Hi Expert,

I have tried to use the following SOAP request in java applet viewer. It works fine.

      String url = "";
      URL HttpURL = new URL(url);
      conn = (HttpURLConnection)HttpURL.openConnection();

      conn.setDefaultUseCaches (false);

conn.setRequestProperty("POST", "/WsNew/recordingservice.asmx HTTP/1.1");
conn.setRequestProperty("Host", "");
conn.setRequestProperty("Content-Type", "text/xml; charset=\"utf-8\"");
conn.setRequestProperty("SOAPAction", "http://tempuri.org/GetRecordingID");

But when I try to run it in IE, it show the following error message:
java.lang.ClassCastException: com/ms/net/wininet/http/HttpURLConnection
      at com/pls/util/HttpConnectionTestTT.main
      at com/pls/util/WsNew.GetRecordID
      at com/pls/base/CallCenterApp$1.run
      at java/lang/Thread.run

This is because MS uses its own Java VM and its own classes.
While you had expected java.net.HttpURLConnection, it returned you com/ms/net/wininet/http/HttpURLConnection

In the IE, goto Tools->Internet Options->Advanced and check the option to use Java VM.
This might help

Hi Expert,

But I use Java VM, it will show the exception as below:

java.security.AccessControlException: access denied (java.io.FilePermission c:\javalog read)
      at java.security.AccessControlContext.checkPermission(Unknown Source)
      at java.security.AccessController.checkPermission(Unknown Source)
      at java.lang.SecurityManager.checkPermission(Unknown Source)
      at java.lang.SecurityManager.checkRead(Unknown Source)
      at java.io.File.exists(Unknown Source)
      at sun.applet.AppletPanel.run(Unknown Source)
      at java.lang.Thread.run(Unknown Source)

Is this class is not work in latest java VM?

import java.io.*;

Applet programs are not allowed to access the client machine's File system, that is the cause of your error.
Probably u can try commenting that code and similar ones - accessing the file. It seems like you are using a normal Java standalone application in your applet.
