Re: [Actionframework-users] bug in VelocityInOutVariable for multiple servlets

When i said "multiple servlets" i should have said "multiple web applications".
The actionframework examples war puts all the servlets into a single web application.
That means there is just a single url mapping, and so the bug i mentioned
doesn't happen.

However, if you have multiple web apps, things go wrong.

In fact, the way that I found this problem was by trying to reorganize the 
actionframework examples in a way that will work treating each example as its own web
application with its own web.xml file.
Currently there are about 3 copies of all the examples, and still it doesn't
work out of the box with a standard J2EE container, so far as i can see.
In my rearranged version, i have an "examples-src/" directory that:
 - just has the sources
- is not run from
 - has webmacro syntax

Then there is a derived tree under build/webapps that:
- will generated vm for velocity or wm for webmacro according to what is asked 
- will optionally generate all the servletrunner cruft, but not unless asked
- will work out of the box with a J2EE standard servlet container

It looks like this:
   build/
      webapps/
          Calculator/
              WEB-INF/
                   web.xml
                   classes/
                       Calculator.class
                   vm/
                       Calculator.vm
                       error.vm
                   config/
                       Calculator.xml
                       Velocity.properties
           Calculators/
               ...

servlet containers such as jetty will run everything under a webapps/ directory
automatically.

although currently i'm running into various problems with actionframework, such as that
class static variable.
also, without my patch for getRealPath, it is awkward when an application uses
ActionServlet directly without subclassing (because WEB-INF/classes won't
be in its classpath because its instance doesn't have that for its classloader).
