A couple of things:

  • Please take the time to choose an appropriate forum for your posts. This forum is for questions on Servlets. For more information, please click this link ⇒ CarefullyChooseOneForum. This post has been moved to a more appropriate forum: JSP.


  • Please be sure to use code tags when posting code to the forums. Unformatted or unindented code is extremely hard to read and many people that might be able to help you will just move along to posts that are easier to read. Please click this link ⇒ UseCodeTags ⇐ for more information. Properly indented and formatted code greatly increases the probability that your question will get quicker, better answers.


  • java.lang.UnsupportedClassVersionError: Bad version number in .class file almost always means that you compiled a Java class using a compiler from a version of Java newer than one in which you are trying to run. For example, compiling with a Java 1.6 JDK, and trying to run it in a Java 1.5 JRE.
