文章中的WS服务使得这个服务可以在DotNet环境中调用.

文件清单:

SEI接口类IImage.java,实现SEI接口的类IIMageImpl.java,描述文件信息的值类型类FileInfo.java,Web应用部署描述文件web.xml,WS发布配置文件jaxrpc-ri.xml,WS编译配置文件config-interface.xml,构建客户端桩的config-wsdl.xml,构建文件builder.xml

客户端测试类:Form1.cs.

本例是从WSDL开始的,因此我们要有一个WSDL文件.第一步就是得到这个文件.

(一) 得到WSDL文件.

为达到互操作要求,这个文件的描述必须是文档样式的绑定,文字格式的编码.为得到此文件,首先介绍构建文件builder.xml:

   <classpath refid="compile.classpath" />
  </wscompile>
 </target>
</project>

在这个构建文件中的build任务中, features的值指定为"wsi,documentliteral",这个任务需要的config-interface.xml:

<?xml version="1.0" encoding="UTF-8"?>
<configuration xmlns="http://java.sun.com/xml/ns/jax-rpc/ri/config">
 <service name="BinaryService" targetNamespace="urn:binary"
  typeNamespace="urn:binary" packageName="com.binary">
  <interface name="com.bin.IImage"
   servantName="com.bin.ImageImpl" />
 </service>
</configuration>

这个文件的需要的com.bin.IImage SEI接口文件及其实现文件com.bin.ImageImpl:

public interface IImage extends Remote {
 //public DataHandler fetchImg(String sn) throws RemoteException;
 //public DataHandler[] fetchImgs(String[] sn) throws RemoteException;
 public SOAPMessage construcMsg(String[] fn) throws RemoteException;
 public byte[] fetchImage(String sn) throws RemoteException;
 public FileInfo[] fetchFileList() throws java.rmi.RemoteException;
 public FileInfo getFileList(String fn) throws java.rmi.RemoteException;
}

DataHandler,ArrayList属于java的类当然不允许出现在接口中了,因为C#不认识这些类,FileInfo值类型类倒支持,因为这个类没有方法,而且数据类型都是可以用SOAP来表示的,C#是可以理解的.

实现文件,注意实现的方法是空方法.

public class ImageImpl implements IImage {
 public SOAPMessage construcMsg(String[] fn) throws RemoteException {
   return null;
  }
 public byte[] fetchImage(String sn) throws RemoteException{
  return null;
 }
 public FileInfo[] fetchFileList() throws java.rmi.RemoteException{
  return null;
 }
  public FileInfo getFileList(String fn) throws RemoteException {
  return null;
  }
}

到这里,为互操作所做的修改只是在 features的值指定为"wsi,documentliteral",其它地方没有修改包括config-interface.xml接口配置文件.

通过执行这个任务,可以得到我们想要的BinaryService.wsdl文件.位于nonclass文件夹中,把它移动到conf中.

(二) 构造Web服务

在这个conf文件夹中除了有BinaryService.wsdl外,还有两个文件:

config-client.xml,用来根据WSDL文件生成客户端访问服务所需要的制品.

<?xml version="1.0" encoding="UTF-8"?>
<configuration xmlns="http://java.sun.com/xml/ns/jax-rpc/ri/config">
 <wsdl
  location="http://localhost:8080/netservice/binary?WSDL"
  packageName="wsidotnet" />
</configuration>

config-server.xml则用来根据BinaryService.wsdl生成服务器端制品,包括重新生成的SEI接口文件,我们将利用这个文件编写服务实现,而不是前面提到的com.bin.IImage SEI接口文件及其实现文件com.bin.ImageImpl:

<?xml version="1.0" encoding="UTF-8"?>
<configuration xmlns="http://java.sun.com/xml/ns/jax-rpc/ri/config">
 <wsdl location="web-inf/conf/BinaryService.wsdl"
  packageName="wsidotnet" />
</configuration>

到目前为止,还有两个文件没有提供:

jaxrpc-ri.xml:

<?xml version="1.0" encoding="UTF-8"?>
<webServices xmlns="http://java.sun.com/xml/ns/jax-rpc/ri/dd"
 version="1.0"
 targetNamespaceBase="http://java.sun.com/xml/ns/jax-rpc/wsi/wsdl"
 typeNamespaceBase="http://java.sun.com/xml/ns/jax-rpc/wsi/types"
 urlPatternBase="/ws">

 <endpoint name="ImageBinaryService" displayName="Stock Example"
  description="Stock Example Web Service endpoint"
  interface="wsidotnet.IImage" implementation="wsidotnet.IImage_Impl"
  model="/WEB-INF/model.xml.gz" />
 <endpointMapping endpointName="ImageBinaryService" urlPattern="/binary" />
</webServices>

web.xml文件:

<?xml version="1.0" encoding="UTF-8"?>
<web-app 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"
 version="2.4">
 <context-param>
  <param-name>BinaryPath</param-name>
  <param-value>更改成你的本地文件路径</param-value>
 </context-param>
 <welcome-file-list>
  <welcome-file>index.htm</welcome-file>
  <welcome-file>index.jsp</welcome-file>
  <welcome-file>index.jws</welcome-file>
 </welcome-file-list>
</web-app>

