I get the same exception for
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_08-b03)
Java HotSpot(TM) Client VM (build 1.4.2_08-b03, mixed mode)
Has any of your code been compiled with Java 5?
I have not installed Java5 at all... so the answer is no. I have only the JRockit jrockit-j2sdk1.4.2_05 and now the JDK1.4.2_08 (downloaded to test if this was the issue).
Darran is correct
was compiled with Java 5. I know that you say that you dont have Java 5 on your system, but 49.0 is the Java 5 marker.
When I compiled my classes with jdk-1.5 and used wscompile from jwsdp-1.5, I got an
(Unsupported major.minor version 49.0) error.
If I compiled my classes with jdk-1.4, I had to use wscompile from jwsdp-1.5
and if I compiled my classes with jdk-1.5, I has to use wscompile from jwsdp-2.0 .
Be sure to check your JAVA_HOME environment variable.
