javax.el.PropertyNotFoundException

HI,

I made a template in the Web Pages/WEB-INF/templates/default.xhtml and that template had one <ui:insert name="content"> and also some links that will be active with the controllerBean. But when I click on the commandLink (for example: <h:commandLink value="Facturen" action="#{controllerBean.facturen}" styleClass="facturen"/>) I get this:

Stack Trace

What did I wrong?

Hello,
I havent worked much with JSF but these are the questions that would help you resolve the issue.
1) Where is the mapping for "controllerBean" that is used in your code.
2) Also make sure to check if package "Beans" also specified as your "controllerBean" is inside the package "Beans".

Regards,
amit

The first one I doesn't understand, but my controllerBean is in the package bean.

You have violated the Java Standard Naming convention by starting a class name with a lower-case character. The default mechanism used by JSF's annotation processor mandates that the classname must follow the standard, which means that the class name must be "ControllerBean", not "controllerBean". JSF will then instantiate the bean and catalog it under the object name "controllerBean" (starting with lower-case, as is the standard for class instances).

Incidentally, in the MVC paradigm, backing beans are NOT controllers. They are Models, although they may be lightly decorated with controller assists such as listeners. The actual Controller part of JSF is primarily located in the FacesServlet and the various tag implementations, and relatively little user-written Controller code is required.
