A web service connector listens for QAnywhere messages sent to a particular address, and makes web service calls when messages arrive. Web service responses are sent back to the originating client as QAnywhere messages. All messages sent to the web services connector should be created using the proxy classes generated by the QAnywhere WSDL compiler.

When running MobiLink with QAnywhere messaging in a server farm environment, only the QAnywhere connectors in the primary server start. If the primary server fails, the QAnywhere connectors are automatically started in the new primary server so that message ordering is preserved while exchanging data in the external messaging system, such as JMS. For more information, see Run the MobiLink server in a server farm.
