Subject [jira] Commented: (SYNAPSE-577) WSDL Endpoints Stored in the Registry Cannot be Used
Date Sat, 05 Sep 2009 18:35:57 GMT

    [ https://issues.apache.org/jira/browse/SYNAPSE-577?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12751779#action_12751779
] 

Supun Kamburugamuva commented on SYNAPSE-577:
---------------------------------------------

I also think just checking the weather the endpoint is initialized is not the right way to
solve this. Right way to solve this is to call the init methods when we fetch the endpoint
from the registry.

> 1. Define a valid registry provider in the Synapse configuration
> 2. Store a WSDL endpoint definition in the registry
> 3. Create a proxy service which refers to the WSDL endpoint in the registry
> 4. Start Synapse and send a message to the proxy service
> Message will be dispatched to the back end service, but Synapse will fail to route the
response back. The following NPE occurs.

> This is because the endpoint returned by the AbstractRegistry is not initialized and
hence does not have an associated EndpointContext.
