John, what kind of problems did you encounter? Cataloging them here
will likely elicit solutions, and this may help others in the future who
encounter the same problems.

Craig, I had XML editors to do that. I will try the Struts Console you

where "package-a.xml", "package-b.xml" and so on contain the form

application.
Craig, thank you for this info.
Craig, does this confirm with the dtd file?
Validation against the DTD requires two things:
* Using the DOCTYPE declaration (as shown above) in the outer
configuration file
* Setting the servlet init parameter "validating" to "true" in
/WEB-INF/web.xml
for the Struts ActionServlet
It doesn't matter whether you use XML entities or not.
Also, can you tell us the site link on Internet that uses
hundreds actions?
I'm afraid I don't have permission to do that. But let's think for a
moment about what the difference between a Struts app with two actions
and a Struts app with 2000 actions would be. There's certainly going
to be a longer startup time (lots more stuff to parse), and more
memory required for all the classes. But, at runtime while the app is
executing, the only difference this makes is how long it takes to look
up the particular Action definition in a HashMap keyed by action
paths. Even with 2000 entries, such a lookup is pretty fast (and CPU
time on the server tends not to be the bottleneck in most web
applications anyway).
It seems this approach the best in all the options we discussed.
In fact, when I develop an knowlege site with forums in java. I first
used struts, then I had some problems on configure file so I used
another MVC approach. If I know I could do this way, I may stick with
struts in this large project.
If you had struggles with editing a large configuration file, I would
also suggest using one of the many tools available that provides a GUI
front end for this purpose. For example, a standalone tool that is
quite popular for editing configuration files is Struts Console:
