Spring Aspects

Spring aspects can work with five kinds of advice :

• Before - The advice functionality takes place before the advised method is invoked.
• After - The advice functionality takes place after the advised method completes, regardless of the outcome.
• After-returning - The advice functionality takes place after the advised method successfully completes.
• After-throwing - The advice functionality takes place after the advised method throws an exception.
• Around - The advice wraps the advised method, providing some functionality before and after the advised method is invoked.

10038 Jolly Jumpers

Problem E: Jolly Jumpers

A sequence of n > 0 integers is called a jolly jumper if the absolute values of the difference between successive elements take on all the values 1 through n-1. For instance,

1 4 2 3

is a jolly jumper, because the absolutes differences are 3, 2, and 1 respectively. The definition implies that any sequence of a single integer is a jolly jumper. You are to write a program to determine whether or not each of a number of sequences is a jolly jumper.

Input

Each line of input contains an integer n <= 3000 followed by n integers representing the sequence.

Output

For each line of input, generate a line of output saying "Jolly" or "Not jolly".

Sample Input

4 1 4 2 3
5 1 4 2 -1 6

Sample Output

Jolly
Not jolly

Accessing Spring in Generic Web Applications

A web application can load Spring's application context be registering the servlet listener ContextLoadListener. This listener stores the loaded application context into the web application's servlet context. Later, a servlet, or any object that can access the servlet context can access the Spring's application context through the WebApplicationContextUtils.getRequiredWebApplicationContext() method.

Oracle JDBC Driver

Oracle Note : The Java classes to connect to Oracle are contained in the Oracle JDBC driver jar file. For recent releases, these are numbered based on the Java version they are compiled for, such as ojdbc14.jar (for Java 1.4), ojdbc15.jar (for Java 1.5), etc.
