A binder is a webMethods term for a collection of related definitions and specifications for a particular port. The binder is a container for the endpoint address, WSDL binding element, transport protocol, and communication protocol information. Designer creates at least one binder when it generates the web service descriptor based on the data in the WSDL or IS service. The Binders tab displays the binders defined for a web service descriptor.

You can add new binder definitions to a service first provider web service descriptor. Binders cannot be added to a WSDL first provider web service descriptor or a consumer web service descriptor.

You can define a separate binder for each combination of endpoint address and protocol information that you want the service first provider web service descriptor to support.
