Compatibility of WebSphere Application Server 6.1 with JRE 1.4.2

[ajeeb]

Hi,

I need to migrate a java based application currently running fine in WAS 5.3 server on Solaris using the WAS runtime of 1.4.2.

I need to move this application to WAS 6.1 server again on Solaris and use the WAS runtime 1.4.2.

I need to know is WAS 6.1 compatible with JRE 1.4.2?

If not, I am afraid I will have to use JRE 1.5 on WAS 6.1 which would mean possible changes in the application.

Please let me know or direct me to appropriate sources for reading which you guys already know might be helpful.

Uhm, the manual?

Please let me know of any appropriate manual if you already have or even have the links to. Search engines gives me a number of IBM redbook but nothing about the compatibility question I asked.

IBM wiki for websphere.

Now, Java 1.4 started end of life a few months after 6.1 was released...and 6.1 was released over a year after Java 1.5 was released.

I expect it's compatible, however since 1.4 is dead I would recommend upgrading anyway...I doubt you'll get much support help for dead software.

The documentation that came with the server. It will say what version of the JVM is required. You can, then, try to run on a lower version of the JDK, although it probably wouldn't work, and even if you could get it to work, it wouldn't be supported.
