Subject Re: I am abel to ping the machine but still received exception "Could not connect to broker URL"
Date Mon, 23 Jun 2008 18:03:37 GMT

hey Thanks Sridhar2008.

I don't know what is the reason. But here is what I did :
Installed broker on UNIX and started it there. Then I sent few messages from
windows machine to unix bix and that worked.
" I guess this issue was related to firewall - windows machine is not
accessible from unix, but unix machine is accessible from windows machine. "

Thanks,
