Oracle JDeveloper 3.2 Problem...

[larva]

Hi ,

I have installed J2SDK1.4.0 and also JDeveloper 3.2. I found that the files inside /JDeveloper 3.2/java1.2/jre/bin and /lib directory quite old so II overwrite all the .exe files inside these directories with the files I copied from J2SDK1.4.0. But when I run a simple application from JDeveloper 3.2, the following message come out :

E:\oracle\JDeveloper 3.2\myprojects\package2\Application1.java
Error: (0) initialization error: class Error const *: class file has wrong version 48.0, should be 45.3 or 46.0.

Eventhough I went to the menu Project->Project Properties and change the 'Target JDK version' to to J2SDK1.4.0 directory, the same error message come out also when trying to run a simple application.

Pls help...thanks !

Target means for which JDK version you want code for. But you can't simply replace the JRE 1.2 witha 1.4 version. You should stay for the IDE with the shipped JRE version, that is 1.2.

Hi,

So how can I use the latest version of J2SDK1.4.0 in Oracle JDeveloper 3.2 ?

First of all, you should do a clean install after you messed around with the JRE. Then install JDK1.4. And if you want to code for JDK1.4 then simply change the "Target JDK version" to JDK1.4: You have to point to the jdk1.4_home\bin - directory. I can't confirm the steps as I don't use JDeveloper anymore (I've heard the new version rocks 😉).

Forget it! It's impossible. I totally overlooked the "wrong class version" message you got. JDK1.4 comes with class version 48.0 but JDeveloper accepts only class versions up to 46.0. It's the same situation as with JBuilder 4 which is incompatible with JDK1.4, too. Sorry you have to take another IDE if you want to code for 1.4. Try Netbeans or Eclipse.
