Directory listing capability for Resource Loaders

["Gerald E. Bennett" <mr...@austin.rr.com>]

Hi everyone,

I am trying to figure out if Resource Loaders have the capability to list
all available templates
that area available to them ?

For example, a FilResourceLoader would give a list of all filenames for each
of the directories listed in the
resource.loader.path.

Similar a Classpath loader would list all template filename available in the
classpath.
It would also be nice if I could only list filenames with a particular
extension.


Sincerely,

Gerald E. Bennett

It's *possible* to do, but not probable that we would make it do that :) 

You could always write your own quickie tool that gets from the Velocity
engine the current file.resource.loader.path and checks it as you wish. 
The configuration information is easily accessable via the getProperty()
method in the Velocity class (in org.apache.velocity.app).  Note that it
returns an Object, which could be a String[].

That's harder.  As rafal said, see the docs on Classloader to see why
that's hard. :)

While the tradition if .vm, there is nothing that says a template has to
have any extension....

Please read the API for java.lang.ClassLoader, and answer your own
question...
