I am trying the following but am seeing 'no ds injected'. Should this work at this stage?

*package* org.jboss.as.demos.warwithds.archive;

*import* java.io.IOException;
*import* java.io.Writer;
*import* java.sql.Connection;
*import* java.sql.ResultSet;

*import* javax.annotation.Resource;
*import* javax.naming.InitialContext;
*import* javax.servlet.ServletException;
*import* javax.servlet.annotation.WebServlet;
*import* javax.servlet.http.HttpServlet;
*import* javax.servlet.http.HttpServletRequest;
*import* javax.servlet.http.HttpServletResponse;
*import* javax.sql.DataSource;

*import* org.jboss.logging.Logger;

            }
