Establish connection between app server and oracle database using java

I have been given a task to write a script in java, to connect oracle database from an app server. Scheduling tool will be used to schedule the job every 10 minutes.

If connection exists, the script will do nothing and just disconnect it. (and will be run again after 10 minutes). If cannot connect after 10 secs, the program will send an email notification.

The whole thing is to ensure connection can be established between the app server and the oracle db.

Really have no clue on this. Could you please advise what are the steps to do this and what Java APIs I'll need??

Many many thanks in advance!
