Hi Jil,
the server on which you want to run the application (where
the tomcat runs)
does not provide java6
see:
# Reason: You are trying to run a class compiled with newer
version of JDK.
For example, you have compiled the class with JDK 5.0 and
try to run on JDK
1.4.2. Class file major/minor version evolves with major JDK
releases. Each
JDK version supports only upto a specific class file
major.minor version.
1. Java SE 6 class file version 50.0 or below
2. JDK 5.0 class file version 49.0 or below
3. JDK 1.4.2 class file version 48.0 or below
While you can run a .class file compiled with past release
of JDK, the other
way around does not work. You can use javac's -target
option. Also, always
check version of "java" used to run your program
by using -version option.
so please either upgrade the jvm on the server, or use the
afore mentioned
option while compiling the source, and compile it compatible
to the target VM
Kind regards
Juergen
