title: Writing a custom jdbc driver in java a very basic one
body: <p>I have web service which I need to expose through JDBC due some BI tools software restrictions. <br>
  Very limited support required few defined select queries.<br>
  What I understand that I need to implement all the classes under the interface java.sql to achieve that. Has anyone done similar things?<br> Do we have some custom implementations where we need to implement the bare minimum code.</p>
