Join the chat at https://gitter.im/wro4j/wro4j Build Status Maven Central

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>
