Multiple Velocity Engines?
Is there a way to initialize several velocity engines? i.e. multiple
singletons?

Probably he should make own singleton wrapper and
instantiate VelocityEngine per use. Don't have example
available atm, but creating own VelocityEngine
instance was just to give constructor Properties
instance and its done. This allows different
.properties settings for each engine instance.
public class MyVMEngines {
private static engine1, engine2;
public static synchronized VE getEngine1() {
...code here...
return engine1;
}
public static synchronized VE getEngine2() {
...code here...
return engine2;
}
}

I believe having multiple singletons would involve having multiple
class loaders. You may want to look in that direction if you really
need singletons.

multiple singletons is an oxymoron. :) you can only have one
org.apache.velocity.app.Velocity per classloader, and i would not
recommend classloader tricks to have more.
you should use org.apache.velocity.app.VelocityEngine instead. you
can have as many of those as you would like.
