Answer 1

You can’t nest JSP tags like that.

<s:hidden name="categoryId"  id="categoryId" value="%{name}"/>

This, however, makes no sense–if it’s not a form, why would you put the categoryId into a hidden form field? You’re not submitting a form, you’re clicking a link.

Put the categoryId into the URL as a parameter.

<s:url id="category" action="/editProduct.action">
    <s:param name="categoryId" value="%{name}"/>
</s:url>

Note that unless “name” is actually something very ID-like, it’s probably a bad idea to use it as a primary key.

You may want to go over some HTML and web app basics before proceeding too much further; it will save you time in the long run.
