Customizing a Service Control: Declaring Compliance with a WSDL File

This topic describes customizations you can make to a Service control's CTRL file to modify the control's default behavior.

To learn more about controls, see Controls: Using Resources from a Web Service.

# How Service Controls Specify Contract Compliance

A Service control CTRL file typically explicitly declares that it complies with the public contract expressed in a WSDL file. This compliance is declared with the @jws:wsdl tag. The @jws:wsdl tag's file attribute names the WSDL file with which the Service control complies.

The file specified by the @jws:wsdl tag may be placed in line inside the Service control's CTRL file. The WSDL contents are specified as the value of a @jws:define tag. The @jws:wsdl tag's file attribute then refers to #Name instead of an actual filename, where Name is the value of the @jws:define tag's name attribute. The following sample contents of a CTRL file illustrate this arrangement:

    import weblogic.jws.control.ServiceControl;
    /**
     * @jws:location http-url="creditreport/IRS.jws" jms-url="creditreport/IRS.jws"
     * @jws:wsdl file="#IRSWsdl"
     */
    public interface IRSControl extends ServiceControl
    {
        ...
    }
    /**
     @jws:define name="IRSWsdl" value::
          <?xml version=1.0 encoding=utf-8?>
          <definitions ...>
            ...remainder of WSDL here...
          </definitions>
      ::
     */

If a Service control has an associated @jws:wsdl tag, the methods in the Service control's interface must be capable of producing messages that comply with the operations defined in the WSDL file.
