Java WebService simple use case

First, create a webservice:

 PackageGarfield;ImportJavax.jws.WebService;Importjavax.xml.ws.Endpoint; @WebService Public classMyj6webservice { Publicstring SayHello (String strName) {return"Hello," +strname+ "!"; }         Public Static voidMain (string[] args) {//release WebService, note If prompted: Exception in Thread "main" Com.sun.xml.internal.ws.server.ServerRtException:Server Runtime Error:java.net.BindException:Address already in Use:bind//you need to modify the publish portEndpoint.publish ("Http://localhost:8030/garfield.MyJ6WebService",NewMyj6webservice ()); System.out.println ("WebService was published success!"); }}

Start Tomcat and run, and the system will output: WebService was published success!, which means WebService is started.

You can enter the address in the browser: http://localhost:8030/garfield.MyJ6WebService?wsdl

In the WebService boot state, on the command line, enter:

E:\temp>wsimport-p garfield.garfieldj6wsclient-keep http://localhost:8030/garfield. Myj6webservice? wsdlparsing wsdl...generating code...compiling code ... E:\Temp>

Note that you must correspond to the WebService information you publish!

Then the system will automatically generate the relevant interface files, as follows:

Create a new Java project, introduce the output file, and then build the test class:

 Packagexxh;Importgarfield.garfieldj6wsclient.*; Public classWebClient {/**           * @paramargs*/           Public Static voidMain (string[] args) {//Create a Client service objectMyj6webservice Myj6ws =NewMyj6webserviceservice (). Getmyj6webserviceport (); //Call the service method and get the method return valueString strtest = Myj6ws.sayhello ("Garfield"); //The return value of the print serviceSystem.out.println (strtest); }   }

Under WebService run, run the client test program, output:

Hello, garfield!.
