html:form tag doesnt have a name attribute.
it automatically gives the type value as it name

<html:form action="name" type="STRUTS.NameForm">

Yes i know.
Figure it out before so now i have a text field i have to place name in.
after submit i debug and see that he got the currect name.

But now on Success i told the system to go to jsp page.
return mapping.findForward(target)

In the config file it says  <forward name="success" path="/welcomeStruts.jsp"/>

but after i submit i cant see this page, just blank one with STRUTS.do in the address.

Any idea why

>>"return mapping.findForward(target)"
should be
return mapping.findForward("success")

as your struts-config.xml defines <forward name="success" path="/welcomeStruts.jsp"/>

You can use request to help you to do that.

request.setAttribute("whateverIdentificationHere", "anyValue");
return mapping.findForward(target);

Then in your JSP, you can get it using
<%
    out.println(request.getAttribute("whateverIdentificationHere").toString());
%>

>>"and if i have to do some Database work should i do it in the NameAction file?"
Yes, every business logic should be done in Action.

>>"what is diff between nameAction.java and nameForm.java"
Well, Action is the place where you will put all your business logics and etc. Form will only play part as the medium to send and retrieve the parameters from / to JSP. So let say that you are submitting one textbox value, it will go to the Form and the values in the Form will be retrieved in Action.

Hope that helps

I assumed that you have userName variable in your LogInForm class. Do you create the setter and getter?

And I think that this question is worth to be splitted. Am I right?

I need to go soon and will be back in few hours time

Yes i did,

   private String UserName=null;
    private String UserPassword=null;
   
    private int number;
   
    /**
     * @return
     */
    public String getUserName() {
        return UserName;
    }
     public String getUserPassword() {
        return UserPassword;
    }
    /**
     * @param string
     */
    public void setUserName(String string) {
        this.UserName = string;
    }
     public void setUserPassword(String string) {
        this.UserPassword = string;
    }


Anything wrong with this>?
