      hi,

      we are using jboss-3.2.1 with resin-2.1.6 as web server. we are getting this strange error on sunOS 5.8.

      JDK version this time is j2sdk1.4.1_03
      com.caucho.jsp.JspParseException: error: Invalid class file format in /export/home/aniketvu/jdk/j2sdk1.4.1_03/jre/lib/rt.jar(java/util/logging/LogManager.class). The major.minor version '48.0' is too recent for this tool to understand. /export/home/aniketvu/jboss-3.2.1/server/resin-all/tmp/deploy/server/resin-all/deploy/mywar.war/40.mywar.war-contents/generalconfig.jsp:280: Class java.util.logging.LogManager not found.

      shifted to j2sdk1.4.2 and got this

      I use jdk logging api in my application and the development platform was windows 2000 with jdk j2sdk1.4.1_01.

      The application compiles with all the versions of jdk mentioned above and i always complied the application with different versions using ant. and i exported the JAVA_HOME for ant as well.

      cudnt figure out why this problem is arising.

      suggestions? comments? answers? directions?
