JavaTM Web Services Developer Pack 2.0 (4)

JAXWS20 First Sample

 

 

Sample Program : Server

 

 

Web Service Business Class을 작성한다.

 

package fromjava.server;     public class AddNumbersException extends Exception {       private static final long serialVersionUID = 1L;       String detail;             public AddNumbersException (String message, String detail) {           super (message);           this.detail = detail;       }             public String getDetail () {           return detail;       }   }

 

package fromjava.server;   import javax.xml.ws.Endpoint;     public class AddWebservice {             public static void main (String[] args) throws Exception {           Endpoint.publish (               "http://localhost:8080/jaxws20test/addnumbers",               new AddNumbersImpl ());       }   }

 

package fromjava.server; import javax.jws.WebService; @WebService public class AddNumbersImpl {      public int addNumbers(int number1, int number2) throws AddNumbersException {         if (number1 < 0 || number2 < 0) {             throw new AddNumbersException("Negative number cant be added!",                 "Numbers: " + number1 + ", " + number2);         }         return number1 + number2;     } }

 

Business Class Compile

 

set path=%path%;E:CommonLibjwsdp-2.0jaxwsbin;     set classpath=%classpath%;E:CommonLibjwsdp-2.0jaxwslibjaxws-api.jar;E:CommonLibjwsdp-2.0jaxwslibjaxws-rt.jar;E:CommonLibjwsdp-2.0jaxwslibjaxws-tools.jar;E:CommonLibjwsdp-2.0jaxwslibjsr181-api.jar;E:CommonLibjwsdp-2.0jaxwslibjsr250-api.jar;E:CommonLibjwsdp-2.0jaxblibjaxb-api.jar;E:CommonLibjwsdp-2.0jaxblibjaxb-impl.jar;E:CommonLibjwsdp-2.0jaxblibjaxb-xjc.jar;E:CommonLibjwsdp-2.0jaxblibjaxb1-impl.jar;     javac -d  . fromjavaserver*.java

 

Generate Portable Artifacts

 

wsgen -cp . -keep -d . -wsdl fromjava.server.AddNumbersImpl

 

Create a WAR file to deploy

 

 

web.xml 작성

 

<?xml version="1.0" encoding="UTF-8"?>   <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/j2ee/dtds/web-app_2_3.dtd">   <web-app>     <display-name>fromjava</display-name>     <description>fromjava</description>     <listener>       <listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>     </listener>     <servlet>       <servlet-name>fromjava</servlet-name>       <display-name>fromjava</display-name>       <description>JAX-WS endpoint - fromjava</description>       <servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>       <load-on-startup>1</load-on-startup>     </servlet>     <servlet-mapping>       <servlet-name>fromjava</servlet-name>       <url-pattern>/addnumbers</url-pattern>     </servlet-mapping>     <session-config>       <session-timeout>60</session-timeout>     </session-config>   </web-app>

 

 

sun-jaxws.xml 작성

 

<?xml version="1.0" encoding="UTF-8"?>   <endpoints xmlns='http://java.sun.com/xml/ns/jax-ws/ri/runtime' version='2.0'>       <endpoint           name='fromjava'           implementation='fromjava.server.AddNumbersImpl'           url-pattern='/addnumbers'/>   </endpoints>

이 파일은 JAX-RPC 1.x 에서 “jaxrpc-ri.xml” 파일과 유사한 파일이다.

 

 

WAR 작성 및 배포

 

l        WEB-INFclasses : Business Class와 생성한 Artifacts 클래스

 

l        WEB-INFwsdl : 생성된 wsdl, xsd 파일(AddNumbersImplService.wsdl, AddNumbersImplService_schema1.xsd)

 

l        WEB-INF : web.xml, sun-jaxws.xml 파일

 

l        위 파일들을 위치 시킨 후 JWSDP2.0 과 같이 설치한 TomcatForJWSDP에 배포한다.

 

 

Sample Program : Client

 

 

Generate a Service Endpoint Interface

 

wsimport -d . -p addumber.client.gen http://localhost:8080/jaxws20test/addnumbers?wsdl

wsimport 명령어는 JAXWSbin에 있다. http://localhost:8080/jaxws20test/addnumbers?wsdl

 

부분은 서버 모듈이 설치되어 있는 WAS의 실제 접근 URL이다. 위 명령어로 생성된 Service Endpoint Interface을 이용하여 Client Program을 작성한다.

 

 

Client Program

 

package fromjava.client;     import addumber.client.gen.*;   import addumber.client.gen.AddNumbersImpl;       public class AddNumbersClient {       public static void main (String[] args) {           try {               AddNumbersImpl port = new AddNumbersImplService().getAddNumbersImplPort();                             int number1 = 10;               int number2 = 20;                             System.out.printf ("Invoking addNumbers(%d, %d)n", number1, number2);               int result = port.addNumbers (number1, number2);               System.out.printf ("The result of adding %d and %d is %d.nn", number1, number2, result);                             number1 = -10;               System.out.printf ("Invoking addNumbers(%d, %d)n", number1, number2);               result = port.addNumbers (number1, number2);               System.out.printf ("The result of adding %d and %d is %d.n", number1, number2, result);           } catch (AddNumbersException_Exception ex) {               System.out.printf ("Caught AddNumbersException_Exception: %sn", ex.getFaultInfo ().getDetail ());           }       }   }

 

Compile and Run

 

Compile 및 실행시에 다음 library가 Classpath에 잡혀 있어야 한다. 특히 SAAJ은 JWSDP2.0에 포함되어 있는 SAAJ 1.3 버전이 어야 한다.
