Could not initialize class com.isomorphic.datasource.DataSourceManager

[DSingh]

I am doing a POC using SmartGWT.mobile and SmartGWT version /builds/SmartGWT/2.5p/PowerEdition/2013-02-27

Can you give some input on below error?

You need to use SmartGWT.mobile with 3.x or newer builds.

This particular server exception suggests missing, corrupt or duplicated server .jars in your classpath. However fixing that problem will still mean you need to move to 3.x.
