我现在在写服务端，但是客户端是别的公司再写，我也不知道它是用C写的还是JAVA写的都有可能，
我怎么读取客户端的数据呢，不管是C还是JAVA
我用dateInputStream.readUTF();好像不行，值都没有。
因为这个项目的客户端可以用手机发送请求也可以用PC机发送请求，所以我该用什么来读取数据呢！！
希望有给点代码的！！谢谢了兄弟姐妹

这是我的servlet的code
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
DataOutputStream oStream = null;
DataInputStream iStream = null;
System.out.println(request.getInputStream().read());
try{

oStream = new DataOutputStream(response.getOutputStream());
iStream = new DataInputStream(request.getInputStream());
System.out.println("iStream:"+iStream);
System.out.println("oStream:"+oStream);
new RequestHandler(iStream,oStream);

response.setContentLength(oStream.size());
oStream.flush();
oStream.close();

} catch (IOException ie) {
ie.printStackTrace();
} catch (Exception e){
e.printStackTrace();
}

}
这是我的requestHandler
public class RequestHandler {
/**
*
* @param iStream
* @param oStream
*/
public RequestHandler(DataInputStream iStream, DataOutputStream oStream) {
try{
System.out.println("iStream:"+iStream);
System.out.println("到RequestHandler!");
//System.out.println("iStream.readUTF():"+iStream.readUTF());
Integer clientVersion = iStream.read();
System.out.println("执行到这了嘛！");
System.out.println("clientVersion:"+clientVersion);
int clientCommand = iStream.read();
System.out.println("clientCommand:"+clientCommand);
realDoCommand(clientCommand, clientVersion,iStream, oStream);
oStream.flush();
oStream.close();
}catch(Exception e){
e.printStackTrace();
}
}

/**
* 真正处理命令方法
* @param clientCommand
* @param clientVersion
* @param dis
* @param dos
*/

@SuppressWarnings("unchecked")
private void realDoCommand(int clientCommand, Integer clientVersion,
DataInputStream dis, DataOutputStream dos) {
// TODO Auto-generated method stub
String className = "";

try{
className = (String)CMDGlobal.handlerMap.get(clientCommand);
Class handle = Class.forName(className);
if(handle != null){

IRequestHandler requestHandler = (IRequestHandler)handle.newInstance();

requestHandler.doCommand(clientVersion,dis, dos);

}

}catch (InstantiationException e)
{
System.out.println("");
}
catch (IllegalAccessException e)
{
System.out.println("");
}
catch (ClassNotFoundException e)
{
System.out.println("没有找到实现类!");
}
catch (Exception e)
{
System.out.println("");
}
}
