Problem wtih JDBC Connecting in jsf program.

Question

Hey guys. I have a web app setup thanks to some of you guys on here. I'm using mysql jdbc access for login. I'm using the connection pool and resource for connectivity.
Basically what I'm asking is can I use to DataSource variables on the same page. The reason I'm asking that is. I can connect fine with the login code.

public class Login {
    @Resource(name = "jdbc/must2")

    private String email;
    private String password;
     * @return the email
    public String getEmail() {
        return email;
     * @param email the email to set

        this.email = email;

    public void setPassword(String password) {
        this.password = password;
    public String VerifyUser() throws SQLException {
        if (this.email.equals("") || this.password.equals("")) {
            return "fail";
        } else {
            if (ds == null) {
                throw new SQLException("No data source");
            Connection conn = ds.getConnection();
            if (conn == null) {
                throw new SQLException("No connection");
            try {
                PreparedStatement passwordQuery = conn.prepareStatement("SELECT password from user WHERE email = ?");
                passwordQuery.setString(1, this.email);
                ResultSet result = passwordQuery.executeQuery();
                result.next();
                String storedPassword = result.getString("password");
                System.out.println(storedPassword);
                if (this.password.equals(storedPassword)) {
                    FacesContext context = FacesContext.getCurrentInstance();
                    HttpServletRequest request = (HttpServletRequest) context.getExternalContext().getRequest();
                    HttpSession httpSession = request.getSession();
                    httpSession.setAttribute("login", "Login");
                    System.out.println("Success");
                    return "success";
                } else {
                    return "fail";
            } finally {
                conn.close();
                System.out.println("Login connection closed");
}Ok now I have some separate code that access the same database but fills a table on the same login.jspx page.
package page;
import java.util.ArrayList;
import classes.Line;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.annotation.Resource;
import javax.sql.DataSource;
public class LineStatus {
    @Resource(name = "jdbc/must2")
    private DataSource ds;
    private ArrayList line = new ArrayList();
    public LineStatus() {
        try {
            GetLineStatus();
        } catch (SQLException ex) {
            Logger.getLogger(LineStatus.class.getName()).log(Level.SEVERE, null, ex);
    public void GetLineStatus() throws SQLException {
        if (ds == null) {
            throw new SQLException("No data source");
        Connection conn = ds.getConnection();
        if (conn == null) {
            throw new SQLException("No connection");
        try {
            PreparedStatement passwordQuery = conn.prepareStatement("SELECT DISTINCT pkg_line_id,shortname, " +
                    "line_status FROM pkg_line_tree LEFT JOIN pkg_line using (pkg_line_id) " +
                    "WHERE tree_id = ? ORDER by shortname");
            passwordQuery.setInt(1, 3075);
            System.out.println(passwordQuery);
            ResultSet result = passwordQuery.executeQuery();
            while (result.next()) {
                line.add(new Line(58285, "Line 1", "Test", 43500, 21695));
        } finally {
            conn.close();
    public ArrayList getLine() {
        return line;
}There is nothing wrong with the code. I checked it over and over. Even replaced this code with my same login code that works. Every time I run the page I get "no data source". Obviously becasue Datasource is null. I have setup to catch the error. I'm guessing that the two backing beans can't access the same data base on the same page. I'm not sure though. I need to figure out how to get around this. Thanks for any help guys.
