Take a look at the simple Java code, we use it as a WSDL service code: //catdto.javapublic class catdto {private long id; private string name; public long getId () {return ID;} public string getname (), PUBLIC STRING GETNAME () {RETURN NAME;} public void setid (long ID) {this.id = ID;} public void setname (String name) {this.name = name;}} // Test.javapublic class test {public string echo (CATDTO CD) {Return "Hello" cd.getName ();}} then look at the WSDL: // Composite type
// Represents a message of a composite type
// porttype Lei Tong
// Binds with the implementation, here SOAP mode
// Used to publish services
