The above solution is ugly. Is there a more elegant solution (perhaps something has changed with Struts in the few years that the post was made...) ? Is it possible to use #request.requestURL, or something similar? I tried a few by trial and error and was unable to find a solution on the web.
If you use the <s:debug/> tag you can see what's in the value stack and see if anything's changed (I've been out of the loop for about a year). Another trivial option would be to just create an interceptor that puts it on the stack--that's all any new S2 code would do anyway. Or get it in the action.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
