Is there any limitation to the JDK to be used with Websphere?

I have a Java application which uses PMIClient to access Performance data of my Websphere App Server.

I tried executing my program using Sun JDK 1.3.0 to access PMIClient on WAS AE 4.0.2, it failed, but the same program got the data with IBM JDK 1.3.0
I did a similar test with WAS AE 3.5.5 wherein I tried accessing the PMIClient with Sun JDK 1.2.2 and JDK 1.3 which failed and the same worked fine with IBM JDK 1.2.2.

Does this mean that WAS supports only IBM JVMs or am I missing some configuration?
Thanks in advance

Hi Honda,
Try applying the latest fixpak for your App Server. This helps in most of the cases

Latha,
I have all the latest fix packs installed.
The problem is not with the versions as it can be reproduced on both WAS 3.5.5 and WAS 4.0.2, its the problem with the JDKs

In WAS 3.x you need to obtain the "JDK conversion assistant" available at http://www-4.ibm.com/software/webservers/appserv/tools_intro.htm
Don't know if this is possible in WAS 4.

Graeme,
I have already tried using the JDK conversion assistant that didnt help. It still throws up exception regarding some classes not found

Graeme,
Just to add on to my previous reply.
If you check in the JDK Conversion Assistant tool page it should you should switch to only supported JDK and check Pre-req list for supported JDK, if you check the pre-req page it shows only IBM JDK for Win2k.

Yes.
For NT, 2000, AIX and Linux, you need IBM JDK;
For SUN, you need SUN JDK;
For HP, you need HP JDK.
Please check this page Supported prerequisites and APIs
