Is it possible when using a select box to display form elements depending on which option was selected for example:
<select>
<option value="d1">Option One</option>
<option value="d2">Option Two</option>
</select>
If I selected "Option One" a textbox and a submit button would appear. For "Option Two" a radio button and a textbox plus a submit button would appear.
If I use a servlet and JSTL and spring how could I get this to work? I'm new to Java so a detailed description or a tutorial would be great. I have javascript to make it work but having a problem when submitted the form elements disappear and I have to select option 1 or two again.

You don't need struts, struts can't solve this problem as well.
Since you have the javascript to render the textbox and button when selecting the select box, what you need is to execute the javascript during page load (<body onload="..">) and pass in the value of the select box from request parameter/attribute, if the value from request is empty then dont do anything in the javascript.

Or I can use Struts if that would be better. Even though I don't know Struts well either.
