Hi David,
this is just a screen class which extends RawScreen as in my example.
Since I am taking the HttpOutputStream there and wirte to it and close
it, there is no template which has to be parsed...
I have commented my source below:
/* Extend RawScreen, so we can write directly to the Servlets
OutputStream */
public class ArchiveImage extends RawScreen
{
/* return the Content type of this page so the browser knows what is
coming */
protected String getContentType(RunData data)
{
return "image/jpeg";
}
protected void doOutput(RunData data) throws Exception
{
/*
Get all the necessary Data to display the screen.
The Path to the Image (which is stored on the filesystem
rather than the db) is stored inside the db
*/
AccountingArchive record =
AccountingArchivePeer.retrieveByPK(data.getParameters().getInt("id"));
/* Now that we have the record open the image and get an
inputstream for it */
FileInputStream in = new FileInputStream(Archiver.IMAGE_PATH +
"/" + record.getImagePath());
/* Create a new ByteBuffer for Reading the Content */
byte[] b = new byte[2048];
/* Get The OutputStream for this screen */
OutputStream out = data.getResponse().getOutputStream();
/* While we can read Data into the Buffer print it on the
OutputStream of the Screen */
while (in.read(b) > -1)
{
out.write(b);
}
/* Finally Flush the Stream */
out.flush();
}
}
