The WSDL Customization panel of the Web Service Attributes Editor is available to JAX-WS (Java EE 5) web services and clients that are created from WSDL. In these scenarios, wsimport is invoked to generate the JAX-WS artifacts. By default, wsimport follows the binding rules specified by the JAX-WS specification. You use the WSDL Customization panel to customize the behaviour of wsimport when generating these artifacts.
You access the WSDL Customization panel of the Web Service Attributes Editor from the Projects window. Right-click the node representing a "from WSDL" artifact and then choose Edit Web Service Attributes. For example, for web service clients, expand the Web Service References node, right-click a node representing a web service client, and choose Edit Web Service Attributes. The editor appears. Choose the WSDL Customization tab and the panel opens.
Use the External Bindings section to add user-created customization files. You may add multiple JAXB customization files, JAXWS customization files, or both. If you add a JAXWS customization file, the wsdlLocation attribute will automatically be changed to point to the correct location of the WSDL file in the project. If you add a JAXB customization file, you will need to manually change the schemaLocation attribute to point to the correct schema location, which is relative to the WSDL file, in the project.
