Hello,
I think the only solution is to create the instance of the map in java.
Then put the instance into the velocity context.
Thats it.
As I faced the same problem, I have written my own java class to start velocity.
Then I have a property to instantiate HashMaps and ArrayList in this class
which will be added to the velocity context. After a template was processed,
the Maps and Lists are cleared by my java class.
(But you can also clear the Maps/Lists in the template before using them.)
Well, I dont know how this approach will work with the velocity resource
loaders. I use velocity to generate plsql code from templates and therefore I
read the template files by myself.
