RE: Unsupported major.minor version 48.0

Newman, Scott Fri, 12 Apr 2002 08:45:19 -0700

Does anyone know how in the name of all that's holy do I stop this error from occurring? I've upgraded from tomcat 4.0.3 to 4.0.4-b2, unistalled jdk1.4, unistalled and re-installed 1.3.1_02 and nothing makes it go away.

Help me, cause I'm stoopid.

This error is caused by upgrading from 1.3.1 to 1.4 of the JDK.

It is a funny thing. I shouldn't be getting them. The Tomcat is using 1.3.1_02, and that's what the web service was made with (as a matter of fact, the exact same ones, because they're both on the same machine), so it makes no sense to me. I am using the Eclipse build 20020321, so I was thinking maybe it's not switching the jre from 1.4 (which I also have, but only the jre, and tomcat needs the jdk, which the only version I have is 1.3.1_02). Glad to see I'm not the only person having this problem.

I get a similar error when I try to use jdk1.3.1_03 with my Java IDE.
It mystified me, so I'm avoiding 1.3.1_03 in favor of either 1.3.1_02
or 1.4.0. I'd sure be interested in what's up with this, as well!

Hi all

Does anyone get this error? It seems that I don't really get it until I include a utility library that I made that gets included into the class that is called via axis.
