ADF 11g application on Weblogic 10.3 + JDBC connection to Oracle XE

Question

Hello! i'm using Jdev 11g (not tp4) and i have Adf applicarion which uses BC4J, thereofre in jdev exists connection to DB.
When i start my application in Jdev, it starts Weblogic and deploys my application. And all works fine!
When i want to execute my Weblogic as standalone server, using Weblogic domain Administration console, i deploy my application as WAR archive
before deploy, i've been created JDBC DataSource in Weblogic server, using Weblogic webinterface (connection test was OK)
and now, when i start my application, entering application Url in internet explorer, i see that exception has ariced, her is the stack trace

in BC4J project Model.jpx tells that bc4j uses connection named Nano_DB_connection.
in Weblogic datasource name is the same
Question: how to bind my application in weblogic to existed connection/datasource in weblogic?
how Jdev deploys and configures Weblogic server, that it works fine, but when i start THE SAME server manually, deploy application using JDEV the application execution failed (see above exception)
maybe i should use EAR profile instead of WAR, to deploy all connections and other stuff to weblogic?
{color:#ff0000}please help!!!{color}

Answer 1

Hi,
Did you configure your application module to use a JDBC data source? To do this, right-click the app module in the navigator, select Configurations and in the dialog that comes up change the connection type to JDBC Data Source and enter your data source name - which should be the same as the data source you created on the weblogic server.
Also, I do suggest you create an EAR file - this is what we've tested and certified with. You can find more details in the deployment chapter of the fusion developer's guide: http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/deployment_topics.htm#CHDJJDDG.
Hope this helps
