Hi
Can you provide more info on "payment gateway" and how do you connect to it. Is it an ejb that you are invoking or is it a HTTP URL connection that is being created

hi rahul,
thanks for the help....
previously i was trying it with a simple session bean using weblogic 8.1. Then i made a simple jsp and put that in an ear and tried that on weblogic. For this simple JSP also, its giving the same error. The payment gateway that i'm connecting is datacash and the url for that is "https://testserver.datacash.com/Transaction".I also tried a simple public static void main example from my command prompt which worked completely fine. Then on similar lines i made a JSP which failed completely. The code of jsp is giving below:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<%@ page import="com.datacash.util.XMLDocument,
java.util.Hashtable,
com.datacash.util.CardInfo,
com.datacash.errors.FailureReport,

com.datacash.logging.Logger,
com.datacash.logging.LogListener,

I suggest checking out Jakarta Commons HttpClient. It has excellent support for things like https and web proxies.

The solution provided by Chris is good. Try reusing Apache classes if you can.
