Jar, War and Ear files

Jar, War and Ear files are essentially the archived files. There are no structural differences among the three types, though these are intended for different purposes.

Jar: Jar files (Java Archive file : .jar extension) stores of Java classes, resources, auxiliary files, etc. Java source files are compiled and then distributed in jar format.

War files (Web Archive File : .war extension) are intended to contain complete Web applications. A Web Application is a collection of files, classes, resources, .jar files that can be packaged and accessed as one servlet context. Usually, sample web applications are distributed using war format.

Ear files (Enterprise Archive file : .ear extension) are intended to contain complete Enterprise applications. In this context, an enterprise application is defined as a collection of .jar files, resources, classes, and multiple Web applications.

All three types of files can be generated using Ant.

JSP Performance Tips

Here are a few tips to improve JSP performance that I have been using. If you have your own listing of the tips, plz share. Disable JSP auto reloading feature. Use thread pool for your JSP engine and define the size of thread pool as per application requirement. Use jspInit() method to cache static data Initialize the 'out' object (implicit object) with proper size in the page directive. Set the content length Give 'false' value to the session in the page directive to avoid session object creation.

Use print() method rather than println() method Use ServletOutputStream instead of JSPWriter to send binary data Minimize code in the synchronized block Do not use custom tags if you do no...

How old are the daughters?

Two MIT math graduates bump into each other at Fairway on the upper west side. They hadn't seen each other in over 20 years. The first grad says to the second: "how have you been?" Second: "Great! I got married and I have three daughters now" First: "Really? how old are they?"
