Hi all,

I hope this is the right place to ask this question.

I'm started learning JSP / Java and need some advice regarding an

I created a tutorial project which makes use of the following:

- Maven (as local server)
- Struts 2
- Freemarker (template engine)
This is (a part) of my web.xml:







This is my struts.xml:

        <package name="tutorial" extends="struts-default">
                <action name="index" class="indexAction">
                        <result type="freemarker">/ftl/index.ftl</result>

                <action name="login*" method="{1}" class="loginAction">
                        <result name="input" type="redirect-action">index</result>
                        <result name="success" type="redirect-action">home</result>

                <action name="home">
                        <result type="freemarker">/ftl/home.ftl</result>


Login Action (tutorialSupport extends ActionSupport):

package tutorial.actions;

import tutorial.comon.tutorialSupport;
import tutorial.dao.UserDAO;
import tutorial.vo.UserVO;

import com.opensymphony.xwork2.conversion.annotations.Conversion;

public class loginAction extends tutorialSupport {

        private String login = null;
        private String password = null;

    public String execute() throws Exception {
        String result = INPUT;

        UserDAO userDAO = new UserDAO();

        UserVO userVO = userDAO.getUserByLogin(login, password);

        if( userVO != null) {
                result = SUCCESS;

        return result;

        public String getLogin() {
                return login;

        public void setLogin(String login) {
                this.login = login;

        public String getPassword() {
                return password;

        public void setPassword(String password) {
                this.password = password;



index.ftl (FreeMarker template file):


<@s.form action="" method="post">
        <@s.textfield label="Login" name="login" />
        <@s.password label="Password" name="password" />
        <@s.submit />





import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import tutorial.dao.UserDAO;
import tutorial.vo.UserVO;

public class LoginService extends HttpServlet {

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

                UserDAO userDAO = new UserDAO();

                UserVO userVO =
userDAO.getUserByLogin( request.getParameter("login") ,
                                                request.getParameter("password") );
                if( userVO == null ) {
                        request.setAttribute("error", "login");

                else {
                        HttpSession httpSession = request.getSession(true);
                        httpSession.setAttribute("userVO", userVO);





When I submit the form, LoginService is called, lets assume my login
was incorrect, as soon as it gets to this line:


I get the following error:

#Start of the Error:




#End of the Error

If I would replace request.getRequestDispatcher("/
login.action").forward(request, response); with
request.getRequestDispatcher("/login.jsp").forward(request, response);
or something, then it will find the page but I'm not using the Action
class anymore then.

I hope I made my problem clear, my questions are:

1. Why can't I forward to any action?
2. Is this the logical way of handling forms, actions etc.
3. Any other suggestions or remarks?

Thanks and regards,


response); can only forward to .jsp files.
