FileUpload PrimeFaces

Amigo já pensou em usar actionListener ao invés do action? Acredito que irá funcionar

Caso tenha maiores duvidas consulte o portal do primeFaces

http://www.primefaces.org/showcase/ui/fileUploadSimple.jsf

Bom dia já vi sim o ShowCase do PrimeFaces e já tentei também com o actionListener, porém ao acionar o botão do FileUpload o evento não é disparado e não consigo nem pegar o event.getFile() e nem setar o arquivo no UploadedFile que sempre fica null. Mesmo se eu colocar um valor que não existe na propriedade value ou fileUploadListener não da erro pq o método não esta sendo chamado veja abaixo código teste que fiz utilizando o actionListener:

public void fileUp(FileUploadEvent event) { FacesContext fc = FacesContext.getCurrentInstance(); fc.addMessage(null, new FacesMessage("Mensagem", "Arquivo escolhido "+ event.getFile().getFileName())); }

<h:form enctype="multpart/form-data"> <tr> <td><b>Anexar arquivo</b></td> <td><p:fileUpload styleClass="campo" fileUploadListener="#{fileUploadController.fileUp(event)}" label="Escolher Arquivo" mode="advanced" auto="true"/></td> </tr> <tr> <tr></tr> <td><p:commandButton id="anexar" value="Anexar" ajax="false" action="#{fileUploadController.send()}"/></td> </tr> </h:form> <p:growl id="growl" showDetail="true"/>

cara qual versão do JSF voce esta usando?
Dependendo qual for isso aqui não existe send ‘()’
certo

action="#{fileUploadController.send}"

Estou usando a Versão 2.2 e já fiz das duas maneiras e só não funciona o FileUpload.

outro erro

<h:form enctype="multpart/form-data">

o certo é multipart/form-data logo

<h:form enctype="multipart/form-data">

Eu faria assim caso nao funcione verifique mapeamentos do projeto

<h:form enctype="multipart/form-data">  
            <tr>  
                <td><b>Anexar arquivo</b></td>  
                <td><p:fileUpload value="#{fileUploadController.file}" mode="simple"/></td>  
            </tr>  
            <tr>  
                <tr></tr>  
                <td><p:commandButton id="anexar" value="Anexar" ajax="false" actionListener="#{fileUploadController.send}"/></td>  
            </tr>  
        </h:form>  
        <p:growl id="growl" showDetail="true"/>  
    </h:body>

public class FileUploadController {  
  
    private UploadedFile file;  
  
    public UploadedFile getFile() {  
        return file;  
    }  
  
    public void setFile(UploadedFile file) {  
        this.file = file;  
    }  
  
    public void send(){  
        if(file != null) {  
            FacesMessage msg = new FacesMessage("Succesful", file.getFileName() + " is uploaded.");  
            FacesContext.getCurrentInstance().addMessage(null, msg);  
        }  
    }  
}

Agora estou recebendo o erro abaixo:

Agora meu irmão e botar pra debugar e ver o que ta nullo. Seu erro agora é mais tranquilo ‘nullPointExeception’

Ta muito estranho isso aqui coloquei para debbugar e esta acontecendo o seguinte, escolho o arquivo e aciono o commandButton para fazer post dai ao envés da propriedade value="#{fileUploadController.file}" do FileUpload chamar o setFile do meu managedBean ele ta chamando o getFile e por isso o UploadedFile continua null.

Olá Galera descobri que o NullPointerException que esta ocorrendo ao executar o commandButton do FileUpload esta ocorrendo por causa de um bug no GlassFish 4.0, vejam o log abaixo. Tentei com os servidores GlassFish 3.1, GlassFish 3.1.2.2 e JBoss AS 7.1.1, porém os nos ManagedBeans que estão utilizando CDI aparece a seguinte mensagem:

O Artefato CDI foi localizado, mais não há arquivo beans.xml

Alguém tem alguma solução mesmo que não seja com o GlassFish?

segue abaixo um exemplo:

package br.com.comprev.sisprev.bean;

import java.io.File;
import java.io.FileOutputStream;
import java.io.Serializable;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
import javax.faces.context.ExternalContext;
import javax.faces.context.FacesContext;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletResponse;

import org.primefaces.event.FileUploadEvent;

@ManagedBean(name = "fileUploadMB")
@ViewScoped
public class FileUploadMB implements Serializable {

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	public void fileUploadAction(FileUploadEvent event) {
		
		try {
			
			ExternalContext externalContext = FacesContext.getCurrentInstance()
					.getExternalContext();
			HttpServletResponse response = (HttpServletResponse) externalContext
					.getResponse();

			FacesContext aFacesContext = FacesContext.getCurrentInstance();
			ServletContext context = (ServletContext) aFacesContext
					.getExternalContext().getContext();

			String realPath = context.getRealPath("/");
			//String realPath = "C://";

			
			// Aqui cria o diretorio caso não exista
			File file = new File(realPath + "/fotos/");
			file.mkdirs();

			byte[] arquivo = event.getFile().getContents();
			String caminho = realPath + "/fotos/"
					+ event.getFile().getFileName();

			// esse trecho grava o arquivo no diretório
			FileOutputStream fos = new FileOutputStream(caminho);
			fos.write(arquivo);
			fos.close();

		} catch (Exception ex) {
			System.out.println("Erro no upload de imagem" + ex);
		}
		
		
	}

}

<p:fileUpload id="upload"
					fileUploadListener="#{anexoArquivoBean.fileUploadAction}" auto="true" />

No seu web.xml, o parametro javax.faces.STATE_SAVING_METHOD está para client? Se estiver, tente como server.

<context-param>
  <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
  <param-value>server</param-value>
</context-param>
