JSP 2.0 JSTL

[Kevin P Smith]

Hi

Just wandering if anyone could help me out with a quick fix.

I'm looking for a quick simple example of JSP2.0 with JSTL or EL to connect to a Bean.

I have seen examples of how you retrieve data from a Bean but I was wondering if someone could throw in a quick example of populating a Bean, say for a registration page
of a site or something.

Something simple like this:-

import java.io.Serializable;

public class RegUserBean implements Serializable {

	public String name = null;
	
	public RegUserBean() {	
	}	
	
	public void setName(String name) {
		this.name = name;
	}
	public String getName() {
		return this.name ;
	}
}

JSP

<form action="register" method="POST">
   <input type="text" value="" name="name" />
   <input type="submit" value="submit name" />
</form>

I assume that you mean after submitting a form? If so, then this is something that should be done in a servlet rather than a JSP. You could use <c:set> for this in a JSP, but submitting form data directly to a JSP would be considered a poor practice.

You can use the (legacy) jsp:useBean for that. But I agree with Bear that it should be done at in a servlet. That's the right approach nowadays. There are utilities and frameworks available which can populate beans for you 'automagically', for example Apache Commons Beanutils. If you want to do it at a bit higher level, consider JSF or Struts. In both MVC frameworks you've only 'action beans' and there is no need to write a servlet yourself.

So basically the only was is to use the old

SomeServlet
SomeBean bean = new SomeBean();
bean.setName = request.getParameter("name");

There's no way of accessing a Bean directly from the JSP and setting the property?

OK, just wondered if JSP/Servlet had a way of accessing Beans directly (JSF style)

JSP/Servlet is just a basic API. JSF API extends JSP/Servlet with seamless bean-mapping like that.
