Yes! Careful work with classloaders can do the job. This is possible, because Struts runtime control any use of Action classes, and, presumably, user do not use Action classes directly from users code. That might work for Actions, but how about for beans in general? Or classes loaded from a parent class loader (like classes from common/lib in Tomcat)? I'm really not interested in trying to support fancy class loading tricks like this, across all platforms, in the Struts codebase itself. It was hard enough to get class loading inside *one* container (I wrote a large chunk of the Catalina code in Tomcat) to work reliably. If you are interested in trying this with Exadel, then more power to you ... and I'll happily send the support questions to your user list instead :-). Best, Igor.

I use ant.

Subject: RE: Struts Action Scripting
True, but I think recompiling is the time consuming part!
Recompiling the actions or jsps? If it takes you more than 1
second to
compile an action, you're using the wrong tool. Eclipse performs
incremental compilation every time you save a .java file so
you don't even
notice that it's compiling. I've had people ask me how to
compile and build
projects in eclipse because they didn't realize it was all
automated for
them!
David
I've also done a small integration project using BeanShell scripting
(for
actions), if anyone is interested, I'll be willing to share it!

One of the stated benefits is that you don't have to
reload your app
to see changes in actions. I think the idea is neat but
would never
use it because
Tomcat reloads my app in 3 seconds.

Then you get back to a spageti application ... :)

Subject: Struts Action Scripting
Just found this at
http://www.alphaworks.ibm.com/tech/strutsscripting
From their Overview:
The ScriptedAction is a Struts Action class that uses BSF (Bean
Scripting
Framework) to enable Struts developers to create Struts
Actions in the
language of their choice. Supported languages include:
JavaScript, Jython,
Jacl, ActiveScript, PerlScript and others.
When specifying the type of an action, the ScriptedAction is
specified
and
the parameter attribute is used to tell the ScriptedAction
which script to
load and execute. The ScriptedAction uses BSF to setup the
script runtime
environment with declared variables for the arguments
typically passed to
the execute method of an action, as well as a context object
that provides
a way for the script to specify the forward for the action to
return.
Currently, there is some function for customizing the execution
environment of scripts to make the scripting of Actions
easier and
friendlier by allowing the definition of predefined
variables and
functions available to all scripts. Future plans include an
extension
mechanism to allow for the registration of new BSF
engines and file
extensions for different languages.
Cheers,
Gustavo

Re: Struts Action Scripting
Why reload all application in 3 seconds - my application tomcat reloading much longer and not evry time :-( - if I can reload just that action in 0.3 seconds bullet proof?
