Ekit Java - can anyone help with class files?

[Princessbride]

I've just installed a PHP based CRM app. and everything looks and runs fine except the mail module. This is called Webmail2 (that's all I know about it). Receiving mail is fine but the compose window is Java based. The java it's looking for is called Ekit - it didn't install with the app and so returns an error when called. I've posted on the developers site but their response is very slow. I found Ekit online and can run it locally but I don't have the class files required for the server. Is anyone familiar with this? If so how do I get the class files and how do you install it?

Thank you is advance.

Found the problem. The Ekit.jar file supplied in the bundle was corrupt. Installing a new copy from the Ekit developers site fixed it.
