You don't really need to upgrade to 1.2.6, all you need to do is take the DownloadAction class (and the ResourceStreamInfo class IIRC) from 1.2.6 and use it. There's nothing that I recall that would make it not work in previos versions of Struts.
I have an app that downloads images from a database, and while I wrote a separate servlet to do it because of some security setup I had to provide for, the code is extremely similar to the DownloadAction... what your trying to do is in no way unusual, and anyone that has done it will have similar-looking code :) -- Frank W.
