Sorry I'm unable to comment due to rep or I would of asked for more clarification on what errors/etc you are seeing. That being said I have tested with both Tomcat 7.0.27 and Tomcat 7.0.41 with java full version "1.6.0_51-b11-457" and was able to use @Resource.

Context.xml

ResourceTest.java

import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;

import javax.annotation.Resource;
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;

@WebServlet("/ResourceTest")
public class ResourceTest extends HttpServlet {
  private static final long serialVersionUID = 1L;
  @Resource(name="jdbc/Sample")
  private DataSource ds;


public ResourceTest() {
    // TODO Auto-generated constructor stub
}


protected void doGet(HttpServletRequest request,
        HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
    PrintWriter out = response.getWriter();
    out.println("");


    try {
        //Context initCtx = new InitialContext();
        //Context envCtx = (Context) initCtx.lookup("java:comp/env");
        //DataSource ds = (DataSource) envCtx.lookup("jdbc/Sample");
        Connection conn = ds.getConnection();
        Statement s = conn.createStatement();
        s.execute("Select * From \"NBUSER\".\"Friends\"");
        ResultSet rs = s.getResultSet();
        while (rs.next()) {
            out.println(rs.getString("NAME") + " is my friend.");
        }
        conn.close();
    } catch (Exception ex) {
        ex.printStackTrace();
    }

    out.println("");

}

/**

protected void doPost(HttpServletRequest request,
        HttpServletResponse response) throws ServletException, IOException {