下面就是构建过程,首先,执行wsi server service得到服务器端的java制品,包括重新生成的SEI,wscompile还生成了一个实现文件IImage_Impl ,后面要修改这个类,在其中加入有用的方法.

wsidotnet.IImage清单:

package wsidotnet;

public interface IImage extends java.rmi.Remote {
    public wsidotnet.ConstrucMsgResponse construcMsg(wsidotnet.ConstrucMsg parameters) throws
         java.rmi.RemoteException;
    public wsidotnet.FetchFileListResponse fetchFileList(wsidotnet.FetchFileList parameters) throws
         java.rmi.RemoteException;
    public wsidotnet.FetchImageResponse fetchImage(wsidotnet.FetchImage parameters) throws
         java.rmi.RemoteException;
    public wsidotnet.GetFileListResponse getFileList(wsidotnet.GetFileList parameters) throws
         java.rmi.RemoteException;
}

和前面的com.bin.IImage接口相比很不同了.因为采用文档样式的绑定,所以这里就产生了所谓的包装类了.

实现文件为:

package wsidotnet;

import java.io.File;
import java.io.FileInputStream;
import java.nio.MappedByteBuffer;
import java.nio.channels.FileChannel;
import java.util.Calendar;
import java.util.Date;

import javax.servlet.ServletContext;
import javax.xml.rpc.ServiceException;
import javax.xml.rpc.server.ServiceLifecycle;
import javax.xml.rpc.server.ServletEndpointContext;

public class IImage_Impl implements wsidotnet.IImage, java.rmi.Remote,ServiceLifecycle {
 ServletEndpointContext servletEndpointContext = null;

 String binarypath = "";

 ServletContext servletContext = null;
 
    public wsidotnet.ConstrucMsgResponse construcMsg(wsidotnet.ConstrucMsg parameters) throws
         java.rmi.RemoteException {
       
        wsidotnet.ConstrucMsgResponse _retVal = null;
        return _retVal;
    }
    public wsidotnet.FetchFileListResponse fetchFileList(wsidotnet.FetchFileList parameters) throws
         java.rmi.RemoteException {
        wsidotnet.FetchFileListResponse _retVal = new FetchFileListResponse();
        _retVal.setResult(fetchFileList());
        return _retVal;
    }
    public wsidotnet.FetchImageResponse fetchImage(wsidotnet.FetchImage parameters) throws
         java.rmi.RemoteException {
        wsidotnet.FetchImageResponse _retVal = new FetchImageResponse();
        _retVal.setResult(fetchImage(parameters.getString_1()));
        return _retVal;
    }

    public wsidotnet.GetFileListResponse getFileList(wsidotnet.GetFileList parameters) throws
         java.rmi.RemoteException {
       
        wsidotnet.GetFileListResponse _retVal = null;
        return _retVal;
    }
 private FileInfo[] fetchFileList() {
  File file = new File(this.binarypath);
  System.out.println(this.binarypath);
  File[] c = file.listFiles();
  FileInfo[] fis = new FileInfo[c.length];
  for (int i = 0; i < c.length; i++) {
   FileInfo fi = new FileInfo();
   fi.setIsdir(c[i].isDirectory());
   fi.setFilename(c[i].getName());
   fi.setFilelength(c[i].length());
   fi.setFilepath(c[i].getAbsolutePath());
   Calendar cal=Calendar.getInstance();
   cal.setTime(new Date(c[i].lastModified()));
   fi.setCreatedate(cal);
   fis[i] = fi;
  }
  return fis;
 }

 private byte[] fetchImage(String sn) {
  File file = new File(sn);
  byte[] b=null;
  MappedByteBuffer buffer = null;
  try {
   FileInputStream is = new FileInputStream(file);
   b=new byte[(int)file.length()];
   is.read(b,0,(int)file.length());
   /*
   FileChannel fc = is.getChannel();
   buffer = fc.map(FileChannel.MapMode.READ_ONLY, 0, file.length());
   buffer.get
   */
  } catch (Exception ex) {
   System.out.println(ex);
  }
  //return buffer.array();
  return b;
 }

 public void destroy() {
  // TODO Auto-generated method stub
  servletEndpointContext = null;
  servletContext = null;
 }
 public void init(Object arg0) throws ServiceException {
  // TODO Auto-generated method stub
  servletEndpointContext = (ServletEndpointContext) arg0;
  servletContext = servletEndpointContext.getServletContext();
  binarypath = servletContext.getInitParameter("BinaryPath");
 }
}

这里展示的实现类,已经过修改,让它扩展了ServiceLifecycle接口,以便运行环境送给它小金豆.这里就是获得了文件路径.此外,还提供了两个私有方法:fetchImage,fetchFileList用于具体执行功能,这里也可以把这两个方法移动到一个新类,然后IImage_Impl使用这个新类,使IImage_Impl类变成调用者对外部类的适配器,这样就形成了一个适配器模式.

完成以上修改后,继续执行Ant 任务:create-war,deploy后,得到了可供发布的netservice.war进行发布.本例使用Tomcat5,检查http://localhost:8080/netservice/binary?WSDL是否装入.
发布成功后,用VS新建一个C#项目,通过这个地址http://localhost:8080/netservice/binary?WSDL引用这个服务,然后编写以下类:
