velocity

I have an application where in I am trying to create a velocity template repository which will help me centralise all my email templates and will allow me to create a communication hub. All templates will be called at runtime and populates with data via services.

My problem is that I need to provide users with optional and compulsory params list when they define the template inputs for the velocity template.

Is there a way to read the tokens/tags from the velocity template file and extract them??

Like I want a list of tokens $name.address.streetName to be available to me from .vm file.

I do not want to go for Regex .

I do not have to cache or reuse them , its just going to be a one time read and store the default,compulsory & optional params in the database.

I am following these patterns : http://kickjava.com/src/org/apache/velocity/test/view/TemplateNodeView.java.htm

How to use String as Velocity Template?

Please advice.

Hello, I want to move something a set distance. However in my system there is inertia/drag/negative accelaration. I'm using a formula like this for it: velocity = oldVelocity + ((velocity - oldVelocity * inertia) where inertia is a fractional value like 0.25 So to move the item a set distance… >>> More
