I think project task is a good example. See developmnt DOCO.

Some JDBC drivers are not 3.0 compliant (Sybase) so it needs to know
table name. When I have time to retest it, I will remove.

Yes.

I do use poolman. But maybe switch to tomcat's dbcb.

It is great for composite objects. You can do it with SQL join, since it
supports ANY sql command.
And:
You can have a bean that contains a bean.
So you would have a person bean. And it contains address bean.
So you would say personBean.getAddressBean().getCity().
It works great on jsp.

Once I have a larger comunity, I plan to donate to Jakarta.
Everyone should use DAO interface, so people can implement DAO any way
the see fit.
