Once you instantiate a service proxy for a remote endpoint, you can invoke its methods as if it were a local object. The calls block until the remote method completes.
If a method is annotated with the OneWay annotation, the call returns immediately. Hide Table of Contents English English. Chapter Create a Service object for the service on which the consumer will invoke operations.
Add a port to the Service object. You append Service to the value of the name property of the WebService annotation. You append Service to the name of the SEI. Creating a Service Object package com. QName; import javax. Specify it in the portName property of the WebService annotation. Append Port to the value of the name property of the WebService annotation. Append Port to the name of the SEI. Adding a Port to a Service Object package com. The wscompile command reads the MyHelloService.
Although this wscompile invocation also creates stubs, the dynamic proxy client does not use these stubs, which are required only by static stub clients.
With the dynamic invocation interface DII , a client can call a remote procedure even if the signature of the remote procedure or the name of the service is unknown until runtime.
In contrast to a static stub or dynamic proxy client, a DII client does not require runtime classes generated by wscompile. However, as you'll see in the following section, the source code for a DII client is more complicated than the code for the other two types of clients.
This example is for advanced users who are familiar with WSDL documents. See Further Information. To get a Service object, the program invokes the createService method of a ServiceFactory object.
The WSDL file specifies this name as follows:. A Call object supports the dynamic invocation of the remote procedures of a service. To get a Call object, the program invokes the Service object's createCall method. To specify the return type, the program invokes the setReturnType method on the Call object. The program designates the method name by invoking the setOperationName method with a QName object that represents sayHello.
To indicate the method parameter, the program invokes the addParameter method on the Call object. The program assigns the parameter value Murphy to a String array params and then executes the invoke method with the String array as an argument.
Unlike the previous client examples, the DII client does not require files generated by wscompile. In the context of UC, you would use this tool as follows:. The -keep option causes wsimport to save the source code for these class files as well, which helps us learn how clients access the Web service, and makes it possible to add client-side handlers for intercepting messages discussed later in this series. You can specify any meaningful name such as client and wsimport will create a package directory with this name, and store the package directory structure underneath.
Along with class files, wsimport stores UC. The former source file's Java interface declares the same methods as Listing 1's UC SEI interface, but with c2F , cm2In , f2C , and in2Cm method names replacing c2f , cm2in , f2c , and in2cm to adhere to a JAXB naming convention where the first letter of each subsequent word in a method name is capitalized. The latter file's class, which is presented in Listing 7, provides a noargument constructor for instantiating this class, and a getUCImplPort method that returns an instance of the generated UC interface; the client executes the Web service's operations on this instance.
