Hello,
I read several threads about this problem, but I did not find a solution.
I am using jboss-3.2.3
My code looks like this:
try {
DAOFactory daof = DAOHelper.getDAOFactory();
// The following method acquires a connection
dao = (TreeDAO)daof.getInstance();
// Here I use some objects that
// acquire other connections using DAOFactory
}catch(Exception e){
// Exception handling here
}finally{
// The following method closes the connection
EJBHelper.releaseDAO(dao);
}
Each time, in the same thread, I need to acquire more than one connection, I obtain
the message and the stacktrace below.
The messages are dumped when I try to open the second connection.
Can you help me ?
Bye,
L.
