Hi mati_varini,

Try placing a copy of your SQLServer db driver in your WEB-INF/lib folder.

There seems to be a problem with the MyEclipse Tomcat sandbox server not finding the established db connection.

There is probably a better solution, but this worked for me.

When you get to the point of deploying to production you will probably want to remove this copy of the db driver, if your production tomcat has it already installed.

Regards,

-Glen
