[Qt-jambi-interest] QSQLite driver for windows

[TieKei]

Hi!
since I am searching the internet for a solution of my problem, I know 
that this may be a annoying question, but
"what should i do to fix the
QSqlDatabase: QSQLITE driver not loaded
QSqlDatabase: aviable drivers:
Error?"

I write my QTJambi program on Linux and it works fine.
After exporting it to an jar file and testing it on another Linux it 
works too. But if I try to run it on Windows XP the complete GUI works 
fine, but with any database access I get the error described above.

I already tried to copy the .DLLs from the QTWin32 packet, but it has no 
effect.
Since my program contains follwoing line:
/QApplication.addLibraryPath(QApplication.applicationDirPath());/ my 
folder structure (in Windows) looks like this:
program.jar, qtjambi.jar, qtjambi-win32.jar and a folder named 
sqldrivers containing com_tolltech_qt_sql.dll ,QtSql4.dll *and* 
qsqlite4.dll (copied from the QT-win32 package)

I think that I have to change a path or something... But I have no idea.
Thank you in advance!
