create OSGI configuration dynamically

HI,

I need to create a JDBC configuration dynamically like build time. 

This can be using either OSGI config API  or properties etc..

Any help would be appreciated.

# Configuration created by Apache Sling JCR Installer
jdbc.password="XYZZZ"
jdbc.driver.class="com.microsoft.sqlserver.jdbc.SQLServerDriver"
datasource.name="testjdbc"
jdbc.connection.uri=""
jdbc.validation.query=""
datasource.svc.properties=[""]
default.readonly=B"false"
default.autocommit=B"true"
jdbc.username="app_optout"
pool.size=L"50"
pool.max.wait.msec=L"20000"
