This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Note that it's not a good practice to mix Java/JDBC code and JSP. The JDBC should be in a servlet (or class called from a servlet) and then forward to a JSP. It is harder to develop, troubleshoot, maintain and reuse code in a JSP. Which wil negatively impact getting it working.
In any case, what error do you get when you try to run your code?
Also, you should only have one try/catch. If an exception is caught, it doesn't make sense to continue.
