Unfortunately I get a strange behaviour with some web applications, if my JBoss EAP 5.0.0 is started with JBossAS Tools 2.1.0.v200912250601M-H198-CR1 from within eclipse.   I get this exception page in the browser:     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: An exception occurred processing JSP page /restricted/startseite.jsp at line 15   12:         <c:set var="content" value="${sessionScope[Constants.CONTENT_STARTSEITE]}" scope="page" /> 13:         <div id="seitenkopf"> 14:             <%@ include file="../common/seitenkopf.jspf"%> 15:             <sec:granted permission="#FiolaAccess"> 16:                 <c:if test="${not content.mitarbeiterGesperrt}"> 17:                     <%@ include    file="/restricted/common/workflow/menu.jspf"%> 18:                 </c:if>   Stacktrace:     org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:498)     org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:411)     org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:322)     org.apache.jasper.servlet.JspServlet.service(JspServlet.java:249)     javax.servlet.http.HttpServlet.service(HttpServlet.java:717)     org.apache.struts.action.RequestProcessor.doForward(RequestProcessor.java:1056)     org.apache.struts.action.RequestProcessor.processForwardConfig(RequestProcessor.java:388)     org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:231)     org.apache.struts.action.ActionServlet.process(ActionServlet.java:1164)     org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:397)     javax.servlet.http.HttpServlet.service(HttpServlet.java:617)     de.lbank.framework.web.struts.LActionServlet.service(LActionServlet.java:53)     javax.servlet.http.HttpServlet.service(HttpServlet.java:717)     org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)   root cause   java.lang.NullPointerException     java.text.MessageFormat.applyPattern(MessageFormat.java:422)     java.text.MessageFormat.<init>(MessageFormat.java:350)     java.text.MessageFormat.format(MessageFormat.java:811)       This error does not occur if I start my JBoss on the commandline and it does not occur if I start the server using the old version  JBossAS Tools    2.1.0.v200909110340M-H277-M3  of the JBoss tools.   ( If you wonder about the "#" character in my JSP. this is not the "#" from JSP syntax, but belongs to a bad third-party framwork we use (www.common-controls.com). )     Another strange thing with the newer version of JBossAS Tools is that the log output from JBoss is not always written to the eclipse console.     Do you have any ideas what's wrong?   Thanks Jochen -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/524770#524770
