Thanks for the reply, but did not work, here is outline of my class to handle custom protocols and I set the system property as -Djava.protocol.handler.pkgs=com.acme.protocol.handler.CustomProtocolUHandler Can you please suggest what could be wrong? Thanks again. package com.acme.protocol.handler; import java.net.*; //import java.util.*; import sun.misc.*; import com.rsa.ssl.*; import java.io.File; public class CustomProtocolHandler implements URLStreamHandlerFactory { public URLStreamHandler createURLStreamHandler(String protocol) { protocol = protocol.toLowerCase(); //We are also returning our handler for handling of dummy protocols like javascript: or about:blank if(protocol.startsWith("myhttp")) { return m_protocolHandler; } else { return null; } } public static void main(String[] args ) { System.out.println("main Method called"); try { CustomProtocolHandler customProtocolURLStreamHandler = new CustomProtocolHandler(); java.net.URL.setURLStreamHandlerFactory(customProtocolURLStreamHandler); } catch(Exception e) { System.err.println("Exception while setting the URLStreamHandlerFactory object"+e ); } } } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4113918#...
