Hello, I was working with java persistence on glassfish 3 + eclipselink, and everything was good, but then I needed to make some Group By queries, so i decided to make this in JSP.

And here is an error: javax.servlet.jsp.JspException: Unable to get connection, DataSource invalid: "java.sql.SQLException: No suitable driver found for jdbc/zetowr_at_energia"

But the driver is in place, whatsmore, I can use it to use Java Persistance with the same JDBC resource. What might be the problem?
