Error description

  • Error Description￘
    HttpServletRequest.getAttribute("javax.servlet.forward.query_str
    ing") returns null when it should be returning the query string
    specified after the question mark ("?") in a URL

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server version    *
    *                  6.1                                         *

    ****************************************************************
    * PROBLEM DESCRIPTION: Request dispatch forward attributes are *
    *                      not retained during subsequent          *
    *                      forwards.                               *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The request dispatch forward attributes must be set and always
    reflect the information in the original request even under the
    situation that multiple forwards and subsequent includes are
    called.  However, they are currently changed to reflect the new
    request attributes on every subsequent forward.
    

Problem conclusion

  • The WebContainer code was modified to retain the original
    request attributes during the dispatch forward.
    
    A new WebContainer customer property needs to be set to enable
    the behavior provided by this APAR:
    
    com.ibm.ws.webcontainer.keeporiginalpathelements = true
    (default
    is false)
    
    Please refer to the following technote for instructions on
    enabling WebContainer custom properties:
    http://www.ibm.com/support/docview.wss?rss=180&uid=swg21284395
    
    The fix for this APAR is currently targeted for inclusion in
    fixpacks 6.1.0.45 and 7.0.0.23 Please refer to the recommended
    updates page for delivery information:
