Question

I have issue with primefaces 5.0 component p:fileDownload , I have following bean store DefaultStreamedContent , and I get the value stored to download it simply :
Bean :
public class EBMail implements Serializable {
private DefaultStreamedContent attachment;
// # here setter and getter too .
}
and from XHTML file :
<p:commandLink ajax="false" value="Download Attachment" rendered="#{mbMail.attachment != null}">
<p:fileDownload value="#{mbMail.attachment}" />
</p:commandLink>
I get mail attachment file for first time, in 2nd time I get the following exception :

I'm running on JFS 2.2.7 , Primefaces 5.0 , I upload file into bean my issue when I download it for 2nd time, even for another object 'mail' .
Any solution, I looked after many solutions around nothing helped me or I've already tested it.

Answer 1

I solved issue finally, I make new class store my data, and action that prepare stream to download from my class object, and when download file I read bytes from my class bytes, like the following:
Class:
public class Attachment implements Serializable {
private String name;
private String type;
private String encoding;
private byte[] data;
// ... Setters and getters ...
public Attachment () {
this.encoding = "UTF-8";
}
}
Bean:
public class MailBean implements Serializable {
// alot of properties
private Attachment attachment;
// setters and getters
}
Managed Bean :
public class MailManagedBean implements Serializable {
private DefaultStreamedContent attachmentToDownload;
private MailBean mail;
// # here setter and getter too .
public void prepare() {
InputStream stream = new ByteArrayInputStream(mail.getAttachment.getData());
attachmentToDownload = new DefaultStreamedContent(stream, mail.getAttachment.getType(), mail.getAttachment.getName(), mail.getAttachment.getEncoding());
}
}
In XHTML file (I added action) :
<p:commandLink ajax="false" value="Download Attachment"
rendered="#{mbMail.mail.attachment != null}" action="#{mbMail.prepare()}">
<p:fileDownload value="#{mbMail.attachmentToDownload}" />
</p:commandLink>

Answer 2

public StreamedContent getExportFile() {
Field field = exportFile.getStream().getClass().getDeclaredField("path");
field.setAccessible(true);
String path = (String)field.get(exportFile.getStream());
InputStream tempStream = new FileInputStream(path);
exportFile = new DefaultStreamedContent(tempStream,exportFile.getContentType(), exportFile.getName());
return exportFile;
}
