Java compiler level does not match the version of the installed Java project facet.
Posted by Redi Gokaj in Eclipse, Java on August 27, 2010
When porting the Eclipse workspace to another computer or another java version there may happen an error like this:
“Java compiler level does not match the version of the installed Java project facet. Unknown Faceted Project Problem (Java Version Mismatch)”
Different solutions can be searched or applied but I would recommend you to check firstly if the JDK is properly installed and after checkcing this you need to right-click to the error and chose Quick Fix. After that there are shown 2 optional choices which one of them is to use your current JDK version. By choosing that you fix your workspace problem.

In order to make PrimeFaces work we need to add to web.xml these:
<servlet>
<servlet-name>Resource Servlet</servlet-name>
<servlet-class>org.primefaces.resource.ResourceServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Resource Servlet</servlet-name>
<url-pattern>/primefaces_resource/*</url-pattern>
</servlet-mapping>
And in order to use PrimeFaces in jsp tags, we need to add the following taglib:
<%@ taglib uri=”http://primefaces.prime.com.tr/ui” prefix=”p” %>

The purpose of this video is to explain a scenario which shows the way how to create a database project using an object oriented approach. Rational Software Architect and Rational Data Architect (Infosphere Data Architect) are used for this tutorial. Using RDA and RSA you may watch this simple tutorial about creating a logical model. After that, converting it to a physical model. The third step will be creating the database, and after that creating the entities mapped with the database. With a sample web application, these entities are used and tested.
