websphere服务器中的servlet获取servlet执行结果异常

Question

//发送一个请求，并发送一个对象过去,获得一个返回的对象
public Object sendRequest(URL url, Object object) {
Object o = null;
try {
URLConnection con = url.openConnection();
System.out.println("111111111111111111111 " + url);
con.setUseCaches(false);
con.setDoInput(true);
con.setDoOutput(true);
con.setRequestProperty("Content-Type",
"application/x-java-serialized-object"); ObjectOutputStream out = new ObjectOutputStream(con
.getOutputStream());
System.out.println("22222222222222222222 " + url);
out.writeObject(object);
out.flush();
out.close(); InputStream in = con.getInputStream();
System.out.println("33333333333333333333 " + in.toString());
ObjectInputStream objStream;
objStream = new ObjectInputStream(in);
o = objStream.readObject();
System.out.println("44444444444444444444 " + url);
} catch (Exception e) {
System.out.println("sendRequest(URL url,Object object) --------------------error !");
System.err.println(e.toString());
}
return o;
}
在o = objStream.readObject();抛出IE异常。
说明，改程序在weblogic服务器中执行正常。

Answer 1

更正一下
在o = objStream.readObject();抛出IO异常。 

Answer 2

java.io.IOException: Server returned HTTP response code: 505 for URL: http://192.168.1.200:9080/servlet/BusModuleServlet?Action=searchList&Where=C_Module_ID like '{C{'

这个异常是因为http地址传输的过程中有空格，替换掉后同样的捕获，打出的异常为java.io.EOFException
没有其他的信息。

Answer 3

Server returned HTTP response code: 505 for URL505 - HTTP 版本不受支持，我猜测可能是下面的某个属性没有被支持con.setUseCaches(false); 
con.setDoInput(true); 
con.setDoOutput(true); 
con.setRequestProperty("Content-Type", 
"application/x-java-serialized-object");尤其是红色部分不知道是什么属性，没有见过
