jboss4.0中webservice应用

1. 安装Jboss

2. 将webservice endpoint当成servlet

3. 写一个远端的interface

4. 在eclipse中配置一个external tool:wscompile

4. 写一个config.xml， 然后用JWSDP的JAXRPC中的wscompile生成mapping.xml和wsdl

5. 必须存在4个文件：web.xml,webservices.xml,mapping.xml和.wsdl

6. webservices 中的port name 要和.wsdl中的一致

7. 使用lomboz或jbossIDE deploy



详细实例:


1. create a class


package service;



public class Hello {

public boolean helloDancy(String hello){

System.out.println(hello);

return true;

}


}


2. create corresponding remote interface


package remote;


import java.rmi.Remote;

import java.rmi.RemoteException;


public interface HelloRemote extends Remote {

public boolean helloDancy(String hello) throws RemoteException;

}


3. create web.xml in WEB-INF folder


< ?xml version="1.0" encoding="UTF-8"? >

< web-app version="2.4"

xmlns="http://java.sun.com/xml/ns/j2ee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" >

< servlet >

< servlet-name >helloServlet< /servlet-name >

< servlet-class >service.Hello< /servlet-class >

< /servlet >

< servlet-mapping >

< servlet-name >helloServlet< /servlet-name >

< url-pattern >/hello< /url-pattern >

< /servlet-mapping >

< /web-app >


4. create config.xml


< ?xml version="1.0" encoding="UTF-8"? >

< configuration xmlns="http://java.sun.com/xml/ns/jax-rpc/ri/config" >

< service name="helloservice"

targetNamespace="/hello"

typeNamespace="/hello/types"

packageName="service" >

< interface name="remote.HelloRemote" / >

< /service >

< /configuration >


5. create folder wsdl in WEB-INF/ and run wscompile from jaxrpc folder in sun's jwsdp1.5 package


wscompile -cp output/classes -gen:server -f:documentliteral -mapping jaxrpc-mapping.xml -keep config.xml


-keep: keep the generated source file


6. After executing wscompile.bat, a mapping.xml and helloservice.wsdl are generated


7. create webservice.xml


< ?xml version="1.0" encoding="UTF-8"? >


< webservices xmlns="http://java.sun.com/xml/ns/j2ee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://www.ibm.com/webservices/xsd/j2ee_web_services_1_1.xsd" version="1.1" >


< webservice-description >

< webservice-description-name >hello world< /webservice-description-name >

< wsdl-file >WEB-INF/wsdl/helloservice.wsdl< /wsdl-file >

< jaxrpc-mapping-file >WEB-INF/mapping.xml< /jaxrpc-mapping-file >

< port-component >

< port-component-name >hello-dancy< /port-component-name >

< wsdl-port >HelloRemotePort< /wsdl-port >

< service-endpoint-interface >remote.HelloRemote< /service-endpoint-interface >

< service-impl-bean >

< servlet-link >helloServlet< /servlet-link >

< /service-impl-bean >

< /port-component >

< /webservice-description >

< /webservices >


8. create hello.war and deploy it to jboss4.0.1


9. create test client


public void testHelloDancy() {

try{

String urlstr = "http://w20251-01:8080/hellows/hello?wsdl";


java.net.URL url = new java.net.URL(urlstr);


String ns = "/hello";

QName qname = new QName(ns, "Helloservice");

QName port = new QName(ns, "HelloRemotePort");

QName operation = new QName(ns, "helloDancy");


Service service = new Service();

Call call = (Call)service.createCall();


call.setTargetEndpointAddress( url );

call.setOperationName( operation );

call.addParameter( "String_1", XMLType.XSD_BASE64, ParameterMode.IN);


call.setReturnType( XMLType.XSD_BOOLEAN);

Boolean ret = (Boolean)call.invoke(new Object[]{"hello, Dancy".getBytes()});


} catch(Exception e){

e.printStackTrace();

}



}


10. set the classpath to lead to jars in axis's lib folder


11. customized object which involve byte[] as the input parameter

client code:


public void testHelloDancy() {

try{

String urlstr = "http://w20251-01:8080/hellows/hello?wsdl";


java.net.URL url = new java.net.URL(urlstr);


String ns = "/hello";

QName qname = new QName(ns, "Helloservice");

QName port = new QName(ns, "HelloRemotePort");

QName operation = new QName(ns, "helloDancy");


Service service = new Service();

Call call = (Call)service.createCall();

QName qn = new QName( "/hello/types", "Dto" ); //refer to .wsdd

call.registerTypeMapping(service.Dto.class, qn,

new org.apache.axis.encoding.ser.BeanSerializerFactory(service.Dto.class, qn),

new org.apache.axis.encoding.ser.BeanDeserializerFactory(service.Dto.class, qn));


call.setTargetEndpointAddress( url );

call.setOperationName( operation );

call.addParameter( "arg0", qn, ParameterMode.IN);


call.setReturnType( XMLType.XSD_BOOLEAN);

service.Dto dto = new Dto();

dto.setParam("hello, Dancy".getBytes());

Boolean ret = (Boolean)call.invoke(new Object[]{dto});


} catch(Exception e){

e.printStackTrace();

}
