Any way to internationalize BIRT reports without property files

BIRT supports l10n an i18n using simple property files. I'm running reports from Jboss and my rptdesign files are stored in database.开发者_开发百科 When creating design I'm providing InputStream

design = engine.openReportDesign(designStream);

I think there is no way to do the same with localization property files. This separation is quite inconvenient. I'm wondering if there is any way to handle localization without property files? For example from database. Or it would be great to store localization map in .rptdesign file.
