Relation between Internet Explorer and Socket Connection

[Prakash Dwivedi]

Hello,
i am developing a servlet in which i have to read data from some other web application(at present this another web application is running on different machine, but on same LAN). To do that i establish httpUrlConnection. Following is the code

 
      URL externalURL = new URL("http://192.100.100.249:8888/blackbox/servlet/servlet2");
      HttpURLConnection connection = (HttpURLConnection)externalURL.openConnection(); // Opening the connection
      connection.setRequestMethod("POST"); //setting the request method to POST
      connection.setDoOutput(true); 
      connection.setDoInput(true);
      OutputStream output = connection.getOutputStream();

the code gives java.net.SocketException while opening the connection.
I got even further confused when i added 192.100.100.249 in the list of "do not use proxy server for following ip addres" in Internet Explorer and my servlet started working correctly.
what i am not able to understand is the relation between establishing Socket Connection from a servlet and IE. I am using window 2000.
can any body help me.

Are we talking about IE running on the machine the servlet runs on -- in other words, the servlet is running on Windows?

Yes, but using it for what? Are you talking about IE and the servlet running on the same physical machine, or are you talking about IE being used to access the servlet from a client machine? While I'm asking, what servlet container are you using?

I am running my web application through JDeveloper which is having embedded OC4J.
