[DAS] Tuscany-863 - create/init of canned DB if not already present

[Amita Vadhavkar]

Hi All,
Below is the link for the JIRA-
https://issues.apache.org/jira/browse/TUSCANY-863

Using servlet init params, we can expand the current sample (companyweb) to
use
different DAS config xmls for demonstrating different DAS features.

Any thoughts?

Regards,
Amita
