How to pass url parameter string to a query

Question

I need urgent help please, to pass a mysql query string from a master page to another details jsp page using a url parameter. The master page's url parameter looks like this;
<a href="Details.jsp?jobs=<c:out value="${row.actions_id}"/>"><c:out value="${row.action_title}"/></a>How can I query the mysql database using the url query string to get the query details.
Please help me out with detailed example please.

You can get the parameter value using HttpServletRequest#getParameter():String jobs = request.getParameter("jobs");You can interact with databases using the JDBC API. This is a different topic. If you aren't familiar with it yet, then learn it. There is a very good JDBC tutorial here at Sun.com: [http://java.sun.com/docs/books/tutorial/jdbc/index.html]. Once you're familiar with that, create a DAO class which does the all the database interaction tasks. Create a method which takes the jobs value as parameter and let it return result(s) accordingly.
