Re: [Fwd: Re: [RMI] Questions about RMI and Tomcat/Apache]

David,

you may be interested to take a look at the Bantam project (
bantam.dev.java.net).  Bantam remote services deploy as WAR files, and
client/service communication happens entirely over the HTTP port.

You can try it out using our live demo site (
http://bantam.skillcorp.com/bantam-examples/)  and the sample client that's
part of the project download.

HTH,

-Tom
