Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server Version    *
    *                  7.0 and 8.0 users of JSP documents.         *
    ****************************************************************
    * PROBLEM DESCRIPTION: JSP documents (JSP files in XML         *
    *                      format) which use a default XML         *
    *                      namespace will cause a                  *
    *                      NullPointerException during             *
    *                      translation.                            *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    In the sample JSP document below, the default XML namespace is
    http://example.com/mytag, which the custom table tag should
    use:
    <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"
    xmlns="http://example.com/mytag" version="2.0">
    <table />
    </jsp:root>
    The above JSP document will cause the following exception:
    com.ibm.ws.webcontainer.webapp.WebApp logError SRVE0293E:
    [Servlet Error]-[java.lang.NullPointerException]:
