Questions related to BIRT 2.2

[Dhaval]

Hi All,
I am evaluating BIRT 2.2 for our project, and was stuck up with the following issues:

1) How does BIRT support internationalization for dynamic data coming for the database?
2) Can we use simply Java instead of JavaScript in the functions?
3) Is it possible to map a date in the database (the date is store in long form in the table) to a normal date time form in BIRT without using JavaScript or java functions?
