Notes: running in wsad using websphere app server 5.1 test environment with jdk 1.4 runtime and with programs compiled with jdk 1.4

Anyone know how to fix this problem ? - I know it's a mismatch of java versions but I thought you could use any JDK1.3 and above runtime to run Spring ?

Thanks
Richard

[richard Che So]

By the way.. I should add that Tomcat has no problems running this app using jdk 1.4

I'd say, that the mismatch occured rather due to your compiled classes, who's dependecies are out of sync, than the java-ver problem.

Check, that all your classes, jars etc. are compiled altogether. Try also to test them in another anvironment.

[richard Che So]

wsad runs this application fine when the hooked up to tomcat 4.1.3.1, using the same compiled classes, so it seems to be a websphere run time mismatch with the classes used in Spring ?.. Just a guess since I had a similar issue when I compiled and ran appfuse 1.9.1 under wsad .. the problem was with the jython.jar file in the wsad runtime libary which had an obsolete jakarta oro module..I downloaded the latest release of jython.jar and replaced it in the wsad runtime library (..\runtimes\base_v51\lib) and everything was fine.

Maybe someone could take a look at the runtime jar list for websphere5.1 and let me know the possible/probable culprits for this error ?

4,547,548 jython.jar
......
4,547,548 jython_Release_2_2alpha1.jar

theese 2 look absoulutely suspicious to me :)
I'd leave only one of them in a classpath.

also, try removing all jars, which are not used, it might help you as well.

[richard Che So]

Sorry, the jython.jar duplicate was my doing .. to fix the appfuse 1.9.1 problem, I downloaded the latest version (2_2 alpha1) and copied it to jython.jar replacing the existing one.... but all of this was done after the unsupported major/minor class version problem happened (I'm working on two projects at the same time)... so I don't think the problem is related to the jython.jar files .. unless spring uses something in them while wiring beans together ?

Thanks
Richard
