I'm trying to figure out what version of struts I am using by looking at the jar and can't seem to find any info in it. How can I determine what version I am using?

I am thinking it is 1.2.2, but can't be sure. It looks like 1.2.6 is the latest. Are there any considerations for upgrading to 1.2.6?

Thanks.

The only way I know to tell which version of struts is being used is to un-jar the struts.jar file and look at the modified dates on the included objects. By downloading the various versions and comparing the dates in the downloaded version with the one you have, you can determine what the version is. It would be nice if there were a readme.txt file or something that containted the version number, but there isn't.

As far as compatibility goes, I haven't run into any problems upgrading minor releases. Even if something is deprecated, the old way will usually still work.
