Finally I found a good tutorial on how to use the JBOSS IDE in Eclipse. So.. when i got to the part: right-click on the Tutorial project and select Run XDoclet. The XDoclet generation will display its output in the console... I didn't get what the tutorial said I should use, but I got: Buildfile: C:\Documents and Settings\wwkeg\workspace\Tutorial\xdoclet-build.xml N65540: BUILD FAILED java.lang.UnsupportedClassVersionError: xjavadoc/ant/XJavadocTask (Unsupported major.minor version 49.0) ~~~~~~~~~~~ I have no clue what is going on here.. can somebody help before I abandon jboss... Im running eclipse 3.1, bea jdk142_05, J2EE 1.4 libraries (JBoss-IDE) thanks please. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3992057#...
