What others library need to include to make fileUpload work

[KingdomHeart]

I forgot what other jar file that I need to include to make fileUpload work? It like io.jar ...

Is it posible to do this?

Code: Select all

                    <p:fileUpload fileUploadListener="#{EditNetwork.handleFileUpload}" update="msgs">
                        <f:param name="location" value="TestLocation"/>
                    </p:fileUpload>

Code: Select all

    public void handleFileUpload(FileUploadEvent event, String location) {
        FacesMessage msg = new FacesMessage("Succesful", event.getFile().getFileName() + " is uploaded. Location: " + location);
        FacesContext.getCurrentInstance().addMessage(null, msg);  

    }
