While integrating Jboss with eclipse, in eclipse, software updates and install, i took the plugin from URL
http://download.jboss.org/jbosside/updates/stable.
But its not able to copy
SeamTools Feature (2.0.0.GA) requires feature "org.eclipse.datatools.connectivity.feature".

I unchecked above and finished the download. Plugins have come in eclipse but in Jboss Server View, following exception is coming:
