problem in getting large object in pooled database

[ahmet temiz]

hello

I try to develop jsf application with pooled postgresql and tomcat 6.

when I try to retrieve large object, I get exception.

here is the code that creates exception:

PGConnection pgCon = (PGConnection)
((DelegatingConnection)conn).getInnermostDelegate();

java.lang.ClassCastException:
org.apache.tomcat.dbcp.dbcp.PoolingDataSource$PoolGuardConnectionWrapper
cannot be cast to org.apache.commons.dbcp.DelegatingConnection


what changes should I made ?
