I cannot get any version of this Driver to work with Jasper Reports
however some minor changes to driver 1.5.6 and all seems to be working
well.

Edit the following two files
src/main/org/firebirdsql/jdbc/FBResultSetMetaData.java
Line 674 change as CHARACTER_LENGTH to as CHAR_LEN
Line 830 change CHARACTER_LENGTH to CHAR_LEN


vi src/main/org/firebirdsql/jdbc/FBDatabaseMetaData.java
Line 2433 change as CHARACTER_LENGTH to as CHAR_LEN
Line 2642 change CHARACTER_LENGTH to CHAR_LEN

Run the ant build task so generously created to create your
distributable jar files.

I now am using said driver with Firebird 2.0.0 RC1 and all is working
well.

Hope this helps someone.
