    java.lang.UnsupportedClassVersionError: on build

    David Sternberg Newbie

      I am getting the following error when I run the my build.xml file with the jboss eclipse ide:

      java.lang.UnsupportedClassVersionError: com/sun/tools/javac/Main (Unsupported major.minor version 49.0).

      I'm just trying to get a simple controller class working that extends HttpServlet.

      I looked at the version of java I am running and it is 1.4.2_10.

      This is already turning me off to Java development.

      Please Help.
