Error description

  • While migrating an application running under WebLogic towards
    WebSphere Application Server V8.5.5.10, we encounter an error
    with certain JSP pages.
    
    Here under the error stack:
    
    [02/09/16 14:29:19:735 CEST] 00000091 ServletWrappe E
    com.ibm.ws.
    webcontainer.servlet.ServletWrapper service SRVE0068E:
    
    One of the service methods of servlet [/test.jsp] generated an
    exception in application [App].
    Exception created: [javax.el.ELException:
    java.lang.IllegalAccessException: Class
    javax.el.BeanELResolver can not access a member of class
    javax.servlet.jsp.jstl.core.LoopTagSupport$1Status with
    modifiers "public"

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server versions   *
    *                  8.5.5, and 9.0 and Liberty                  *
    ****************************************************************
    * PROBLEM DESCRIPTION: An Expression Language (EL)             *
    *                      expression that processes the call      *
    *                      of method isLast() of an object         *
    *                      referencing the varStatus in a JSTL     *
    *                      for-each tag, generates a               *
    *                      java.lang.IllegalAccessException.       *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    If the JSP file below is run, the following exception will
    be thrown:
    javax.el.ELException: java.lang.IllegalAccessException: Class
    javax.el.
    BeanELResolver can not access a member of class
    javax.servlet.jsp.jstl.
    core.LoopTagSupport$1Status with modifiers "public"
    JSP file generating the exception:
    <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"
    %>
    <c:forEach items="${listOfValues}" var="entry"
    varStatus="statusVarExample">
    ${statusVarExample.isLast()}
    </c:forEach>
    Where ${statusVarExample.isLast()} triggers the exception.
    

Problem conclusion

  • The EL code was modified to correctly call public methods
    without throwing an exception.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.0.0.13 and 8.5.5.12 for WebSphere Application
    Server and 16.0.0.4 for WebSphere Application Server Liberty.
