BFILE Problem

Question

Hello,
The problem that i have is that i want to insert a file residing in the network into the oracle database into a blob field and again read it from the database and show it ie either insert it into a file directly and then open it using the correct editor or open it directly. I am using java along with it but i am basically stuck on the database side.
I am sending the code which i have written till date
i basically need to know
1)the syntax i am using to interact with the database is right ie where is the error in the code
2)provided that is ok whether my overall code is on the right track.
After line control 10
The error message i am getting:
java.sql.SQL Exception:ORA-22288:file operation fileopen failed
LFI:00108:open expect the file[map][gif] to exist
ORA-0615:at"SYS.DBMS_LOB",line 370
ORA-0615:at line 1
My developopment enviornment is JDeveloper3.0 as this code is having problems compiling in JDK as Jdeveloper overides a few of the jdk classes.
