The Call mediator is a content-unaware mediator. |
Enabling mutual SSL in the blocking mode
If you use the Call mediator in the blocking mode (blocking=true), you must enable mutual SSL.
Since the Call mediator is run based on the configuration of the axis2_blocking_client.xml file, its default HTTPs transport sender is org.apache.axis2.transport.http.CommonsHTTPTransportSender. Therefore, the Call mediator does not have access to the required key store to handle mutual SSL. To enable the Call mediator to handle mutual SSL, the following JVM settings should be added to the <ESB_HOME>/bin/wso2server.sh file.

-Djavax.net.ssl.keyStore="$CARBON_HOME/repository/resources/security/wso2carbon.jks" \
-Djavax.net.ssl.keyStorePassword="wso2carbon" \
-Djavax.net.ssl.keyPassword="wso2carbon" \ |

Syntax
...
Select one of the following options to define the endpoint to which the message should be delivered.
| Parameter Name | Description | ||
|---|---|---|---|
| None | Select this option if you do not want to provide an endpoint. The Call mediator will send the message using its wsa:to address. | ||
| Define Inline | If this is selected, the endpoint to which the message should be sent can be included within the Call mediator configuration. Click Add to add the required endpoint. See Adding an Endpoint for further details. | ||
| Pick From Registry | If this is selected, the message can be sent to a pre-defined endpoint which is currently saved as a resource in the registry. Click either Configuration Registry or Governance Registry as relevant to select the required endpoint from the resource tree. | ||
| XPath | If this is selected, the endpoint to which the message should be sent will be derived via an XPath expression. You are required to enter the relevant XPath expression in the text field that appears when this option is selected.
