Exception when accessing RMI methods from XSP

[Idhaya Chandran <id...@coreobjects.com>]

Hi,

I am trying to access a RMI Server from an XSP page.
I am looking up the remote object and invoke the method on that.
When I invoke the remote method, I am getting the following exception.

"java.net.MalformedURLException: unknown protocol: jndi"

Please help me to fix this.
Thanks in advance
