Velocity Templating question

Hello,

Im trying to get to know the velocity templating engine.  Ive installed velocity, and i have working examples.  However, im trying to configure my VelocityServlet (child of..) to use templates from my template directory, but its not doing this.. i have the relative path to my properties file in my web.xml , and my properties file in turn has the entry :

file.resource.loader.path = /template

The templates, (weirdly) are being found.. but not where i expect them to be - they are in a completely seperate web application.  Its almost as though there is a general properties file over-riding the new one which i secify in loadConfiguration ();

The path to the props file is being read from the web.xml ok, and the path to the template directory is also reported in loadConfiguration as being correct..

any help appreciated..

I'd recomend using the class loader to access your properties files instead of specifying location on disk.
Either by using ResourceBundle, ClassLoader.getSystemResourceAsStream, or Class.getResourceAsStream.

Ok Objects,

Thanks for the suggestion, here is what i have now in my loadConfig.  I have put velocity.properties in my classpath, and it is being picked up fine.. still no joy though.  Still the templates are not being read from where i want them to be read.

Thanks,

Mehdi

       System.out.print("WE ARE USING : " + p.getProperty(Velocity.FILE_RESOURCE_LOADER_PATH));
       return p;

.. needless to say of course that the following line is in my velocity.properties :

file.resource.loader.path=D:\\webcontainer\\mehdi_cms\\templates

velocity.properties is in :

d:\classes\velocity.properties

contains :
file.resource.loader.path=D:\\webcontainer\\mehdi_cms\\templates

and my webapp is in

D:\webcontainer\mehdi_cms

Cheers,

Mehdi
