contrib/scripting/velocity is missing suitable resourceloader for the JCR
-------------------------------------------------------------------------
Key: SLING-1708
URL: https://issues.apache.org/jira/browse/SLING-1708
Project: Sling
Issue Type: Bug
Components: Scripting
Environment: Felix 1.4, Sling 2.0.7, Apache Velocity 1.6.2
Reporter: Olaf Otto
Affects: Rev. 989119 of
https://svn.apache.org/repos/asf/sling/trunk/contrib/scripting/velocity
(2.0.0-SNAPSHOT)
The velocity resource manager
(org.apache.velocity.runtime.resource.ResourceManagerImpl) has, by default,
only an org.apache.velocity.runtime.resource.loader.FileResourceLoader
instance. This resourceloader cannot load resources JCR resources as it
attempts to access the filesystem.
To reproduce, simply create a .vlt script and add an include directive:
template1.vlt:
#include("/path/to/template2.vlt")
This will fail:
org.apache.velocity.exception.ResourceNotFoundException: Unable to find
resource '/path/to/template2.vlt'

org.apache.velocity.runtime.resource.ResourceManagerImpl.loadResource(ResourceManagerImpl.java:483)

A suitable resource loader should be provided to the VelocityEngine instance
(perhaps in the VelocityTemplatesScriptEngine).
