Re: [Springframework-developer] VelocityEngineFactory question

[<jue...@we...>]

Velocity.init and Velocity.getTemplate use their own singleton =
underneath - but you don't need to use that part of the Velocity API, as =
VelocityEngine is an alternative to it, AFAIK. The benefit of =
VelocityEngine is that you can have multiple Velocity configurations =
within the same application, i.e. within the same class loader.

If you use a VelocityEngineFactoryBean to set up a VelocityEngine =
singleton, that VelocityEngine instance will be a real singleton in the =
Spring application context. You need to invoke getTemplate on the =
VelocityEngine instance then instead of the static getTemplate method on =
the Velocity class. We're using this ourselves for email templates; it =
does work properly.

   It is singleton in terms of Spring bean configuration process
   but not a real singleton.

   A single call to Velocity.init(properties) is needed to initialize
   the engine as a singleton. Later in the code you simply use
   Velocity.getTemplate(templateName) to get the template.
