simoichigo · 30 Aug 2013, 17:31

code of .xhtml :

<p:commandButton value="Telecharger" icon="ui-icon-arrowthick-1-s">
	<p:fileDownload value="#{downloadBean.file}" />
</p:commandButton>

code of .java :

Code: Select all

package ma.corporate.bean;

import java.io.InputStream;
import java.util.List;
import javax.faces.context.FacesContext;  
import javax.servlet.ServletContext;
import ma.corporate.facade.CvFacade;
import ma.corporate.model.Cv;

import org.primefaces.model.*;

public class DownloadBean {
	private StreamedContent file;
	//private List<Cv> cvs = new CvFacade().ListeCvs();
	//private static int cpt=0; 
	public DownloadBean() {
		//System.out.println(cpt);
		InputStream stream = ((ServletContext)FacesContext.getCurrentInstance().getExternalContext().getContext()).getResourceAsStream("/VAR/indexed_primefaces3.pdf");// Stream("yourfile.pdf");+cvs.get(cpt).getUploadPath()
		file = new DefaultStreamedContent(stream, "application/pdf",
				"machakile.pdf");//cv.le vrai nom lol !!!
		//cpt++;
	}
	public StreamedContent getFile() {
		return file;
	}

   <p:fileDownload value="#{downloadBean.file}" />
</p:commandButton>
