java.lang.AbstractMethodError: oracle.jdbc.driver.OracleResultSetImpl.

Hi All,


I am trying to write the jdbc code which is independent to database. I
am trying to access the clob datatype for oracle n mysql.
But I am getting the following xception

javax.servlet.ServletException:
oracle.jdbc.driver.OracleResultSetImpl.getClob(Ljava/lang/String;)Ljava/sql/Clob;

Here is my code

if (dataType.equals("CLOB")) {
System.out.println("inside if");
oracle.sql.CLOB expressionClob = (oracle.sql.CLOB) rs
..getClob("EXPRESSION");
System.out.println("inside");
long clobLenLong = expressionClob.length();
int clobLenInt = (new Long(clobLenLong)).intValue();
System.out.println( clobLenInt);
String expression = expressionClob.getSubString(1, clobLenInt);
}
else {
System.out.println("inside else");
msclob = MYSQLUtil.getBlobString((java.sql.Blob) rs
..getBlob("EXPRESSION"));
}



Am i missing something in my code .


thanks,
Krish
