Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server versions   *
    *                  6.1 and 7.0 users of JavaServer Pages (JSP) *
    ****************************************************************
    * PROBLEM DESCRIPTION: There is a JSP compilation error when   *
    *                      using duplicate script variables with   *
    *                      NESTED scope.                           *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When using the WebContainer custom property
    'com.ibm.wsspi.jsp.useScriptVarDupInit' or the JSP attribute
    'useScriptVarDupInit',  the following error occurs if duplicate
    NESTED script variables are used:
    
    JSPG0049E: /iteratortag.jsp failed to compile :
    JSPG0091E: An error occurred at line: 16 in the file:
    /iteratortag.jsp
    JSPG0093E: Generated servlet error from file: /iteratortag.jsp
    /home/user/was/profiles/AppSrv01/temp/AppSrv01/server1/PM23597/P
    : 203 : Duplicate local variable index2
    An example JSP would be:
    
    <%@taglib uri="http://www.websphere.com/tags" prefix="cyc"%>
    
    <html>
    
    <body>
    
        <% if(2 == 2){ %>
        <cyc:iteratorTag index="10" name="index2">
            Index: <%=index2%> <br/>
            <cyc:defineVariable name="oneName" value="one"/>
        </cyc:iteratorTag>
       <% } %>
    
        <cyc:iteratorTag index="10" name="index2">
            Index: <%=index2%> <br/>
            <cyc:defineVariable name="oneName" value="one"/>
        </cyc:iteratorTag>
    
    </body>
    </html>
    

Problem conclusion

  • The JSP container was updated to not set duplicate scripting
    variables if the variables are of NESTED scope. Since nested
    variables do not get persisted past the end of the tag, there
    is no need to set them as duplicate variables when
    'com.ibm.wsspi.jsp.useScriptVarDupInit' is enabled.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 6.1.0.37 and 7.0.0.17.  Please refer to the
