False File.exists; flex cannot open SQLite.db file

Question

I have a program that uses an SQLite database. Instead of creating and importing the database, the sqlite databse already exists, with the data.
I am trying to open it and read the information (select* from table - for example); But nothing i do seems to work.
The error I am getting is: 'Error #3125: Unable to open the database file.', details:'Connection closed.', operation:'open', detailID:'1001'. I have checked the path repeatedly, The file exists. I run flash builder as administrator (win7).
code:
I have moved the database file all around. In the final version of the program, the database will be stored in a seperate drive on a network (Z:/database.db, for example) So i need to use the absolute path; although i have tried others (application storage directory, etc)
var dbFile:File = new File("C:\Users\Public\Documents\graduates.db");
trace('exists:' + dbFile.exists);
//above being the important bit.
dbStatement = new SQLStatement();
dbStatement.itemClass = Grad;
aluDB = new SQLConnection();
dbStatement.sqlConnection = aluDB;
aluDB.addEventListener(SQLEvent.OPEN, onDatabaseOpen);
aluDB.addEventListener(SQLErrorEvent.ERROR, errorHandler);
aluDB.open(dbFile);//error occurs here, of course.
can anybody help me figure out why this error is occuring? Or even just a different method of opening the file?

Hello,
I have an Oracle Express Edition 10g running on
Redhat Enterprise Linux 4 server.
I have an Oracle database file which is 2.1 GB in
size. I am not able to open this file using the
application or the Oracle sql developer. The error
message that I get is:
ORA-01110: data file 5:
'/usr/lib/oracle/xe/oradata/XE/service_3_0.dbf'
ORA-27041: unable to open file
Linux Error: 13: Permission denied
I think this has to do with the fact that since it is
not a 64-bit Linux but a 32-bit Linux, it does not
support files larger than 2GB. What do you think I
should do to tackle this problem?

ThayalanThat's interesting! I had no problems with opening files 32767MB in size on the very same 32 bit RH EL 4.0. How did you conclude that your file is too large, based on the error message which reads "Linux Error: 13: Permission denied"? Have you tried reading the manual page for the "open" system call and see when does it return EACCESS (error 13), found in /usr/include/asm-i386/errno.h. My man page for open says the following:
ERRORS
EACCES The requested access to the file is not allowed, or search per-
mission is denied for one of the directories in the path prefix
of pathname, or the file did not exist yet and write access to
the parent directory is not allowed. (See also path_resolution(7).)
What lead you to the conclusion that your file is too big? Do you have an access to a system administrator who knows how to use "strace"? If your system admin doesn't know how to use "strace", he too deserves waterboarding.
