with IDE 2.0 beta: running XDoclet failed

[ypan99]

When I follow the IDE tutorial (1.5.0) using 2.0 beta, I got:
Buildfile: C:\Documents and Settings\ypan\workspace\tutorial\xdoclet-build.xml
N65540:

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

Total time: 1 second

Here is my build file:
<?xml version="1.0" encoding="UTF-8"?>

Sorry somehow the build file was not attached properly. Here is again:

<?xml version="1.0" encoding="UTF-8"?>

The problem seems to be with your JRE version. Please make sure that you are using JRE 1.5 not 1.4.
