Version 4

    I start JBoss and try to access the jmx-console and get:



    HTTP Status 500, where the exception says org.apache.jasper.JasperException: Unable to compile class for JSP.



    Check to make sure that you have an environment variable JAVA_HOME set to a full JDK install (pointing to the root install directlory). 


    Also, check that you don't have a jar file available in your jre/lib/ext which provides a servlet/JSP api. This can cause incompatibility with the api provided by jboss and can render the pages of jboss unusable.


    Also, the reason for the following error


    +org.apache.jasper.JasperException: Unable to compile class for JSP


    Generated servlet error:

    The code of method _jspService(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse) is exceeding the 65535 bytes limit+



    could be a bug with tomcat as mentioned here at:
