Struts <html:img> question

I posted this topic in the New to Java forum but thought I would have more luck here.

I'm using struts and would like to get the name of an image file from a session attribute i.e. -

ActionClass

session.setAttribute("image", imageName);

JSP

<html:img src="../images/<%=(String) someAttributeImageName%>.gif"><html:img>

My questions are:

1. If I declare the session attribute in the action class, how do I access it in the html:img src attribute?

2. What other html:img tag attributes do I need to use?

3. Is there a better way to do this?

Thanks for the help, I'm still rather new at this technology and have a lot to learn!

In the Action Class u set the attribute imageName right!

First way

every JSP page has a request object. And so do this in ur jsp

<%

HttpSession session = request.getSession();

String imgSrc = "../images/"+(String)session.getAttribute("imageName ");

%>

<html:img src="<%= imgSrc %>"/>

Second way -

If u have a formBean or in fact any bean that holds the info about this form then u could easily set the attribute imageName on that form. Since the form is always in the request, when u return to a jsp, u can refer to the imageName through that form's accessor method. U do not have to get the handle to a HttpSession in this case. Ofcourse all of this will be possible with struts..
