Report Internationalization

Hi,
Is there any way to do Internationalization in BIRT without using properties file?

I mean we have all our messages in DB with key-value pair instead of properties file. Using Resource Bundle we are retrieving the value based on the key we are passing using web service from the cache.

How do I access this value in the report for each and every labels I need to use in the report?

Cheers,
Priya
