	I am using ORACLECURSOR in my sqlmap and using the following
TypeHandler code. 

	Here's the sqlmap entry 
	                <parameter property="offerRS"
jdbcType="ORACLECURSOR" javaType="java.sql.ResultSet" mode="OUT"

	And here's the handler code 
	public class RefCursorHandler implements TypeHandlerCallback { 

	        public Object getResult(ResultGetter arg0) throws
SQLException { 

	                this.result = (ResultSet)arg0.getObject(); 
	                return this.result; 

	The statement (ResultSet)arg0.getObject(); takes a long time to
return (even for 2 rows). 

	Do you see any issue with the code? 
	I debugged this and eventually found that the above statement
calls the following method within CallableStatementResultSet

	  public Object getObject(int columnIndex) throws SQLException {

	    return cs.getObject(columnIndex); 

	This in turn calls OracleCallableStatement. This part takes a
long time to return. 

	I am using thin driver. 

	Please suggest. I need to get this resolved ASAP.
