RandomAccessFile on Server.. Where is File Located???

Question

Hello Professionals:
I have created an oracle trigger on a table on insert that passes the column contents to a java procedure that is intended to write this data to a RandomAccessFile. I am not sure where the file will be created on the Server. I created my java classes on an Oracle 8.1.6 database. My java class (and procedure) that writes the data to the file is indicated below. Your guidance is needed. Thanks. I am logged into the database as teh schema owner of the table and java classes.

Chris,
i have posted a response on the JDeveloper forum which says:
The file will be created with a root of $ORACLE_HOME ifthe filename is not
an absolute path. The writer must have the proper permissions to write the
file. All subdirectories, if any in the path name, must exist or an
exception will be thrown.
