[Zope] How to refer an object in a sub folder?

How to refer an object in a sub folder? I have a folder 'java' under a folder 'tech'. I have a template 'index' in 'tech'. How do I refer to 'index' in the folder 'java' from an object in 'tech'? <dtml-var java/index> ??? Thanks in advance, Samy Rengasamy.
