PDF Streamed To Client 

I'm wondering if anyone has any tips on how to render a pdf with struts.  I want to mask the name of the pdf and just stream it to client.

Thanks

Or use the new DownloadAction - it is in the Struts 1.2.6 beta version,

Brian:

This is pretty simple.  Just get the output stream from the response
object and stream the file down.  Return null from the Action's
execute method:

    private void returnFile(File f, OutputStream out) throws IOException {
        FileInputStream fis = null;
        try {
            fis = new FileInputStream(f);
            byte[] buf = new byte[8 * 1024];
            int bytesRead;
            while ((bytesRead = fis.read(buf)) != -1) {
                out.write(buf, 0, bytesRead);
            }
        } catch (IOException ioe) {
            log.error(ioe, ioe);
        } finally {
            if (fis != null)
                fis.close();
        }
    }

I have successfully used the following technique for file download via an
action:

Set the mimetype in the web.xml

Do nothing action always returns 'success' points to tiles def for file to
be downloaded

action-map:
<action path="/fileDownloadAction"
        type="com.foo.action.SuccessAction"
        name="someInitiatingForm" validate="false" scope="request">
  <forward name="success" path="file.download.entry" />
</action>

tiles-def:
<definition name="file.download.entry" path="path/to/my/file/foo.pdf">
</definition>

I'm wondering if anyone has any tips on how to render a pdf with struts.  I
want to mask the name of the pdf and just stream it to client.
