Hi, Len. Thanks for the tip; this has been somewhat of a noodle buster for me, thus far. I confirmed that the "Server" actually has a 1.4 and a 1.6 JDK, but there's nothing for 1.3.
I managed to fix the problem, however, with a little bit of tweaking. I reinstalled Tomcat on the Server, and modified my build.xml on my development machine with "target" and "source" set equal to 1.4. Now it's running like a dream. It feels like my fix should not have worked, but I'm not going to complain too loudly about a functioning system. :-) Regards, Eric B On Tue, Apr 8, 2008 at 7:22 PM, Len Popp <[EMAIL PROTECTED]> wrote: > The error message "class file has wrong version 48.0, should be 47.0" > indicates that you're trying to run Java 1.4 code in a Java 1.3 JVM.
