Comecei a desenvolver importação de arquivo seguindo esse tutorial:
http://quebrandoparadigmas.com/?p=168
Abaixo as classes que estou utilizando:
Classe FileUploadController
[code]package bean;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import javax.faces.bean.SessionScoped;
import model.Estrato;
import model.HibernateUtil;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.primefaces.event.FileUploadEvent;
import org.primefaces.model.DefaultStreamedContent;
import org.primefaces.model.StreamedContent;
@ManagedBean
@SessionScoped
public class FileUploadController {
private String nomeArquivoSelecionado;
private StreamedContent imagem;
public StreamedContent getImagem() {
return imagem;
}
public void setImagem(StreamedContent imagem) {
this.imagem = imagem;
}
public String getNomeArquivoSelecionado() {
return nomeArquivoSelecionado;
}
public void setNomeArquivoSelecionado(String nomeArquivoSelecionado) {
this.nomeArquivoSelecionado = nomeArquivoSelecionado;
}
public void fileUploadAction(FileUploadEvent event) {
try {
setNomeArquivoSelecionado(event.getFile().getFileName());
imagem = new DefaultStreamedContent(event.getFile().getInputstream());
} catch (IOException ex) {
Logger.getLogger(FileUploadController.class.getName()).log(Level.SEVERE, null, ex);
}
}
} [/code]
Pagina index.xhtml (Coloquei apenas a parte que adicionei do componente de importação para simplificar):
<p:layoutUnit position="center">
<h:form>
<p:fileUpload auto="false" label="Selecionar..." allowTypes="*.jpg;*.png;*.gif;" multiple="false" description="Imagem" update="idimagem" fileUploadListener="#{fileUploadController.fileUploadAction}" /> <br/>
<p:graphicImage id="idimagem" value="#{FileUploadController.imagem}" />
</h:form>
