Dear Experts,
I have this action class to perform file downloading function, however, it
doesn't export excel file correctly, it give me a 'actionClassName.zip' file
instead of the excel file, but other format files like pdf file, jpg file
and text file are fine though, can't figure it out why
My action class code:
public class DownloadDocumentAction extends Action {
private static Log log =
LogFactory.getLog(DownloadDocumentAction.class);
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
try
{
String token = OpenkmUtils.getToken();
byte[] localFile = OpenkmUtils.getFile(token, okmPath);
ServletOutputStream out = response.getOutputStream();
InputStream in = new ByteArrayInputStream(localFile);
byte[] buffer = new byte[1024];
int length = -1;
while((length = in.read(buffer)) != -1) {
out.write(buffer, 0, length);
}
in.close();
out.flush();
out.close();
}
catch (java.io.IOException ex)
{
log.error(ex.getMessage());
}
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition","attachment;filename=\"" +
fileName+"\"");
return null;
}
}
