Many times while using WordPress, if we try to use “$” to access jQuery, we get an error the “$ is not defined”. This happens because the jQuery library which is included in WordPress loads in “no conflict” mode. In the no conflict mode jQuery returns the control of “$”, and it is no longer accessible as a function, variable, or alias for jQuery. WordPress does this in order to prevent compatibility problems with other JavaScript libraries that can be loaded.
Apache™ Hadoop® is an open source software project that enables the distributed processing of large data sets across clusters of commodity servers. It is designed to scale up from a single server to thousands of machines, with a very high degree of fault tolerance. Rather than relying on high-end hardware, the resiliency of these clusters comes from the software’s ability to detect and handle failures at the application layer.
Hadoop 1 popularized MapReduce programming for batch jobs and demonstrated the potential value of large scale, distributed processing.
What’s HTTP? HTTP stands for Hypertext Transfer Protocol. It’s the network protocol used to deliver virtually all files and other data (collectively called resources) on the World Wide Web, whether they’re HTML files, image files, query results, or anything else. Usually, HTTP takes place through TCP/IP sockets (and this tutorial ignores other possibilities).
A browser is an HTTP client because it sends requests to an HTTP server (Web server), which then sends responses back to the client.
It’s quite straightforward to integrate Log4j into the Spring MVC application. First, include Log4j.jar library into your project dependency, then create a log4.properties file to define the Log4j’s appender and put this file into the project classpath, Done.
In the tutorial, we show you how to integrate the Log4j 1.x logging framework into the Spring MVC application.
Add Log4j Library to Your Project Download the Log4j library from the official website, or via Maven :
Ajax is a term coined by Jesse James Garrett and that became popular since the publication of the article Ajax: A New Approach to Web applications, published in February 2005, is a shortcut for Asynchronous JavaScript and XML.
The normal behavior of the Internet that involves sending pages to the browser is completely changed by the use of Ajax.
Ajax has become commonplace with its integration in HTML 5 and JavaScript frameworks, and in fact, the interest of developers has moved to HTML 5 for its new tags and APIs that accompany it.
After all the services, DAO, and support classes are tested then it’s time for the controller. Generally, this is hard to test and most developers (based on observation) would rather just test it via Selenium or worse, by hand. That can work but it makes testing logic branches difficult and not to mention it’s time-consuming. Plus no active developer would be willing to wait for browser tests to run before checking in code.
In this tutorial, you will learn how to develop a Spring 4 MVC Hello world example. We hope this tutorial will give you a quick start with Spring MVC development using the latest Spring 4 Release.
Technologies used:
Spring 4.0.4.RELEASE JDK 1.8 Tomcat 7.0.53 Maven 3.2.1 Eclipse Java EE IDE ( Eclipse Kepler) Maven Project Setup In Eclipse Let us start with the creation of a Maven web project in Eclipse.
In this tutorial we are going to describe Jenkins installation and configuration with Maven and GitHub. We are going to use a Tomcat Application Server 7. If you don’t have Tomcat installed please get one here. You will need a Java 7+ SDK installed as well
Git binaries installation At first we need client tool using which git operations like cloning, fetching, pooling can be done. We have chosen git client implementation available at git-scm.
