Hi!
I am getting the following unsupported class version error while running my application in NWDI for my DC. I reinstalled the NWDS with JDK 1.4 version ie j2re1.4.2_08. But still the problem persists.
ERROR DESCRIPTION:

Can somebody help me with this?

Hi Janice,
Please check all the installed java version in the system and run "javaws" at start > run and check the default version of java.
Also check the SAP Server and NWDI component and Check PAM (Product Availability Matrix) in the service market place for more details.

Hi All!
I could solve that error finally. The Error was not in the main DC but in one of the used DC which i had overlooked.
I repaired & reloaded the used DC. Then restarted NWDI.Built and deployed the used DC as well as the main DC. The problem was solved.
The UNSUPPORTED CLASS VERSION ERROR was infact very much misleading as it was nothing to do with the versions of the server.
Thanks to all your suggestions.
Regards,
Janice Baby

Hi!
Thanks for all your replies. I have done the checks on all what you had mentioned.But still facing this problem.So just briefing things all over again.
In my previous pc i had installed
1) SAP NWDS Version 7.0.18
2) J2RE SE V1.4.2_12
3) J2SDK SE V1.4.2_12
Server Details: J2SDK 1.4.2_13 (OS compatibility 64 bits)
Now my pc got replaced. I have installed the above mentioned softwares only. But still i am unable to figure why i am getting the major/minor class version error as while i was running the same application in my old PC it was working fine.
Should i get J2SDK 1.4.2_13 installed in my PC now? Can anyone suggest me how to solve this?
Any help would be really appreciated.
Thanks & Regards,
Janice

I think you have installed a higher version of jdk, like JDK5.
you can set the which jdk is used to build your dc.
go development infrastructure perspective.
select your development configuration
under Technology-Specific, make your configuration there
