[OJB-developers] About connection pool and preparedstatement cache

[John W. <hw...@re...>]

I noticed that for a class, it  can only use the same connection, even for
different users. So when 2 users are accessing the same class objects, they
will share the same connection, and may cause some problem, right?

In ConnectionManager.getConnectionForClassDescriptor, it will get from
hashmap, so it will return the same for a classdescriptor.

The preparedstatement is also cached in the StatementsforClass, which is
good. I am just wondering whether it can live outside of a connection.

Thanks a lot,
John W
