I figured it out. I had followed Tomcat documentation while doing this.
The Oracle example in the documentation mentioned url as
jdbc:oracle:thin:[EMAIL PROTECTED]:1521:mysid
Following that I specified my url as
jdbc:oracle:thin:[EMAIL PROTECTED]:1521:rep while actually it should be
jdbc:oracle:thin:[EMAIL PROTECTED]:1521/rep
With that change, it worked!
