Weblogic 6.1 service pack upgrade

[Undeployed]

Hi all,
I'm running weblogic 6.1 sp2, where i've one admin server and 3 managed servers.
Now we want to do product upgrade to weblogic 6.1 SP5.
We are not able to do it, after successfull install the application fails to start. It gives compilation errors.

Cann't resolve symbols, but i've checked that that classfile is there in classpath.

WE are upgrading only admin server, is that sufficient or we need to upgrade all managed servers separately.

But i think even this should not be reason for compilation problem.

Please help, we are stuck....

I think you have to do it all together, also check to make sure that youve not got any CR patches in your class path, and delete the temp directories beofre you restart the instances.

Yes these thing I'd already taken care off.
But problem was something else.

It was sequence of jar files in classpath, this sequence has to be according to supposed stack including application classes.

Thanks for reply.
