Hi,

I'm having problems with downloading files from my application (in
Websphere 5). I have written an action in struts that does the
following thing:

{ String filename =
request.getParameter(VisualConstants.RKEY_SELECTED_DOCUMENT_NAME);
String path =
request.getParameter(VisualConstants.RKEY_SELECTED_DOCUMENT_PATH); File
file = new File(DocumentUtil.getAbsoluteDocumentPath(path));
response.setContentType("application/unknown");
response.setHeader("Content-Disposition", "attachment; filename=\"" +
filename + "\""); long fileLength = file.length();
response.setHeader("Content-Length", new Long(fileLength).toString());
BufferedInputStream bis = new BufferedInputStream(new
FileInputStream(file)); ServletOutputStream stream =
response.getOutputStream(); int data; while ((data = bis.read()) != -1)
{ stream.write(data); } bis.close(); stream.flush(); stream.close();
return mapping.findForward("success"); }

The download works, but I get the download window two times. In my
logging I can see the following thing:

E SRVE0026E: [Servlet Error]-[JSP 1.2 Processor]:

try returning null instead of mapping.findForward("success");

this works.
