropped up and now I'm throwing in the towel and downloading JDev 10.1.2.

I waste more time trying to configure Oracle than I actually do getting to develop on it.

PITA.

Update: I spoke too soon. After installing JDev 10.1.2 I discovered the tutorials I need to learn from are no longer available. So it's back to 10.1.3. Tomorrow I'll post a plea for help on the OTN JDeveloper forum. There's got to be a set of steps to get applications built on JDev 10.1.3 to work on OAS 10.1.2.

Fun With JDeveloper 10.1.3

While searching for the cause of my application's deployement problem, I discovered a post on the OTN forums where it was noted that applications developed with JDeveloper 10.1.3 that are deployed on OAS 10g 10.1.2 must be compiled using the Sun JDK 1.4, not the Sun JDK 1.5. The post, written by one of Oracle's JDeveloper evangelists, helpfully gave the reference for the howto. It is located in Section 22-11 of the Oracle ADF Developers Guide, 101.3

I don't know if this is the cause of my problem, and it isn't Oracle's fault that apps developed with Sun's JDK 1.5 won't necessarily run with JDK 1.4, and I'm sure it made sense to upgrade JDev to JDK 1.5, but it would be nice if somewhere on the download page for JDev 10.1.3 there was a big notice alerting folks of OAS 10.1.2 of this issue.
