After deploying the Oracle BC4J using a Datasource as DB connection I run a client that access the beans.
When the application module tryes to connect the DB I become the following runtime error:

With Bea (WLS) and OC4J it is not necessary to make a separate DB connection with the "am.getTransaction().connectToDataSource( env, "java:/ScottTigerDS", false );" statement.
