I've just installed the 4.0GA and opened my workspace with it and when I try to run the XDoclet I get the following error:

BUILD FAILED
java.lang.UnsupportedClassVersionError: xjavadoc/ant/XJavadocTask (Unsupported major.minor version 49.0)


what to do?

Thanks,

This usually means you are trying to run a class compiled with a compiler that created bytecode that the current VM doesn't understand.

What JDK are you using to run Eclipse? What JDK is the default in your System PATH (typing java -version from your console)

If you are using java5 you need to configure your xdoclet build settings to use java5 support.

1. Go to MyEclipse-XDoclet project properties page and then go to the "Build" tab.
2. Select java5 under the java language support.
3. Press OK

THen you should be able to re-run xdoclet and it should work.

You are correct. I am using Java5 outside to run Eclipse but my project compiles to JDK 1.4.2.

Still I looked under the xdoclet/build and it was already set to JDK5.

I ran it again just to make sure and it still give me this error.

I switched Xdoclet/build it to use JDK 1.4.2 language support and it all worked fine.
