i'm creating a web App of handle all sorts of things like booking, registering users etc.
currently i'm struck on vey first step that is users login!!
all the presantation part is done using jsp and struts tiles, whenever i rub the application welcome page is shown, after that there is a need to login inorder to book tickets. now this login form is in two part i.e. a page in which other one is inserted as segement and bean created with input from the segment here is the code for both these files:

<%@taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %>
<%@taglib prefix="html" uri="http://struts.apache.org/tags-html" %>
<html:errors header="error.header" footer="error.footer"/>
<html:form action="/login.do" method="POST" focus="username">
        <tr><td>Username:</td><td><html:text property="username"/></td></tr>
        <tr><td>Password:</td><td><html:password property="password"/></td>
        <tr><td><html:submit value="Login"/></td></tr>
and the calling jsp code named as "signin.jsp"
<%@taglib prefix="tiles" uri="http://struts.apache.org/tags-tiles" %>
<tiles:insert page="/WEB-INF/layout/layout.jsp">
    <tiles:put name="subtitle" value="Login"/>
    <tiles:put name="body" value="/WEB-INF/global/login.jsp"/>

and the loginbean(as named) code is

    private String username,password;
    public loginbean() {
        // TODO Auto-generated constructor stub
    public ActionErrors validate(ActionMapping mapping, HttpServletRequest request) {
        ActionErrors errors = new ActionErrors();
        System.out.println(" performing validation");
        if ((getUsername() == null || getUsername().length() < 1)&&(getPassword()==null || getPassword().length()<1) ){
            errors.add("name", new ActionMessage("error.username.required"));
            // TODO: add 'error.name.required' key to your resources
//login object creation
        Login user= new Login();
//loginDAO object to access the database
        loginDAO search = new loginDAO();
        user = search.getuser(user);//search method returns login object, methods searches for the list of registered users.
        System.out.println("user from database"+ user.getUsername());//never seen in server log file.
        if(!(getUsername().equals(user.getUsername())) || !(getPassword().equals(user.getPassword())))
            errors.add("invalid", new ActionMessage("error.false.required"));
        return errors;
    public String getUsername() {
        return username;
    public void setUsername(String username) {
        this.username = username;
    public String getPassword() {
        return password;
    public void setPassword(String password) {
        this.password = password;
when i try to access the signin.jsp it is shown well( as expected) and if textbox are left blank and request is made it returns error as expected but if i left even a single field blank then it returns a error

i think you also want to see config.xml in order to go through here it is (code shown is a part of it)
        <action input="/views/signin.jsp" validate="true" name="loginbean" path="/login" scope="request" type="controller.login">
        <forward name="error" path="/views/signin.jsp"/>
        <forward name="member" path=""/>
        <forward name="employee" path=""/>
        <forward name="admin" path=""/>
it is showing error but when the values are entered it return that error??
do ask if you think information provided is incomplete!
i'm totally confused what to do ?
thanks in advance.
