Se você colocou o createTempFiles como false, não pode user o método item.getFile(), pois o arquivo ficou em memoria, não foi salvo. Para pegar o arquivo você teria que usar o item.getData() e criar o File dele, ou simplesmente colocar o createTempFiles como true.

Outra coisa:

File arquivo = new File(newDiretory); //Isso não está criando o diretório!
if(!arquivo.exists())arquivo.mkdirs(); //Isso está criando!

carllacj

Guilherme até ai tudo bem, mas o fato é que não quer nem entrar no metodo, não quer nem imprimir o System.out.println("Entrou…);
que coloquei na primeira linha do codigo!!

Guilherme_Gomes
Guilherme_Gomes

Percebi que você usa o MyFaces além do Richfaces. Eles tem um velho caso de conflito. Os dois precisam de um filtro para tratar os dados da requisição. O filtro que você declarar primeiro no web.xml é o que irá funcionar com upload.

Se você colocar o filtro do MyFaces primeiro, use o upload do MyFaces.
Se você colocar o filtro do Richfaces primeiro, use o upload do Richfaces.

Qualquer coisa, posta de novo.

A sua classe Upload implementa Serializable?
Aparece algum erro na saída?

C
carllacj

Não implementa serializable, e não dá erro algum!!!

C
carllacj

na mesma pagina tem o rich:editor que funciona normalmente!!

Aqui a classe Upload, ta cheia de linhas comentadas, e o metodo q tento chamar no xhtml é o upload.

package idesp.sie.controller;

import java.io.File;

import javax.faces.context.ExternalContext;
import javax.faces.context.FacesContext;
import javax.servlet.ServletContext;

import org.richfaces.event.UploadEvent;

    private int uploadsAvailable = 5;
    private boolean autoUpload = false;
    private boolean useFlash = false;
    public int getSize() {
   /*     if (getFiles().size()>0){
            return getFiles().size();
        }else 
        {
     */       return 0;
       // }
    }

    public Upload() {
    	System.out.println("Entrou");
    }
    
    public void upload(UploadEvent event) {  
    	 System.out.println("entrou uplod metodo");
    	       try {

        file.setName(item.getFileName());
        file.setData(item.getData());
        files.add(file);
       */ uploadsAvailable--;
    }  
      
    public String clearUploadData() {
     //   files.clear();
        setUploadsAvailable(5);
        return null;
    }
    
    public long getTimeStamp(){

O que estou pensando é, por você estar usando o javax.faces.STATE_SAVING_METHOD como client, poderia dar erro se seu bean não implementar serializable!
Se não for isso, é algo realmente estranho, tenta colocar o upload sozinho numa pagina, sem estar dentro de nenhum panelGrid ou qualquer outra coisa.
Já vi do upload do richfaces dar erro em diversas ocasiões quando aninhado em outros componentes!
