Re: Unsupported major.minor version 48.0

[Ivan Filippenko]

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.  
 
Here's the trace:
