When you save an IEP Module project, IEP generates a Web Services Description Language (WSDL) document for each event processor. The WSDL documents contain the endpoints for the event processors.
By default, the WSDL documents include concrete information (that is, bindings and services). You might need to manually update the default settings for any binding and service. For example, the default file directory is a Windows path, which would not work correctly on a UNIX system. If you manually update the WSDL document and then save the IEP Module project again, the changes that you made to the WSDL document are overwritten.
You can configure IEP to generate abstract WSDL documents instead. The bindings and services are not included. With this approach, you can define the bindings and services by using the Composite Application Service Assembly (CASA) Editor. These bindings and services are not affected by subsequent changes to the IEP Module project.
