Error description

  • Product Release: WebSphere Application Server Network
    Deployment edition, version 7.0.0.13
    Operating System: AIX 6.1
    Problem Description: When customer ran PerfServlet that comes
    with WebSphere Application Server 7.0.0.13 (PerfServlet 6.0)
    with "version=5" compatibility mode, customer saw the
    following error in trace.log:
    
    [7/27/11 9:46:59:889 EDT] 00000031 srt           1
    com.ibm.ws.webcontainer.srt.SRTServletRequest setAttribute
    this->com.ibm.ws.webcontainer.srt.SRTServletRequest@5b645b64:
    name --> perfservlet.exception value --> java.lang.Exception:
    Invalid tag name:
    {http://jk.massmutual.com/webservices/}webservices
    
    Customer has the following trace string:
    *=info:com.ibm.ws.pmi.*=all:com.ibm.websphere.pmi.*=all
    
    Customer stated he did not get expected output from PerfServlet.
    Instead, he saw this error.
    
    Verified that customer's PerfServlet contains the interim fix
    for APAR PK17553.

    ****************************************************************
    The error occurs due to the fact that the perfServlet fetches
    performance details for the server and then prints data in XML
    format. We try to create an XML Element as part of printing
    data in XML. Things works fine until a Tag which is not
    recognized is encountered, in which case perfServlet fails to
    idenitfy the Invalid Tag and dumps an Exception failing to
    output performance details collected.
    

Problem conclusion

  • In order to avoid this problem, those invalid tags are
    excluded or replaced with valid symbols, eliminating the
    possiblity of any exceptions while creating the Element and
    allowing for successful printing of perfServlet Data in XML
    format.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 6.1.0.41, 7.0.0.21 and 8.0.0.2 .  Please refer to the
