While dealing with current URL, many time you want to know what is the current URL path, What are the parameters, and what is the hash tag on URL. Hash tag is pretty important, if you are implementing tab structure using HTML and JQuery. To avoid confusion, let's take an example of URL: http://javarevisited.blogspot.com/2013/01/top-5-java-programming-books-best-good.html#ixzz2PGmDFlPd, in this example ixzz2PGmDFlPd is hash tag. Now, both JavaScript and JQuery provides convenient way to retrieve current URL in form of window.location object. You can use various properties of window.location JavaScript object e.g. window.location.href to get complete URL, window.location.pathname to get current path, and window.location.hash to get hash tag from current URL. If you like to use JQuery then you can get window.location as JQuery object and retrieve relevant properties using attr() function. If you are absolutely new in JQuery, and unaware of power of one of the most popular JavaScript framework, Head First JQuery is a good starting point. Being a fan of head first book, I always approach a new technology by an Head first title, it helped to learn a lot in short time, without spending time in trivial examples. By the way, In this web tutorial, we are going to retrieve current URL and hash tag using JavaScript and JQuery.

Spring Framework Tutorial How to call Stored Procedures from Java using IN and OUT parameter example
Spring Framework provides excellent support to call stored procedures from Java application. In fact there are multiple ways to call stored procedure in Spring Framework, e.g. you can use one of the query() method from JdbcTemplate to call stored procedures, or you can extend abstract class StoredProcedure to call stored procedures from Java. In this Java Spring tutorial, we will see second approach to call stored procedure. It's more object oriented, but same time requires more coding. StoredProcedure class allows you to declare IN and OUT parameters and call stored procedure using its various execute() method, which has protected access and can only be called from sub class. I personally prefer to implement StoredProcedure class as Inner class, if its tied up with one of DAO Object, e.g. in this case it nicely fit inside EmployeeDAO. Then you can provide convenient method to wrap stored procedure calls. In order to demonstrate, how to call stored procedures from spring based application, we will first create a simple stored proc using MySQL database, as shown below.
