First, I'll point you to the Struts 2 documentation wiki: most of what you ask here is covered--spend some time with it, the payoff is huge.

What do you mean you're "getting NumberFormatException at &varB"? Without any contextual information about under the exact circumstances you get the error it's essentially impossible to help. Is it on page render? Action execution? In the Struts 2 code or in your code? I don't know--so I can't help. This is a valid URL and shouldn't cause any problems. > 2.

In the sample above you're creating the URL outside of the <s:a...> tag and giving the URL an ID. Using that value in a plain HTML anchor tag is as simple as using the <s:property...> tag: <a href="<s:property value="#myUrl"/>">delete</a> > 3. One action is overriding another action.

Again, this statement doesn't make any sense out of context. Without the configuration of the current and target action and (at *least*) the JSP code you're using to generate the link it's completely impossible to guess what might be happening.
