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:

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

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

What is wrong with my code or what is missing?

is your form got enctype="multipart/form-data" , like this : — Daniel, Apr 01 '12 at 12:00

it can't find your upload dir... try changing into /tmpDir3 (removed one / ) — Daniel, Apr 01 '12 at 12:04

Are you looking at the right bean? Your binding says `#{ADD.uploadImage}`, but the bean you've shown will be called `testClass`, NOT `ADD`. — Arjan Tijms, Apr 01 '12 at 12:59

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}.

See: http://docs.oracle.com/javaee/6/api/javax/faces/bean/ManagedBean.html
