 <h3 class="heading-1">Example Directory Structure
</h3><p class="paragraph"/>The following is one example of a web application directory structure that can be used to configure WebWork 2 in your application. 
<ul class="star">
</ul><p class="paragraph"/>For more information about the web.xml file, see <a href="webconfig.html">Configuring web.xml</a>.<p class="paragraph"/>WebWork 2 has a number of required and optional libraries that must be included in the WEB-INF/lib folder for certain features of the framework to work correctly.<p class="paragraph"/>Required libraries:
<ul class="star">
<li>commons-logging.jar (this is the logging library used in webwork2)</li>
<li>ognl-2.5.1.jar (this is the OGNL library used for webwork2's expression language)</li>
<li>oscore-2.2.1.jar (contains core functionality that is reused in webwork2)</li>
</ul><p class="paragraph"/>Optional libraries:
<ul class="star">
<li>cos-multipart.jar (only required if you need cos multipart support)</li>
<li>pell-multipart.jar (only required if you need pell multipart support)</li>
<li>velocity-dep-1.3.jar (only required if you use the webwork2 tag libraries)</li>
</ul><p class="paragraph"/>Note that commons-logging will pick a specific log implementation only if it finds the correspondent classes on the classpath. So, if you want commons-logging to use <span class="nobr"><img src="http://wiki.opensymphony.com/images/external-link.png" alt="&gt;&gt;" border="0"/><a href="http://jakarta.apache.org/log4j">Log4J</a></span> as the actual log implementation, you need to put the log4j.jar file in the WEB-INF/lib folder as well.
