RegisterForm.java:
package app;
import org.apache.struts.action.*;
public class RegisterForm extends ActionForm{
protected
String username;
protected String password1;
protected String password2;
public String getUsername () {return username;}
public String getPassword1() {return password1;}
public String getPassword2() {return password2;}
public void SetUsername (String username)
{this.username = username;}
public void SetPassword1(String password)
{this.password1 = password;} public void SetPassword2(String password)
{this.password2 = password;} };
RegisterAction.jsp:
package app;
import org.Apache.struts.action.*;
import javax.servlet.http.*;
import java.io.*;
public class RegisterAction extends Action
{
public ActionForward service (ActionMapping
mapping,ActionForm form, HttpServletRequest req,
HttpServletResponse res)
{
RegisterForm rf =(RegisterForm) form;
String username = rf.getUsername();
String password1 = rf.getPassword1();
String password2 = rf.getPassword2();
if(password1.equals(password2))
{
return mapping.findForward("success");
} else
{ return mapping.findForward("failure");
}
}
}
