soap ui eclipse plugin - no packages are exported.

When i try to implement a class with the interface "com.eviware.soapui.eclipse.ISoapUIExtra" the class doenst compile. And then i found that the packages which we exported in 2.5 version are not being exported in 3.0. Is this an issue ?

I need to extend the soapui eclipse plugin fuctionality to add a few actions on the nodes in the navigator view of soap-ui plugin. how can i do this now, if this interface is not being exported anymore ?

Please help me if i am missing any new feature in the latest soap-ui eclipse plugin.

thanks,
Harsha.
