An endpoint defines an external destination for an outgoing message through WSO2 ESB. Typically, the endpoint is the address of a proxy service, which acts as the front end to the actual service. For example, the endpoint for the simple stock quote sample is
For detailed information on each endpoint type available with WSO2 ESB, see WSO2 ESB Endpoints.
In the XML configuration, the <endpoint> element defines an endpoint as follows:
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:
This approach allows you to reuse existing endpoints in multiple places.
Working with endpoints
You can either use the ESB tooling plug-in to create a new endpoint and to import an existing endpoint, or you can manage endpoints via the ESB Management Console. For detailed information on how to work with endpoints, see the following topics:
Tracing and handling errors
Endpoints 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 logs detailed trace information including message payloads. For more information on endpoint states and handling errors, see Endpoint Error Handling.
