升级到 JDK 5.0 Update 1 or 2 定制部署 WebServices - Axis 终于正常了!
http://blog.csdn.net/playyuer/archive/2005/03/01/306360.aspx

为了使程序及环境简洁,本文均使用最简陋的 NotePad 编写程序或配置环境,命令行编译程序!
不使用任何集成开发环境(IDE)!

Sever Side:
采用 Resin/Tomcat + Axis 来部署 java Web Service。
1.首先确认 Windows 系统中安装(不一定要安装,解压到目录即可)了如下软件:
J2SE(TM) Development Kit 5.0 Update 4 (JDK 5.0 Update 4):
http://java.sun.com/j2se/1.5.0/download.jsp

  Web Application Server: Resin/Tomcat 二者有其一即可:
  Resin v2.1.16:
  http://www.caucho.com/download/resin-2.1.16.zip
  Tomcat v5.5.9:
  http://apache.justdn.org/jakarta/tomcat-5/v5.5.9/bin/jakarta-tomcat-5.5.9.zip
  下载后解压到某目录,如:
  D:\dotNet.J2EE\resin-2.1.16\
  或
  D:\dotNet.J2EE\jakarta-tomcat-5.5.9\

  Web Services - Axis
  http://apache.freelamp.com/ws/axis/1_2_1/axis-bin-1_2_1.zip
  下载后解压到某目录,如:
  D:\dotNet.J2EE\axis-1_2_1\
  然后将该目录下的 webapps 下的 axis 子目录,复制到:
  D:\dotNet.J2EE\resin-2.1.16\webapps\
  或
  D:\dotNet.J2EE\jakarta-tomcat-5.5.9\webapps\
  即生成如下路径:
  D:\dotNet.J2EE\resin-2.1.16\webapps\axis\
  或
  D:\dotNet.J2EE\jakarta-tomcat-5.5.9\webapps\axis\

  至此就具备运行 Axis 的基本条件了:
  先做一下 Java Web Application Server 端口配置到 1080:
  (如果你的端口不冲突,可以跳过此步)
  Resin:
  D:\Resin\resin-2.1.16\conf\resin.conf  用 IE 访问:
  http://localhost:1080/axis/
  应该看到:
  Apache-AXIS 主页
  点击超链接:
  Validation - Validate the local installation's configuration
  see below if this does not work.
  访问页面:
  http://localhost:1080/axis/happyaxis.jsp
  就可以检测当前环境是否满足运行 Apache-AXIS。
  根据页面提示下载到所有 zip 文件:
  http://192.18.97.238/ECom/EComTicketServlet/BEGIN8656005BAB2BAA9A4B1688FB7D4AF765/-2147483648/972910143/1/359918/359906/972910143/2ts+/westCoastFSEND/7017-jaf-1.0.2-oth-JPR/7017-jaf-1.0.2-oth-JPR:1/jaf-1_0_2-upd2.zip
  http://192.18.97.186/ECom/EComTicketServlet/BEGIN87ACAEFABC9A644DBEC89773E476BF24/-2147483648/972928407/1/540782/540770/972928407/2ts+/westCoastFSEND/javamail-1_3_2-oth-JPR/javamail-1_3_2-oth-JPR:1/javamail-1_3_2-upd.zip
  http://xml.apache.org/security/dist/java-library/xml-security-bin-1_2_1.zip
  各自解压后得到所需所有 jar 包文件:
  activation.jar
  axis-ant.jar
  axis.jar
  commons-discovery-0.2.jar
  commons-logging-1.0.4.jar
  commons-logging-api.jar
  commons-logging.jar
  imap.jar
  jaxrpc.jar
  log4j-1.2.8.jar
  mail.jar
  mailapi.jar
  pop3.jar
  saaj.jar
  smtp.jar
  tt.txt
  wsdl4j-1.5.1.jar
  xalan.jar
  xercesImpl.jar
  xml-apis.jar
  xmlsec-1.2.1.jar
  xmlsecSamples-1.2.1.jar
  xmlsecTests-1.2.1.jar
  将这些文件全部复制到如下目录:
  D:\dotNet.J2EE\resin-2.1.16\webapps\axis\WEB-INF\lib
  或
  D:\dotNet.J2EE\jakarta-tomcat-5.5.9\webapps\axis\WEB-INF\lib
  再次访问:
  http://localhost:1080/axis/happyaxis.jsp
  以验证是否完全满足运行 Apache-AXIS 的环境,
  如无错误就说明已经配置好服务器了!

