You can use the WSDL Editor to import one or more other WSDL files into a WSDL file.
If a WSDL file cannot be imported, then the file and the file's namespace are crossed out in the Add Import dialog box. This situation can happen for the following reasons:
The WSDL file has already been imported.
The WSDL file is the same WSDL file.
The namespace is incompatible with the WSDL file that is doing the import.
The WSDL Editor allows you to import a WSDL file that is located in a different project. For more information, see the "About Cross-Project XML File References" topic in the IDE online help.
