Hello,
I would like to know if Apche Axis2 is actually copiable with java 1.5 as
stated in the installation guide
Iâm getting the error in the subject using Java 1.5.0_22
best

That error typically means your compiled classes and runtime JVM are
different major versions - for example you compiled your axis2 classes with
1.8 and tried to run axis2 in a web container using 1.5.

You can use Java 1.8 with the latest version of axis2.

If you still have problems, paste your entire stack trace.

According to the docs, 1.5 is supported by axis2.

https://axis.apache.org/axis2/java/core/docs/installationguide.html#requirements

Are you using the same compiler version to build your class files, as the
JDK version running your application container (tomcat) etc? You should use
the same major JDK version (1.5 should be ok) for compiling and running the
application.

Its hard to help further without a stack trace.

I would double check your Eclipse compiler level, even if it says you are
using 1.5. See here how that could go wrong:

https://stackoverflow.com/questions/2466828/java-lang-unsupportedclassversionerror-bad-version-number-in-class-file

I would also check the server logs to verify you are running 1.5, less
ideally you can run "java -version" in the OS shell.

If you are still stuck, I suggest you verify your axis2 is really the
version you think is running:

logger.debug("AxisServer class loaded from jar location: : " +
AxisServer.class.getClass().getProtectionDomain().getCodeSource().getLocation());