Tomcat:
D:\dotNet.J2EE\jakarta-tomcat-5.5.9\conf

<Connector port="1080" maxHttpHeaderSize="8192"

maxThreads="150" minSpareThreads="25" maxSpareThreads="75"

enableLookups="false" redirectPort="8443" acceptCount="100"

connectionTimeout="20000" disableUploadTimeout="true" />

   然后,启动 Java Web Application Server:
  Resin:
  D:\dotNet.J2EE\resin-2.1.16\bin\httpd.exe
  Tomcat:
  (启动 Tomcat 要预先配置 JAVA_HOME 环境变量)
  D:\dotNet.J2EE\jakarta-tomcat-5.5.9\bin\start.bat

2.编写 Java Web Service 程序:
  其实实现 Web Service 的 Java 类没啥特殊的,
  下面程序就是:
  实现支持文件分块多点异步上传的 Java Web Services (Server Side)//=========================================================================

Class1.jws

Class1.java

javac Class1.java

java -cp %axis_lib%;%classpath%;. org.apache.axis.client.AdminClient deploy.wsdd -p1080

import java.io.*;

import java.lang.*;

public class Class1

{

public static void main(String[] args)

{

System.out.println("Hello World!");

}

public String SayHelloTo(String Who)

{

return "你好: " + Who;

}

public String SayHelloToo(String Who)

{

return "你好: " + Who;

}

public String UploadFileBytes(byte[] Bytes,String FileName)

throws Exception

{

return UploadFileChunkBytes(Bytes, 0, FileName);

}

public String UploadFileChunkBytes(byte[] Bytes,int Position,String FileName)

throws Exception

{

//"d:\\Server\\Upload\\" 为服务器端路径

String ServerPath = "d:\\Server\\Upload\\";

java.io.RandomAccessFile raf = new java.io.RandomAccessFile(ServerPath + FileName,"rws");

raf.skipBytes(Position);

raf.write(Bytes);

//该 Bytes 的字节要写到服务器端相应文件的从 Position 开始的字节

raf.close();

raf = null;

System.gc();

return FileName + " 文件块: 位置[" + Position + "," + (Position + Bytes.length) + "] 大小(" + Bytes.length + ") 上传成功!";

}

public String CreateBlankFile(String FileName,int Length) //建议由客户端同步调用

throws Exception

{

//"d:\\Server\\Upload\\" 为服务器端路径

String ServerPath = "d:\\Server\\Upload\\";

FileOutputStream fos = new FileOutputStream(ServerPath + FileName);

fos.write(new byte[Length], 0, Length);

fos.close();

fos = null;

System.gc() ;

return FileName + " (" + Length + ") 空白文件已经创建!";

}

public byte[] DownloadFileBytes(String FileName)

throws Exception

{

File f = new File(FileName);

FileInputStream fis = new FileInputStream(f);

int i = (int) f.length();

byte[] b = new byte[i];

fis.read(b,0,i);

fis.close();

fis = null;

f = null;

System.gc() ;

return b;

}

//=========================================================================

  如果上面程序存为: Class1.jws 文件,直接复制到:
  D:\dotNet.J2EE\resin-2.1.16\webapps\axis\Class1.jws
  或
  D:\dotNet.J2EE\jakarta-tomcat-5.5.9\webapps\axis\Class1.jws
  即可通过 IE 直接访问如下 URL 地址:
  http://localhost:1080/axis/Class1.jws
  这就如同 .Net Web Service .asmx 的前代码方式

