I am trying to use OraclePreparedStatement from Connection object and its throwing an exception:--

The code line from where this exception arises is:
OraclePreparedStatement pstmt = (OraclePreparedStatement)conn.prepareStatement(sqlString.toString());

conn is the java.sql.Connection object coming from jndi (oracle-xa-ds.xml)

Any suggestions as to where i can be wrong????
