I have some problem when I want to insert BLOB data type to oracle DB
I get the exception following:

java.lang.AbstractMethodError: oracle.jdbc.driver.OracleResultSetImpl.getBlob(Ljava/lang/String;)Ljava/sql/Blob;

at line that I write
Blob blob = resultset.getBlob(1);
or
oracle.sql.BLOB blob = (oracle.sql.BLOB)resultset.getBlob("sample");
when I write each of these 2 lines I get the above exception.

I have used empty_blob() function in this program

I copied my source code here:

public void create() {
    BufferedInputStream in = null;
    OutputStream out = null;

    try {
      // insert a row into the BLOB table, use the empty_blob() construct for
      // the BLOB field. empty_blob() creates the BLOB locator for Oracle
      statement = getStatement(false);
      statement.executeUpdate("INSERT INTO tracksamples (recordingid, tracknumber," +
                              " sample) VALUES (1, 1, empty_blob())");
      // Retrieve the row that was just inserted
      resultset = statement.executeQuery("SELECT sample FROM tracksamples WHERE " +
                                         "recordingid = 1 AND tracknumber = 1 for update");
      if (resultset.next()) {
        // Get the BLOB locator
        oracle.sql.BLOB blob = (oracle.sql.BLOB)resultset.getBlob("sample");
        // Get the output stream which will be used to send data to the table.
        // Use Oracle extension because JDBC 2.0 does not support writing data to BLOB
        //out = ((oracle.sql.BLOB) blob).getBinaryOutputStream();
        out = blob.getBinaryOutputStream();
        // Let driver compute buffer size for writing to BLOB
        //int bufferSize = (int) ((oracle.sql.BLOB) blob).getBufferSize();
        int bufferSize = (int) blob.getBufferSize();
        // Create a buffered stream to read from the file
        in = new BufferedInputStream(new FileInputStream(sampleFile), bufferSize);
        // Create a byte buffer and start reading from the file
        byte[] b = new byte[bufferSize];
        int count = in.read(b, 0, bufferSize);
        // write the bytes using the OutputStream
        // loop until all bytes are written to the table
        System.out.print("Storing data in database.");
        while (count != -1) {
          out.write(b, 0, count);
          System.out.print(".");
          count = in.read(b, 0, bufferSize);
        }
        System.out.print("Complete");
        // Close the Input and Output Streams
        // The Output stream MUST be closed before the commit
        out.close();
        out = null;
        in.close();
        in = null;
        //And finally, commit the changes
        connection.commit();
      }
