There is no reason why Struts can't figure out the URL and give it back. I
have not seen the JSON result used the way you have it configured.
Typically, you see the JSON result with a root parameter. The root is the
action property you want to be the root of your JSON object graph.
So what I would do is create an action member called targetUrl and create a
getter getTargetUrl(). Then I would set the value of this member to
whatever, targetUrl = "/pages/selectBook.jsp". If the username is a match
then you return SUCCESS. You don't even have to set the root since it will
return the action as the root by default. In your data you just look for
data.targetUrl and you should see what you need.
There are other patterns: you could use another property for errorMessages
when the login is no good, or use the same string. You can use a
collection, etc.
