Error description

  • After redeploying a WebSphere XD batch application with either a
    new
    resource reference for a non-XA datasource or a new batch step,
    the user sees
    naming exceptions because the new references could not be found.
    After
    restarting the application server we no longer see the
    exception.
    
    ----------------------------------------------------------------
    i.e.:
    With the new app, a new resource reference is introduced:
    (java:comp/env/jdbc/WXD_T2), but here's what is seen in the
    NameSpaceDump:
    
      14 (top)/comp/env/jdbc/WXD_T2
       14    ERROR: Could not instantiate a bound object.
       14    Bound Java type: java.lang.Object
       14    Local Java type: NULL
       14    String representation:
       14    Source object is a javax.naming.Reference.
       14       Reference factory class name:
    com.ibm.ws.util.ResRefJndiLookupObjectFactory
       14       RefAddr[0]: Type: ResRefJndiLookupInfo
    Content: com.ibm.ws.util.ResRefJndiLookupInfo@1e681e68
    ResRefJndiLookupInfo: Look up Name="jdbc/WXD_T2";JndiLookupInfo:
    jndiName="jdbc/WXD_T2"; providerURL=""; initialContextFactory=""
    
    ----------------------------------------------------------------
    
    Steps to reproduce the issue:
    
    1.  Install WXD_IVTPlain (sr-wxd-ivt3-ear-1.0.ear) in your UTE.
    On purpose this application version is missing some resource
    references
    that will cause a NamingException.
    2.  Restart the application server.
    3.  Run the EJBErrorTest_CrusorHoldable.xml via Job Management
    Console
    4.  Stop the enterprise application WXD_IVTPlain
    5.  Deinstall the enterprise application WXD_IVTPlain
    6.  Install the new Version of WXD_IVTPlain (
    sr-wxd-ivt3-ear-1.1.ear)
    that will have the missing resource references
        ***   DO NOT RESTART THE APPLICATION SERVER   ***
    7.  Run the EJBErrorTest_CrusorHoldable.xml via Job Management
    Console
    8.  The new introduced resource references should be accessibl
    via
    local JNDI Namespace (java:comp/env/jdbc/WXD_T2). The resource
    reference is added to the BatchControllerBean but the running
    enterprise application does not find it. In this example the
    error
    happened in the BatchDataStream->open() where the existing
    resource
    reference is not found even it's there:
        System.out: [09/30/09 18:02:07:650 CEST] ERROR
    JDBCBatchDataStreamReader - open:  Caught NamingException:
        javax.naming.NameNotFoundException: Name comp/env/jdbc not
    found in
    context "java:".
    9.  Now restart the application server
    10. Run the EJBErrorTest_CrusorHoldable.xml via Job Management
    Console
        ***   Now the problem is gone   ***

Local fix

  • Only workaround is to restart the application server

    ****************************************************************
    Steps to reproduce the problem
    -----------------------------------
    1. Install Application with two EJBs EJB1 and EJB2
    2. EJB1 does a lookup on EJB2 which works fine
    3. Update the application to have one more EJB, EJB3 and modify
    EJB1 to do a lookup on both EJB2 and EJB3
    A NameNotFound exception is thrown.
    Only a restart of the server could make the lookup of the
    other resource work.
    

Problem conclusion

  • The component metadata cache which is used to map the name
    with component metadata was not updated with other resources
    when the application is updated.
    Code has been modified to accomodate the same.
    
    APAR PM31103 is currently targeted for inclusion in Service
    Level (Fix Pack) 7.0.0.15 of WebSphere Application Server V7.0.
