How to bind ascii stream to a prepared statement

I am testing fastload example code from an official teradata website . To err on the side of caution , I use the sample FastLoad1.csv located on their samples.jar here

When I run this sample code, I get an error in this line

  pstmtFld.setAsciiStream(1, dataStream, -1); // This method is not implemented

How must setAsciiStream be used with a prepared statement ?

Am i using the setAsciiStream correctly ?

Here is the error message in console

 Attempting connection to Teradata with FastLoadCSV.
 Connection to Teradata with FastLoadCSV established.
 Creating a PreparedStatement object with FastLoadCSV.

I tried to compile the example T20208JD, just modified DNS/user/password and it run smoothly on my Mac. So pstmtFld.setAsciiStream(1, dataStream, -1); seems to be correct.

I used JDBC 14.10.00.18, you might try to download the latest version 14.10.00.26 from Teradata's Developer Exchange: http://downloads.teradata.com/download/connectivity/jdbc-driver

I don't think this will fix the problem, but...

I think the error is caused by the -1, the third parameter, which tells setAsciiStream that the byteStream has -1 bytes.

When I have used setAsciiStream() in the past, I used a bufferInputStream and the the size of a String if it was over 254 characters.

    String convRule;
     ...
    if (convRule.length() > 254) {
        int size = convRule.length();  
        BufferedInputStream bais = new BufferedInputStream( new ByteArrayInputStream( convRule.getBytes() ) );  
        pStmt.setAsciiStream( 4, bais, size );
    }

So, comparing mine to yours I can tell the third parameter is different which should be the length of the input stream.
