JAX – WS – 10 – wsimport
Merhaba arkadaslar
Bu bolumde wsimport tool’unu inceleyecegiz.
wsimport ile wsdl(web service definition language) dosyalarini parse edebiliriz, ilgili JAX-WS /SOAP service’ni kullanmak icin gerekli .java dosyalarini otomatik olarak olusturabiliriz.
You use the wsimport command to generate Java API for XML Web Services (JAX-WS) portable artifacts.
https://docs.oracle.com/javase/9/tools/wsimport.htm#JSWOR740
Oncelikle ilk ornegimizi tekrar kullanalim. Bu ornegimizde basit bir JAX-WS ornegi uygulamistik.
http://www.injavawetrust.com/jax-ws-02-simple-jax-ws-implementation/
Projeyi 8888 portunda publish etmistik. Tekrar ornegimizi calistiralim ve basarili sekilde wsdl yapisini gorelim.
http://localhost:8888/injavawetrust/hello.jaxws?wsdl
Simdi de command line’ da wsimport komutunu kullanalim.
Dosyalari ornek olarak Desktop/wsimport.example klasorunde olusturacagim.
wsimport -keep -verbose http://localhost:8888/injavawetrust/hello.jaxws?wsdl
Her sey yolundaysa .class ve .java dosyalarimiz basarili sekilde olusacaktir. (-keep) parametresini kullanmazsak sadece .class dosyalari olusur)
-verbose parametresi compiler’in mesajlarini gosterecektir.
-verbose Displays compiler messages. Output messages about what the compiler is doing
Diger parametreleri de kullanabiliriz;
-d parametresi ile dosyalarimizin olusacagi output folder’i verebiliriz.
-p parametresi ile dosyalarimizin ait oldugu package bilgisini verebiliriz.
-d directory Specifies where to place generated output files. -p name Specifies a target package name to override the WSDL file and schema binding customizations, and the default algorithm defined in the specification.
wsimport -verbose -d mydir -p mypackage http://localhost:8888/injavawetrust/hello.jaxws?wsdl
mydir folder’i altinda , mypackage paket yapisinda ilgili dosyalarimiz olusacaktir.
Ilk olusturdugumuz dosyalari kullanabiliriz.

Test Client
Simdi de Client Test sinifimizi yazalim.
MessageWriterImplService objesi uzerinden getMessageWriterImplPort metodunu kullabiliriz.
MessageWriter objesi uzerinden getWelcomeMessage’ni test edebiliriz.
package client;
import injavawetrust.ws.service.MessageWriter;
import injavawetrust.ws.service.MessageWriterImplService;
public class ClientTest {
public static void main(String[] args) {
MessageWriterImplService service = new MessageWriterImplService();
MessageWriter messageWriter = service.getMessageWriterImplPort();
String message = messageWriter.getWelcomeMessage("levent", "erguder");
System.out.println(message);
}
}
// 1) run , injavawetrust.hello.jaxws project WebServicePublisher.java
Ornegi calistirdigimizda;
Welcome , levent erguder. This message is sent by MessageWriterImpl#getWelcomeMessage.
Tabiki diger projemizdeki WebServicePublisher sinfi hali hazirda calisiyor olmali. Aksi durumda connection refused hatasi aliriz.
