Error description
The following restrictions apply to the use of WSIF SOAP client
invocations:

    * The mixing of WSIF SOAP client invocations with J2EE Web
Service client invocations in the same client environment is
not supported.
    * The use of WSIF SOAP client invocations local to a
WebSphere Application Server can cause problems in J2EE Web
Services deployed on the same Application Server.
    * The use of a Web Services Gateway deployed on a
WebSphere Application Server can cause problems inn J2EE Web
Services deployed on the same Application Server.

An attempt to invoke a J2EE over JMS web service after any
WSIF SOAP over HTTP or SOAP over JMS client invocation will
return the following error and the request will not be sent:

TRAS0014I: The following exception was logged
java.lang.NullPointerException  at com.ibm.ws.webservices
.wsif.providers.soap
.WSIFJmsSender._invoke(WSIFJmsSender.java:126)

Any WSIF SOAP over HTTP or SOAP over JMS client invocation
(including implicit WSIF client invocation via the Web
Services Gateway) can cause various problems relating to
Security, Internationalization, Request Metrics, Performance
Monitoring and Transactions in J2EE Web Services deployed on
the same Application Server.

****************************************************************
To support SOAP over JMS, WSIF registers its own Transport
implementation class with the Web Services Engine. The way
in which this registration is done is that for the "jms"
protocol, all Web Service services and clients in an
application server will use the WSIF Transport
(the WSIFJmsSender class). Any attempt to get a Web Service
engine configuration will return the WSIF web service engine
configuration.

If there is therefore a JAX-RPC Web Services client which
wishes to use the Web Service engine JMS Transport, and it
is invoked after a WSIF client has sent a SOAP over JMS
request, then this Web Services client will use the
WSIF JMS Transport. Because the Web Service engine has not
set up WSIF-specific objects, the WSIF Transport will fail
with the following error:

TRAS0014I: The following exception
was logged
java.lang.NullPointerException  at
com.ibm.ws.webservices
.wsif.providers.soap
.WSIFJmsSender._invoke
 (WSIFJmsSender.java:126)

The limitation also occurs for SOAP over JMS Web Services. If
a Web Service exposed on an application server, using the SOAP
over JMS protocol, has not been invoked, then when a WSIF
client invokes a Web Service using SOAP over JMS, the WSIF Web
Service engine configuration will be registered for all users
in the application server.

Therefore, if a JAX-RPC client invokes the SOAP over JMS Web
Service, a JMS message arrives on the Web Service queue. An MDB
listener bean will be activated to process the message. This
will attempt to locate the Web Service to process the message.
However, because the Web Service engine configuration is now
the WSIF engine configuration, all information regarding SOAP
over JMS Web Service mappings is lost. The JAX-RPC client will
see a message from the application server saying that the target
service cannot be located.
Problem conclusion
WSIF has been changed to register its JMS Transport for only
WSIF clients, without impacting the rest of the application
server. The fix is targetted for WebSphere Application
Server 5.1.1 cumulative fix 4.
