Troubleshoot and fix java application's mysql connection.

I have a java application that will monitor stock prices and update a mysql database during the day. My code establishes the connection and will update/insert 1 record but on the next iteration it crashes and says the connection is closed. I need someone to access my computer through TeamViewer and fix this issue as well as help me with some sql related try/catch statements.

Here is the error I am getting after the first iteration successfully inserts/updates the mysql database: Could not get mysql datasource:Data source is closed

[login to view URL]: Data source is closed
