There is no standard library with such controls in Java (as there is no
standard db-aware controls in C++). Delphi is shipped with components
invented by Borland. Similar components from Borland are also shipped with
JBuilder (I think you have to buy at least Professional version).

Try JBuilder and ask in Borland newsgroups. Personally I have never used
them, but having some experience with Delphi, these components seem quite
similar to Delphi ones.

Without additional programming - no. Better use JBuilder or find some other
set of components.

You can check demos from the JBuilder. JayBird is functionally more complete
compared to the InterClient. So any demo from Borland for InterBase should
also work with Firebird/JayBird. Though I'm afraid that most examples are
designed for JDataStore which was designed with the JDBC access in mind and
most of the JDBC things are implemented there. Unfortunately this is not the
case with Firebird and we cannot fully translate the JDBC specification to
the Firebird API calls.
