To use the tags, you need to do the following:

1. Place the layout.jar file in the classpath of your project.
2. Create a tld file that refers to the tags and place it in the WEB-INF directory of your web application. A tld file called layout.tld for JSP version 1.1 is found in the project download. You can use that one or write your own. Future releases will contain a sample tld file for JSP version 1.2.
3. Create an entry in your web.xml file that refers to the tld file, as per the JSP specs. It should be similar to the following:

<taglib>
    <taglib-uri>/WEB-INF/layout.tld</taglib-uri>
    <taglib-location>/WEB-INF/layout.tld</taglib-location>
</taglib>

4. At the top of each JSP page that will use the Layout Tag Library custom tags, add a line declaring the Layout Tag Library like this:

   <@ taglib uri="/WEB-INF/layout.tld" prefix="layout" %>

5. To control the logging level of the library, place an appropriate log4j.properties files in WEB-INF/classes.
