p:fileUpload prime faces

Question

The listener doesn't respond to my action:

<h:form>
    <p:fileUpload mode="simple" fileUploadListener="#{ADD.uploadImage}" auto="true"/>
</h:form>

and here is the backing bean:

@ManagedBean
@ViewScoped
public class TestClass {

    public void uploadImage(FileUploadEvent e){
        System.out.println("EVENT");
    }

}

and here is my web.xml:

<web-app version="3.0" 
    xmlns="http://java.sun.com/xml/ns/javaee"

        <session-timeout>
            30
        </session-timeout>
    </session-config>

    <welcome-file-list>
        <welcome-file>faces/index.xhtml</welcome-file>
    </welcome-file-list>
</web-app>

The problem is that the method uploadImage doesn't get called.

What is wrong with my code or what is missing?

Answer 1

If you add the @ManagedBean annotation, the name of the instances of your bean will be the name of your class (with a lower-case first letter). In your example, as the name of your class is TestClass , the name of your bean will be testClass .

So, when you write an EL expression that should invoke a method on this bean, you have to write #{testClass.myMethod} (in your case, this will be #{testClass.uploadImage} .
