Listener Problem

created by yasser zairi in JBoss Tools - View the full discussion

can anyone please tell me what's wrong with this:

the listener methode in my bean:

public void listener(UploadEvent event) throws Exception{

UploadItem item = event.getUploadItem();

fichier=new File("/home/zairi/Bureau/fichiertmp.xls");

fichier= item.getFile();

fetch(fichier);

}

the riche faces component :

<h:form>

<h:panelGrid columns="2" columnClasses="top,top">

<rich:fileUpload addControlLabel="Ajouter..."

stopEntryControlLabel="Arreter"

uploadControlLabel="Charger"

clearControlLabel="Supprimer"

clearAllControlLabel="Vider"

fileUploadListener="#{fileUploadBean.listener}"

maxFilesQuantity="#{fileUploadBean.uploadsAvailable}" id="upload"

immediateUpload="#{fileUploadBean.autoUpload}"

acceptedTypes="xls"

allowFlash="#{fileUploadBean.useFlash}">

</rich:fileUpload>

</h:panelGrid>

</h:form>

my web.xml
