An endpoint defines an external destination for an outgoing message through WSO2 ESB. An endpoint may be specified as an address endpoint, WSDL based endpoint, a load balancing endpoint or a fail-over endpoint. The For example, the endpoint for the simple stock quote sample is http://localhost:9000/services/SimpleStockQuoteService.

Configuring endpoints

You can use the Management Console to add, edit, and delete endpoints. You can also enable statistics for Address and WSDL endpoints.

In the XML configuration, the <endpoint> element defines an endpoint in the configuration as follows:

<endpoint [name="string"] [key="string"]>
        address-endpoint | default-endpoint | wsdl-endpoint | load-balanced-endpoint | fail-over-endpoint
</endpoint>

Using named endpoints

You can use the name attribute to create a named endpoint. You can reuse a named endpoint by referencing it in another endpoint using the key attribute. For example, if there is an endpoint named "foo," you can reference the "foo" endpoint in any other endpoint where you want to use "foo" has to be used:

<endpoint key="foo"/>

This approach allows you to reuse existing endpoints in multiple places.

Tracing and handling errors

The endpoints also have a trace attribute, which turns on detailed trace information for messages being sent to the endpoint. These are available in the trace.log file, which is configured in the <PRODUCT_HOME>/repository/conf/log4j.properties file. Setting the trace log level to TRACE will log detailed trace information including message payloads. For information on endpoint states and handling errors, see Endpoint Error Handling.

Endpoints can be added, edited, and deleted. You can also enable statistics for Address and WSDL endpoints.
