Hi Nathan,
As suggested by you I tried using WebappResourceLoader.
For the same I downloaded velocity-tools-2.0-beta1.jar and configured
the jar in my server classpath.
I am using velocity-1.6.1.jar and velocity-1.6.1-dep.jar for the
Velocity Engine.
Now when I start the server I get the following error message:
[12/31/08 11:11:11:518 IST] 744f744f ServletInstan E SRVE0100E: Did not
realize init() exception thrown by servlet velocity:
javax.servlet.ServletException: LinkageError while defining class:
org.apache.velocity.tools.view.WebappResourceLoader
Could not be defined due to:
(org/apache/velocity/tools/view/WebappResourceLoader) bad major version
at offset=6
This is often caused by having a class defined at multiple
locations within the classloader hierarchy. Other potential causes
include compiling against an older or newer version of the class
that has an incompatible method signature.
Dumping the current context classloader hierarchy:
==> indicates defining classloader
==>[0]
...
---Original exception---
java.lang.UnsupportedClassVersionError:
(org/apache/velocity/tools/view/WebappResourceLoader) bad major version
at offset=6
The server is starting even after this error. But I doubt if Velocity
will work because of this error.
Please let me know what could be the reason for this exception.

You need to use the WebappLoader from VelocityTools. The
FileResourceLoader is far too much trouble to get working in a web
application.
Be sure to read:
