Difference b/w WWE and WDE

Hi,

I have few questions in Workspace Web Edition, can some please clarify those questions.

a) Can anyone give me the difference between Workspace Web Edition and Workspace Desktop Edition
Based on document i notice difference, WWE can access both Cassandra DB and Config DB (is there any other difference other than this)

b) WWE can deploy in Apache Tomcat Sever ?
c) WWE can customize through only Servlet or can we use JSP ?

Thanks,
Ram

Workspace Desktop Edition is a Desktop application (.NET, requires agents to install)
Workspace Web Edition is a web application (no client install)

WWE also depends on Web Services and also currently is not as functionally rich as WDE.
