VB.NET客户端调用Axis的Java Web Service实现文件上传

1. Java Web Service类DocumentFileManagement：

import java.io.*;
/**
* @author tyrone
*
*/

public class DocumentFileManagement {

//文件名， 文件内容，保存到d盘根目录
public String saveFile(String filename,byte[] contents){
if (filename==null || contents==null)
return "null";
String filepath="d:\\";
File fp=new File(filepath+filename);
try{
BufferedOutputStream op=new BufferedOutputStream(new FileOutputStream(fp));
op.write(contents,0,contents.length);
op.flush();
op.close();
if(fp.exists())
return fp.getAbsolutePath();
else
return "failure to create";
}catch(java.io.IOException e){
return e.getMessage();
}
}
}

2 部署到Axis服务器：

生成depoy.wsdd

<deployment xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<service name="DocumentFileManagement" provider="java:RPC">
<parameter name="className" value="DocumentFileManagement"/>
<parameter name="allowedMethods" value="saveFile"/>
</service>
</deployment>

命令行：/>AdminClient depoy.wsdd

3. copy DocumentFileManagement .class 到 axis\WEB-INF\classes目录

4. 用.NET的wsdl.exe生成VB.NET客户端类

命令行:/>wsdl /language:vb http://localhost:8080/axis/services/DocumentFileManagement?wsdl

生成DocumentFileManagementService.vb

5. 调用DocumentFileManagementService.vb
Module Module1

Sub Main()
Dim ws As New DocumentFileManagementService
Dim result As String

'connect colimas web service
Dim contents As Byte
Dim fp As System.IO.File
Dim str As System.IO.FileStream
Dim fpname As String

Dim i As Integer

'上传的文件名
fpname = "StevenMills.doc"
str = fp.Open(fpname, 3)
Dim content(str.Length) As Byte
For i = 0 To str.Length - 1
content(i) = str.ReadByte()
Next
Try

'调用WebService的方法
result = ws.saveFile(fpname, content)
Console.Write(result)
Catch ex As Exception
Console.Write(ex.Message())
End Try

End Sub

End Module
