Why do I get java.lang.AbstractMethodError: oracle.jdbc.driver.OracleConnection error?

I already read Why do I get java.lang.AbstractMethodError when trying to load a blob in the db?, downloaded all of the 11g jdbc drivers I could find, and added them as libraries and/or jar files to my NetBeans application. I still keep getting the same AbstractMethodError and it is driving me batty! Any guidance would be greatly appreciated!

try {

    stmt = conn.createStatement();
    inputFileInputStream = new FileInputStream(inputBinaryFile);  

    Blob vBlob = conn.createBlob();
    BufferedImage vGImage=ImageIO.read(name);
    int offset =0;
    OutputStream out = vBlob.setBinaryStream(offset);
    ImageIO.write(vGImage, "JPG", out);
    PreparedStatement stat = conn.prepareStatement("INSERT INTO item开发者_如何学编程 VALUES (?,?,?,?,?)");
    stat.setString(1, itemNo);
    stat.setString(2, itemName);
    stat.setBlob(3,vBlob);
    stat.setString(4, invenType);
    stat.setDouble(5, vPrice);
    stat.executeUpdate();

} catch (IOException e) {
    System.out.println("Caught I/O Exception: (Write BLOB value - Put Method).");
    e.printStackTrace();
    throw e;
} catch (SQLException e) {
    System.out.println("Caught SQL Exception: (Write BLOB value - Put Method).");
    System.out.println("SQL:\n" + sqlText);
    e.printStackTrace();
    throw e;
}finally {
    conn.close();
}  

The error message:

Exception in thread "main" java.lang.AbstractMethodError:                        
oracle.jdbc.driver.OracleConnection.createBlob()Ljava/sql/Blob;
    at DatabaseIO.setOracleDBBlob(DatabaseIO.java:115)
    at DatabaseIO.main(DatabaseIO.java:26)

The cause of the problem is incompatible software (jar files).

createBlob is a new method (introduced in java 1.6), so older drivers are very unlikely to implement it.

Make sure your classpath only contains compatible drivers, and not any earlier versions of the drivers. (Thanks Jochen)

As others have said this is due to an older Oracle JDBC driver.

In my case replacing ojdbc14.jar (Oracle JDBC driver 10.1.0.5.0) with ojdbc16.jar (Oracle JDBC driver 11.2.0.4.0) fixed the problem.
