Web Resource Optimizer for Java

wro4j is a free and Open Source Java project which will help you to easily improve your web application page loading time. It can help you to keep your static resources (js & css) well organized, merge & minify them at run-time (using a simple filter) or build-time (using maven plugin) and has a dozen of features you may find useful when dealing with web resources.

Getting Started

In order to get started with wro4j, you have to follow only 3 simple steps.

Step 1: Add WroFilter to web.xml

	<filter>
	  <filter-name>WebResourceOptimizer</filter-name>
	  <filter-class>
		ro.isdc.wro.http.WroFilter
	  </filter-class>
	</filter>
	 
	<filter-mapping>
	  <filter-name>WebResourceOptimizer</filter-name>
	  <url-pattern>/wro/*</url-pattern>
	</filter-mapping>

Step 2: Create wro.xml

	<groups xmlns="http://www.isdc.ro/wro">
	  <group name="all">
		<css>/asset/*.css</css>
		<js>/asset/*.js</js>
	  </group>
	</groups>

Step 3: Use optimized resources

	<html>
	  <head>
		<title>Web Page using wro4j</title>
		<link rel="stylesheet" type="text/css" href="/wro/all.css" />
		<script type="text/javascript" src="/wro/all.js"/>
	  </head>
	  <body>
		
	  </body>
	</html>
