Does dbcp support oracle's extention to the JDBC standard

Question

Hi. I am having trouble using method getCursor() in class OracleCallableStatement. We are using Tomcat 4.1X with dbcp and JVM version 1.4.0. The error message is as follows:
24/Oct/2002 03:56:58:330: Exception: java.lang.ClassCastException: org.apache.commons.dbcp.DelegatingCallableStatement
java.lang.ClassCastException: org.apache.commons.dbcp.DelegatingCallableStatement
at org.test.objects.Test.getCursorResult(Test.java:248)
and the code looks like this:
CallableStatement cs_l = conn_l.prepareCall("{call My_Pkg.test(?,?)}");
cs_l.registerOutParameter(2, OracleTypes.CURSOR);
cs_l.registerOutParameter(1, Types.INTEGER);
ResultSet resultSet_l = ((OracleCallableStatement)cs_l).getCursor(2);
Thanks,
Lily

LilyHi,
i suspect that it might has to do with Oracle's syntax for the string object passed to the prepareCall() callable statement
begin ?:={schema.][package.]function_name[(?,?,...)]; end;
or
begin [schema.][package.]procedure_name[(?,?,...)]; end;
