To create your own application that uses the Jeenius framework. Simply:
Create a new web application (using your IDE or by hand). See here for more information.
Copy jeenius.jar from the <JEENIUS>\lib directory and place it into the WEB-INF\lib folder of your web application.
In your WEB-INF\web.xml file add the following section:
<taglib>
<taglib-uri>jeenius</taglib-uri>
<taglib-location>/WEB-INF/lib/jeenius.jar</taglib-location>
</taglib>
In your application JSP pages add a taglib directive as follows:
<%@ taglib uri="jeenius" prefix="jee" %>
Then use any of the availble tags such as:
<jee:session/> <jee:includeIf ...>
The full source for the demo application can be found in the <JEENIUS>\demo\xxx_src source folders.
