Java Development Tools

Hi! I just created a new simple app in JDev 11g and selected the JDK 1.4.2_16 for the model project. I created a set of business components from tables, built the project and them attempted to run the AppModule tester.

I got the following error:

Am I to assume that jdk1.4.x is no longer supported in JDeveloper and that I should start using JDK1.5.x? But apps built with JDK1.5.x are not supported in AppServer 10.1.2.0.2, which is J2EE 1.3 compliant... Does that mean that JDeveloper 11g is suitable only for apps deployed on OAS 10.1.3.x and above? (OAS 10.1.3.x is J2EE 1.4 compliant, and OAS 11g will be J2EE 5.x compliant).

Comments please.

Thx!
