Error description

  • WS-Notification Broker application fails when processing
    requests with a java.lang.NullPointerException.  The exception
    reported in SystemOut has the form:
    
    Exception:java.lang.NullPointerException
    SourceId:com.ibm.ws.sib.wsn.webservices.impl.inbound.provider.WS
    NProvider.invoke ProbeId:1:143:1.1
    
    Reporter:com.ibm.ws.sib.wsn.webservices.impl.inbound.provider.NB
    ProviderImpl@4ba3f552
    
    java.lang.NullPointerException

    com.ibm.ws.sib.wsn.webservices.impl.inbound.provider.NBProviderI
    mpl.invoke(NBProviderImpl.java:108)
    ..
    

Local fix

  • configure the
    JVM system property com.ibm.websphere.ejb.UseEJB61FEPScanPolicy
    to a
    value of true
      The JVM system property will require a server restart to take
    effect.
    
      To set a JVM system property for the app server the admin
    console can
    be used:
    
    +Servers+Server Types->WebSphere application servers
    select server
    +Server Infrastructure/Java and Process Management
    select Process Definition
    select Additional Properties/Java Virtual Machine
    select Additional Properties/Custom Properties
    then click on the New button

    * PROBLEM DESCRIPTION: WS-Notification protocol requests made  *
    *                      to the broker application fail with a   *

    * RECOMMENDATION:                                              *
    ****************************************************************
    The WS-Notification Broker application shipped in the product
    requires that the scanning for additional meta-data for
    pre-J2EE 5 modules is performed.  The default for this
    behaviour changed in version 9.0 of WebSphere Application
    Server so that the additional scanning is no longer being
    performed.  This resulted in the injected
    javax.xml.ws.WebServiceContext being null.
    

Problem conclusion

  • The module manifests of the WS-Notification Broker
    application's were modified so that the UseEJB61FEPScanPolicy
    attribute was specified as true, enabling the additional
    scanning for those modules.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 9.0.0.6.  Please refer to the Recommended Updates
    page for delivery information:
    http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
    

Temporary fix

  • Setting the JVM system property
    com.ibm.websphere.ejb.UseEJB61FEPScanPolicy to a
    value of true will enable the additional scanning, for all
    applications, required for the WS-NotificationBroker
    application.
