DataGrid widget usability

Hello, I am trying to use the DataGrid widget for the practical purpose of displaying a Teradata table.
For that i need to change the column definition among other things.
I started with the working widgetopia portlet and i added one more column .  I made the following modifications
 
(1) added getter / setter / field in WidgetopiaDataGridModel
(2) modified messages.properties ( still not clear how this file is invoked/used)
(3) modified WidgetopiaColumnDefinition
(4) modified WidgetopiaPreferences
I am not very excited of having to modify the table columns in so many different plances, i would much rather use the jdbc metadata to reflect the table columns, but regardless i was trying to get something working.
Right now, when deploying, i get the following warning on tomcat console , and the portlet no longer shows as avaialble to use . Please advise on how to troubleshoot , because the tomcat message is not giving me enough clues of what went wrong . Is there a way to enable logging or a more verbose logging for the portal rather than use the tomcat console ?

Look at the Dynamic Query portlet in the PDK.  It lets you run an ad-hoc SQL statement against Teradata and generates a data grid based on the JDBC ResultSet metadata.
