Saving Logical Ports 

Use

Logical ports information is gathered and saved. This information is what makes the proxy usage possible. It is used for the stub initialization and also can carry additional client settings. These additional adjustments are referred to as Web service features. Logical ports are essential for support of the SAP client programming model. They allow for carrying proxy configuration data, without having a generated stub and also before the client is actually deployed. When using standard WSDLs, logical port structures reflect WSDLs service tag contents (that is, they contain the target-address, and relation to a WSDL binding).

The logical ports are saved in an XML format and they allow the user to define and change the Web services endpoints, client proxy settings and security settings without writing a single line of code or regenerating anything. When using SAP WSDLs (SAP specific extended WSDLs), this is the place where feature information is saved. By default, this information is saved in lports.xml file inside the root proxy package (this is configurable, through the ProxyGeneratorConfig).
