I use this with the following simple logic in a processing class called by my Action
class. You can do whatever you like to use the results of the !ButtonCommand class.
You don't, of course, have to have a Struts solution to use this.
+Assume that you have code like:
+
+{{{
+<input type='image' name='submit'>
+}}}
+
+Or:
+
+{{{
+<html:image property='submit'/>
+}}}
+
+or whatever else you may have going on. Actually I automatically generate and cache
buttons of the right size, color, background, etc. on the fly in 15 languages as
follows:
+
+{{{
+<crackwillow:image
+ button='HOSTS.gif'
+ mapBean='host_container'
+ bgClr='ffffff'
+ txtClrCode='banMddlBgClr'
+ font='Eurostile'
+ italic='false'
+ bold='true'
+ size='20'
+ property='hostsOptions'/>
+}}}
+
+The point is that the preceding solution is not tied to other decisions but merely to
utilizing what we need to get the job done with <input type='image>. We use the class
as follows.
+
{{{
if ("submit".equals(ButtonCommand.getCommand(request))) {
// do whatever
}
-}}}
+}}}
+
+This solution is very, very simple and very, very effective. I think it is the best
out there.
-Most importantly, there is very, very little overhead either in footprint or in
calculations with this solution. A vastly inferior, but more typical solution follows.

SOLUTION TWO: THE TYPICAL BUT INFERIOR SOLUTION TYPE.
