Hello, I use a C3P0 Connection Pool, but, i have many problems, because my connections pools need to be created dinamically. I do test with connection pool of JBoss and my problems disappear. The question, is that i need create a pool, in other words, instantiate a DataSource and bind to JNDI, dinamically, and i would like that this connection pool (DataSource) was the JBoss pool. I can't create a -ds.xml file, because my information to connection don't exist in startup time of JBoss. I tried instantiate a WrapperDataSource, but, this class need for two parameters: "final BaseWrapperManagedConnectionFactory mcf, final ConnectionManager cm", and i don't known how do i do. Somebody help me? Regards. Ezequiel View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4040412#...
