get file

[judovana]

hi.
I have an been under JSF (now RF) which redirect me

 FacesContext facesContext = FacesContext.getCurrentInstance();
 ExternalContext ec = facesContext.getExternalContext();
 ec.dispatch("../download");

to servlet, which returned me FILE by this code:

 byte[] bytes = str.getBytes("UTF-8");
 InputStream input = new ByteArrayInputStream(bytes);

int length = 0;
ServletOutputStream op = response.getOutputStream();
ServletContext context = getServletConfig().getServletContext();
String mimetype = context.getMimeType( "pokus.xml" );

response.setContentType( (mimetype != null) ? mimetype : "application/octet-stream" );
response.setContentLength( (int)bytes.length );
response.setHeader( "Content-Disposition", "attachment; filename=\"" + original_filename + "\"" );


 byte[] bbuf = new byte[bytes.length]; //here is my generated xml

DataInputStream in = new DataInputStream(input);

while ((in != null) && ((length = in.read(bbuf)) != -1))
{op.write(bbuf,0,length);}

in.close();
op.flush();
op.close();

But when I swapped poor JSF for RF i stoped working with error message Ajax4JSF own this stream (sorry not copy paste, i do not have this message anymore). So now i cannot return the file.
I swapped this code to save those bytes to tmp file and redirect to this file. But it is noto so user friendlyas first solution.
On RF pages is eritten that existing JSF project can use them without loosing it's functionality;) Have RF any similar solution to return files instead of page?

Hello,

1. It's not a redirect, but forward. How do you call this bean method: by method or by some other means?

2. I do not see FacesContext#responseComplete() call in the code posted, do you have it somewhere?

Got typo in my post, fixed:

1)In jsf-page i have button in the form and sending this form.

 <h:commandButton id="downlaodTrip" action="#{DownlaodBean.register_action}" value="#{msgs.form_download_trip}" />

then in bean

 @TransactionAttribute(javax.ejb.TransactionAttributeType.REQUIRES_NEW)
 public String register_action() {
 try {

 FacesContext facesContext = FacesContext.getCurrentInstance();
 ExternalContext ec = facesContext.getExternalContext();
....

so by action.

but..:)
2)FacesContext#responseComplete() i have NOWHERE. It should be somewhere O:-)

Please try to add FacesContext#responseComplete() just before dispatching to "../download" context.
