Data dictionary for jdbc

Question

hi guyz
I need some help!!
I have created a table in a data dictionary project.
Please let me know how to deploy it. Do you have to deploy it through an ear file or so?
Next, since its on the portal database i heard that we need to use the default datasource.
What is the name of the datasource? Has any setting to be done to use it and please show me 2-3 lines of code on how to use it in order to establish a JDBC connection.
Thanks.
