Connection reset when inserting file to BLOB column

Question

Friends,
When inserting a file to a BLOB clomun and the file is more than 1KB, I receive the following message: java.sql.SQLException: Io exception: Connection reset
The code is this:
int fileLength = (int)file.length();
System.out.println("File length: "+fileLength);
int cod = (int)(Math.random() * 1000);
String sql = "INSERT INTO BLOB_TABLE VALUES(?,?)";
try {
FileInputStream fis = new FileInputStream(file);
PreparedStatement pstmt = connection.prepareStatement(sql);
pstmt.setInt(1, cod);
pstmt.setBinaryStream(2, fis, fileLength);
pstmt.executeUpdate();
System.out.println("File insert sucess!");
connection.close();
Does anybody know what this can be? My database is oracle.
Thanks!

When you create objects on the database they are stored in the data dictionary by default in UPPER case.
So in this line:
src_loc bfile := bfilename('example_lob_dir', 'example.gif'); -- source location
you need to reference the name of the directory object in upper case. e.g.
src_loc bfile := bfilename('EXAMPLE_LOB_DIR', 'example.gif'); -- source location