  接下来着重介绍一下定制部署 Java Web Service
  将上面程序存为: Class1.java 文件,并用如下命令行编译:
  javac.exe Class1.java
  生成的 Class1.class 文件复制到:
  D:\dotNet.J2EE\resin-2.1.16\webapps\axis\WEB-INF\classes\Class1.class
  或
  D:\dotNet.J2EE\jakarta-tomcat-5.5.9\webapps\axis\WEB-INF\classes\Class1.class
  编写部署文件
  deploy.wsdd (undeploy.wsdd):  在通过如下命令行部署该 Web Service ,此时 Java Web Application Server 应已经运行:
    java -cp %axis_lib%;%classpath%;. org.apache.axis.client.AdminClient deploy.wsdd -p1080
  如果部署成功屏幕将会输出:

</service>

</deployment>

Processing file deploy.wsdd

<Admin>Done processing</Admin>

  如果在 Resin 上部署失败,可在:
  D:\Resin\resin-2.1.16\conf\resin.conf
  中:

<war-dir id='webapps'/>

后添加如下配置:

<system-property javax.xml.transform.TransformerFactory = "org.apache.xalan.processor.TransformerFactoryImpl" />

<system-property javax.xml.parsers.DocumentBuilderFactory = "org.apache.xerces.jaxp.DocumentBuilderFactoryImpl" />

<system-property javax.xml.parsers.SAXParserFactory = "org.apache.xerces.jaxp.SAXParserFactoryImpl" />

<system-property org.xml.sax.driver = "org.apache.xerces.parsers.SAXParser" />

  Tomcat 上暂没发现上面部署失败问题!
  部署成功后,在下面文件:
  D:\dotNet.J2EE\resin-2.1.16\webapps\axis\WEB-INF\server-config.wsdd
  或
  D:\dotNet.J2EE\jakarta-tomcat-5.5.9\webapps\axis\WEB-INF\server-config.wsdd
  中,已经被自动添加如下配置:

</service>

  当然也可以手工直接填写配置 server-config.wsdd 而不使用命令行工具!
  至此如不出意外 java Web Service 已经部署完毕!

Client Side:
  http://localhost:1080/axis/services/Class1Service?wsdl
  已经可以正常访问!
java Client:
  还可以用解压 axis-bin-1_2_1.zip 后:
  D:\dotNet.J2EE\axis-bin-1_2_1\axis-1_2_1\samples\client\DynamicInvoker.java
  用如下命令行编译后:
  javac -cp %classpath%;%axis_lib%;. -Xlint:unchecked DynamicInvoker.java
  生成 DynamicInvoker.class,
  再如下命令行运行:
  java -cp %axis_lib%;%classpath%;. DynamicInvoker http://localhost:1080/axis/services/Class1Service?wsdl SayHelloTo 小平
  其中 %axis_lib% 为环境变量! 其中 %classpath% 为环境变量!
  测试如果正常则输出:

Reading WSDL document from 'http://localhost:1080/axis/services/Class1Service?wsdl'

Preparing Axis dynamic invocation

Executing operation SayHelloTo with parameters:

in0=小平

SayHelloToReturn=你好: 小平

Done!

