Java.lang.AbstractMethodError (rs.getBigDecimal)

Question

Hello,
I consistently get a java.lang.AbstractMethodError when I call getBigDecimal() on a ResultSet, as in the example below. I recently downloaded and installed the latest classes12.zip, but this did not help.
I am connecting to an 8.1.6 server.
Thanks in advance for you help.
try
     conn = DriverManager.getConnection(jdbcUrl);
     conn.setAutoCommit(false);
     stmt = conn.createStatement();
     // get the first set of profiles
     log.debug("Executing statement: " + sqlText);
     rs = stmt.executeQuery(sqlText);
     log.debug("Statement executed ok. Now parsing rows...");
     while (rs.next())
     ProfileKeys keys = new ProfileKeys();
     keys.emailAdr = rs.getString("EMAIL_ADR");
/* code fails on this statement */
     testBD = rs.getBigDecimal("CUST_ID");
     keys.custId = testBD.longValue();
     keys.custId = rs.getBigDecimal("CUST_PRFL_NUM").longValue();
     profiles.add(keys);
     count++;
     if (conn != null) { conn.close(); }
     log.debug("Found " + count + " rows.");
catch (SQLException e)
     e.printStackTrace();
     while(e != null)
     log.error("NewsletterProfileImporter.getRecords(): ");
     log.error("\nSQL Exception:");
     log.error(e.getMessage());
     log.error("ANSI-92 SQL State: " + e.getSQLState());
     log.error("Vendor Error Code: " + e.getErrorCode());
     e = e.getNextException();
     log.error("Terminating Connection to database.");
     conn.close();

Hi Stewart,
You can try these following options.
1. Try casting your rs.getBigDecimal(columnName) with java.math.BigDecimal and then assign to testBD which hopefully would be of type java.math.BigDecimal. see if this helps.
or 2. instead of jdbc's resultset, use the result set of Oracle's. This is available in oracle.jdbc.driver package. and the class Name is OracleResultSet
i.e create ur resultset as following.
import oracle.jdbc.driver.*;
OracleResultSet rs = null;
rs = stmt.executeQuery(sqlstmt);
now
java.math.BigDecimal testBD = rs.getBigDecimal(columnName);/cast to big decimal if necessary.
Reason, this might work because, Oracle's OracleResulSet class has this getBigDecimal(java.lang.String) method already implements, JDBC 2.0's getBigDecimal function.
you may be aware that getBigDecimal(int) is an abstract method and cannot be used directly. so getBigDecimal(String) is the viable option.
Hope this helps.
Thanks
