FileResourceLoader and resource loaders generally: getting the context of a request

["Townson, Chris" <C....@nature.com>]

Hi all,

I'm just trying to work out if this is possible and how it would be done:

The problem:
------------
Currently, we're using FileResourceLoader to retrieve templates from the filesystem in the normal. I'm in the process of putting together a slightly customized version of this to resolve ambiguous requests (e.g. if templateName == null or length == 0, use look for a welcome file as configured in web.xml) ... we need to do this because the way we're running velocity is through a servlet which takes the template path as a request attribute, parameter or path info.

However, this means that it becomes impossible to #include or #parse a file without referencing it using the full path (i.e. #parse("anotherFileInThisFolder.vm") fails)

What I would like to do is, if we get a request like this, to add a test which discovers the path from _where_ the call was made and then normalizes it based on that information.

Possible?


Thanks in advance,

Chris

p.s. congratulations on going TLP! :D

Velocity 1.5 supports relative resource loading with #include and
#parse.

The 1.5 release is not ready yet but should be quite stable. You can
grab it from subversion.

To enable relative resource loading, put the following line in your
velocity.properties file:

eventhandler.include.class =
org.apache.velocity.app.event.implement.IncludeRelativePath
