The Correlation Service will be removed and should not be used.
 Technote (troubleshooting)
 
Problem(Abstract)
The Correlation Service which is packaged as part of WSIF is superfluous and there is no need for anyone to use it. This function will be removed from WSAS 5.0.x as we move into 5.1
 
Resolving the problem
WSIF supports correlation between the request and response in the asynchronous request-response case. When the request is sent, the WSIFOperation is serialized into the WSIFCorrelationService. The executeRequestResponseAsync methods returns a WSIFCorrelationId object which identifies the serialized WSIFOperation. The client listener can use this to match a response to a particular request.

The correlation service is located with the getCorrelationService() method of the WSIFCorrelationServiceLocator class in the org.apache.wsif.utils package.

In a managed container a default correlation service is defined in the default JNDI namespace using the name: java:comp/wsif/WSIFCorrelationService . If this is not available, then WSIF will use the WSIFDefaultCorrelationService.


The correlation service is superfluous, there is no need for people to use it, and this function will be removed from WSAS V5.0.1. The InfoCenter will be updated to remove all references to this function from WSAS V5.1. A documentation change may be made to indicate that the correlation service is not to be used/installed.
