Problem running Tomcat 4.0.4 under JDK 1.4.1

[Donie Kelly <do...@tecnomen.ie>]

Hi all,

I've upgraded to jdk 1.4.1 and Tomcat 4.0.4 and now my jsp pages give the
following error...

org.apache.jasper.JasperException: Unable to compile class for JSPerror:
Invalid class file format in
C:\mmsdev\tools\win32\jdk1.4.1\jre\lib\rt.jar(java/lang/Object.class).  The
major.minor version '48.0' is too recent for this tool to understand.
error: Class java.lang.Object not found in class
com.tecnomen.mms.relay.Alarms.

It works under JDK 1.3.1 and Tomcat 4.0.1, unfortunaly I upgrade both jdk
and tomcat together.

Some pointer to what is wrong would be great.,,
Thanks
Donie
