在AIX系统中从mySQL数据库检索数据时出现问题

Question

I am trying to retrieve data from MySQL database table. To do that, I use following code on various platforms. My code works perfectly on Windows and Linux platforms. But when I use same code in AIX 6.1, it does not retrieve correct data.

The Main Function:

String storedstring = objDBUtil.lookup(0);
logger.info(storedstring);

The Database Util Function:

public String lookup(String number) throws Exception {
    String sql = "SELECT info FROM records WHERE Snumber=?";

    Connection dbConn = connect();
    try {
        PreparedStatement stmt = dbConn.prepareStatement(sql);

    try {
           stmt.setString(1, number);

           ResultSet rs =  stmt.executeQuery();

            try {
                if (!rs.next()) {
                    throw new TException("does not exist in the database");
                }
                return  rs.getString(1);
            } catch (Exception e) {
                logger.info("Unexpected exception caught during auth: " + e.getClass().toString() + " " + e.getMessage());
                return null;
            }finally {
                rs.close();
            }
        } finally {
            stmt.close();
        }
    } finally {
        dbConn.close();
    }
}

Output of the main function on Windows, I get the entire string from the database. But exact code gives me encrypted value on AIX machine.

Output on AIX machine [B@62637268

I resolved the issue. Issue was with connector file. I was using older version of connector file.

MySQL version I was using: mysql-5.5.2-m2-aix5.3-powerpc-64bit

Non working version of Mysql connector with above mysql: mysql-connector-java-3.1.7-bin.jar

Working version of MySQL connctor with above mysql: New version: mysql-connector-java-5.1.6-bin.jar

Thank you everyone for looking into my question and trying to help me. Really appreciated.
