JSP and ValueBean..Tight Coupling..

[Manohar Karamballi]

Hai All!
Here is my question.. I have one value bean and correspoding JSP page(Form) using ValueBean. Is there anyway that Valuebeans set Methods are automatically invoked when user submitted the form?
Or anyother alternative to accomplish this..
any Suggestions are appreciated
TIA

You need to study the JSP API documents, downloadable from SUN. There really is no shortcut to mastering JSP.
The <jsp:setProperty tag will automatically look for and call setX methods corresponding to FORM properties named X
You must be careful that the variable and setX method names follow the naming rules.

Hai William!
Thanks for ur reply.. But i tried it and it is not just working..
Here are two JSP pages.
JSP1: Here user will enter values,,,,,
<jsp:useBean id="login" scope="session" class="ValueBeans.Login" />
<jsp:setProperty name="login" property="*" />

<form action="display.jsp" method="get">
<Input type="text" name="UserID" >
<Input type="text" name="Password" >
<Input type="hidden" name="hidden" value="Set">
<Input type="submit" value="Login">
</form>
JSP2: Here i am trying to Display UserID but is not getting displayed.
<%@ page import="ValueBeans.*" %>
<jsp:useBean id="login" scope="session" class="ValueBeans.Login" />
<%
out.println("Hello world!");
out.println(login.getUserID());
%>
ValueBean: This is value bean
package ValueBeans;
public class Login
{
private String strUserId;
private String strPassword;
public void setUserID(String strUserId)
{
this.strUserId=strUserId;
}
public void setPassword(String strPassword)
{
this.strPassword=strPassword;
}
public String getPassword()
{
return strPassword;
}
public String getUserID()
{
return strUserId;
}
}

So..Pls tell me where i am going wrong?

You are not following convention:
Try:
<Input type="text" name="userID" >
<Input type="text" name="password" >
I.e., lower case beginning letter of input element name.

You need to move the setProperty code to display.jsp.
