Re: [OS-webwork] Adding Velocity Tools support

[Dag Liodden]

It would be great to be able to do this without subclassing the VM and 
instead just using interceptors. People might argue that this is wrong 
because it introduces the possibility to introduce view-specific 
behaviours into the controller (we are, after all, trying to introduce 
the VELOCITY Toolbox, even if it's not really view specific), but I 
don't think this is so bad. If this is an issue, perhaps it should be 
possible to actually apply interceptors directly in the result type 
definitions?

This goes back to a JIRA issue I filed about the VelocityManager and the
velocity servlet. Before, in ww1, you could subclass the velocity servlet
and add things you wanted to the velocity context. Now, you can't, because
of the way the VelocityManager is set up. It would be (still!) great if it
were refactored in such a way as to make it easy for people to swap in their
own extension, adding items to the context as needed. I can take a look at
this, if need be.

1. Add a generic ToolBoxInterceptor to parse the toolbox.xml-file from 
Velocity Tools 2.
Just use the bean tag in a VelociMacro
  

     

My solution:

1. Generic Filter implementation. Then the tools do not only work with 
Velocity, but also with every other templating technology. Oh, I forget 
that you are using ValueStack instead of page, request, session and 
servlet context attributes, and that propably needs a separate 
implementation.



   

Yup, I want to call e.g $datetool.format($blah) directly in Velocity. Still,
I don't know how to put things in this context without adding it to an
action superclass or in the VelocityManager. It should preferrably be done
from an interceptor... Jason?
