Hi,

This forum is the best place to be if I have any doubts at all . Thanks for all the help till now .

I am working with Struts1.x and I seem to be having trouble in doing anything actually . I created this simple login page and form bean for that page . Then an action class to work on the page request .

Here is the code .

this is login.html

then here it the form bean LoginForm.java

package com.emr.forms;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;

public class LoginForm extends ActionForm 
{
	
	private String username;
	private String password;
	
	public ActionErrors validate(ActionMapping mapping,	HttpServletRequest request) 
	{
			ActionErrors errors = new ActionErrors();
			if(username==null || username.length()==0){
				System.out.println("Error !");
				//errors.add("username", new ActionError("error.userName.required"));
			}
		
			return errors;
			
		}
	public void reset(ActionMapping mapping, HttpServletRequest request)
	{
		password = "";
		username = "";
	}
	
	
	public LoginForm(){}
	
	public String getUsername() 
	{
		return username;
	}
	public void setUsername(String username) 
	{	
		System.out.println("---------- username is set in the form -----");
		this.username = username;
	}
	public String getPassword() 
	{
		return password;
	}
	public void setPassword(String password) 
	{
		System.out.println("------ password is set in the form ---------");
		this.password = password;
	}
	
	
}

then there is the web.xml ( which i think seems to be causing the problem )

<?xml version="1.0" encoding="UTF-8"?>

So what do you expect this code to do and how is it not doing that?

Hi ,

thanks for the reply . Since i am new to this Struts 1.x , I dont know how the mapping occurs but the basic flow that I want to follow is HTML -> Form Bean (Storing the HTML field data ) -> Action ( where the data from Form bean is taken) -> action forward -> result page .

And since the page is not doin anything I am wondering the problem maybe with the web.xml file .

Thanks and regards
Varun

Unless you have a good reason to learn Struts 1.x, like you are going to be maintaining an existing application, I recommend you learn Struts 2.x. Struts 1.x has some serious drawbacks that Struts 2.x addresses.
That said, you have to tell the form where to send the data. Look up the "action" attribute for the HTML form tag.

Hi ,

Thanks for the reply . Yes I do have to maintain an application which was implemented in Struts 1.x . And I did look up the "action" tag . But I could specify the action but that would lead the flow directly to the action whereas I need the data from the HTML form to stored in Form Bean first .

Thank you and Regards

That's what Struts does. It populates the bean, uses the bean to do validation (if the validate method is implemented), then passes it to the action.

Hi ,
