Hey Peter, Thanks for the reply. Below is the type of exception message I get when this problem occurs. At the bottom of the message it says 'note The full stack trace of the root cause is available in the Apache Tomcat/5.5 logs.' These are the logs I'm trying to enable/view. How do I do this? Can these logs be filtered to include my application? Do you have any other suggestions on where I can look for the cause to this problem? TIA, Brian HTTP Status 500 - -------------------------------------------------------------------------------- type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception org.apache.jasper.JasperException org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:370) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:314) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264) javax.servlet.http.HttpServlet.service(HttpServlet.java:810) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81) root cause java.lang.NullPointerException note The full stack trace of the root cause is available in the Apache Tomcat/5.5 logs.
