Application URL not working properly

Question

We have a custom application hosted on weblogic8.1 cluster. And this is in production environment.
What we observed was, I am using FireFox browser and works fine for me. And I noticed it did not work a few days ago only once. However, most of the other users use IE6.0 and seems not able to access this URL. So some tried using IE 7.0 and worked fine for some time. But, the problem persisted very often as few can and others cannot.
Can anybody tell me what could be the problem or should I be modifying any files in weblogic server.
This is working pretty fine in testing environement.

Answer 1

Thank you very much for the hint, though I have not tried your suggestion. I tried a little more and found the following way might be simpler - using "java.url.*" and "java.io.*". Just a simple test:
============================
URL url=new URL("ftp://usrname:password@hostname/localDirectory/filename.txt");
InputStream is=url.openStream();
BufferedReader in=new BufferedReader(new InputStreamReader(is));
String line;
while((line=in.readLine()) !=null) { System.out.println(line);
==========================================
Of course, other data format would work in a similar way.
