FlashBack to JDeveloper 10.1.2.2.0

" I want to migrate my application code base from JDeveloper 10.1.3 to 10.1.2 "

One of my colleagues recently faced this problem of moving the source code of a J2EE Application from Jdeveloper 10.1.3 to JDeveloper 10.1.2.

We faced a few issues during the process & here's a partial list of the issues we faced :-

1. Platform Migration Issues

JDeveloper 10.1.2.x makes use of JDK 1.4, whereas JDeveloper 10.1.3.x makes use of JDK 1.5. Hence, the move involves changing Java code to ensure that the code is stripped of all the useful features we are used to in JDK 1.5. E.g: contains() method of java.lang.String, etc.

2. “Error (n, m): identifier OracleJspRuntime not found”

We noticed that we had to manually add the JSP Runtime Library to the new Project in jDeveloper 10.1.2.

Please see one of my previous posts for more information about this problem.

3. Error: JSP files must reside in the server root directory or a subdirectory

We noticed that we had to manually change the HTML Root Directory to the new Project in jDeveloper 10.1.2.

Please see one of my previous posts for more information about this problem.

4. Change XSD references to DTDs

The JDeveloper 10.1.2.x does not recognize references to XSDs in web.xml & other configuration files. Hence, we had to manually change these references to DTDs.

Well, we managed to backport the application after resolving these problems. I would like to hear if there are any other similar experiences.