.Net Client:
  先用如下命令生成代理类的程序 C# 代码:
  % Visual Studio .Net 2003 安装目录下的 %\SDK\v1.1\Bin\wsdl.exe
  具体命令行如下:
  wsdl.exe /l:CS /out:Class1ServiceProxy.cs http://localhost:1080/axis/services/Class1Service?wsdl
  然后用如下命令编译生成程序集: Class1ServiceProxy.dll
  csc /t:library Class1ServiceProxy.cs  然后用如下命令编译生成程序集: Class1ServiceClient.exe
  csc Class1ServiceClient.cs /r:Class1ServiceService.dll

using System;

using System.IO;

public class Class1

{

static void Main(string[] args)

{

//Download(ServerSidepath, ClientSidePath)

//Download(@"客户端本地路径", @"服务器端路径");

Download(@"d:\server\download\editplus.rar", @"e:\download_editplus.rar");

System.Console.WriteLine("down End");

System.Console.WriteLine("同步 up file exec

");

UploadFile(@"d:\Northwind.mdb");

System.Console.WriteLine("同步 up file End\n");

System.Console.WriteLine("异步 up chunks exec

");

UploadFileChunks(@"d:\editplus.rar", 64);

System.Console.ReadLine();

}

public static void UploadFile(string LocalFileName)

{

Class1Service xx = new Class1Service();

FileStream fs = new FileStream(LocalFileName, FileMode.Open); //Client Side Path

byte[] buffer = new byte[fs.Length];

fs.Read(buffer, 0, buffer.Length);

//调用 "同步执行" 的本地 Web Sevices 代理类的方法,相当于同步调用了 Web Method !

xx.UploadFileBytes(buffer, System.IO.Path.GetFileName(LocalFileName));

}

//指定要上传的本地文件的路径,及每次上传文件块的大小

public static void UploadFileChunks(string LocalFileName,int ChunkSize)

{

Class1Service xx = new Class1Service();

string filename = System.IO.Path.GetFileName(LocalFileName);

FileStream fs = new FileStream(LocalFileName, FileMode.Open); //Client Side Path

//fs = File.OpenRead(LocalFileName);

int r = (int) fs.Length; //用于记录剩余还未上传的字节数,初值是文件的大小

//调用 "同步执行" 的本地 Web Sevices 代理类的方法,相当于同步调用了 Web Method !

//预定服务器端空间

xx.CreateBlankFile(filename,r);

int size = ChunkSize * 1024;

int k = 0; //用于记录已经上传的字节数

i++; //用于记录上传的文件块数

while (r >= size)

{

byte[] buffer = new byte[size];

fs.Read(buffer,0,buffer.Length);

//调用 "异步执行" 的本地 Web Sevices 代理类的方法,相当于异步调用了 Web Method !

//该 buffer 的字节要写到服务器端相应文件的从 Position = k 开始的字节

xx.BeginUploadFileChunkBytes(buffer,k,filename,new AsyncCallback(UploadFileChunkCallback),xx);

k += size;

r -= size;

i++;

}

if (r > 0) //剩余的零头

{

byte[] buffer = new byte[r];

fs.Read(buffer,0,buffer.Length);

//调用 "异步执行" 的本地 Web Sevices 代理类的方法,相当于异步调用了 Web Method !

//该 buffer 的字节要写到服务器端相应文件的从 Position = k 开始的字节

xx.BeginUploadFileChunkBytes(buffer,k,filename,new AsyncCallback(UploadFileChunkCallback),xx);

i++;

}

fs.Close();

}

private static int i = -1; //用于记录上传的文件块数

private static void UploadFileChunkCallback(IAsyncResult ar)

{

Class1Service x = (Class1Service) ar.AsyncState;

Console.WriteLine(x.EndUploadFileChunkBytes(ar));

if ( --i == 0)

{

Console.WriteLine("异步 up all chunks end");

}

public static void Download(string ServerSideFileName,string LocalFileName)

{

Class1Service xx = new Class1Service();

byte[] b = xx.DownloadFileBytes(ServerSideFileName); //Server Side Path

FileStream fs = new FileStream(LocalFileName, FileMode.Create); //Client Side Path

fs.Write(b,0,b.Length);

fs.Close();

}

运行 Class1ServiceClient.exe 即可!

运行结束后请检查 D:\Server\Upload\ 目录中是否已有文件上传!
