[opencms-dev] Download a file from administration point

[Paul-Inge Flakstad]

Hi Àlex,

Silly question perhaps, but since it's not completely apparent from the code you provided: Are you missing something like

resp.getWriter().write(buffer.toString());

?

Just returning won't do much (and that fits with what you're experiencing).

Cheers,
Paul

Subject: [opencms-dev] Download a file from administration point

Hi,

I'm trying to create a dialog to download a file for an administration point (à la CmsUsersCsvDownloadDialog) to download an html file with a certain content. The class extends CmsWidgetDialog

I've generated a method downloadFile() that redirects a StringBuffer to the response, that makes like this:

...
             StringBuffer buffer = new StringBuffer();

             HttpServletResponse resp = CmsFlexController.getController(getJsp().getRequest()).getTopResponse();

             resp.setContentType("text/html");
             buffer.append(exportFileContent);
             resp.setHeader("Content-Disposition", new StringBuffer("attachment; filename=\"").append(filename).append("\"").toString());
             resp.setContentLength(buffer.length());

             LOG.info("End actionCommit() method. Buffer content: " + buffer.toString());

             return buffer.toString();

The buffer.toString() method returns, of course, the correct value. That is, the content of the StringBuffer. However, I'm getting a blank .html file with no content inside. What could have possibly gone wrong?

Thanks in advance,
