Question

I have a page on my GWT & App Engine application that is basically a table of files that the user has uploaded.

Here is the last part of the doGet function of BlobServiceImpl, that serves the blobs when the user requests:

    // got the entity already

    filename = (String) entity.getProperty("filename");

    resp.addHeader("Content-Disposition", "filename=" + filename);

    blobstoreService.serve(blobKey, resp);

The code above gets the filename from the entity metadata, set the filename in the HttpServletResponse and then serve the actual blob.

The problem I am having is that for files with a space in the filename, Firefox sets the filename to the first word only – everything after the space is excluded. This is quite annoying as a file called “My Amazing File.xls” will be saved as “My”.

Something to do with the character encoding perhaps? Strange that it works fine in other browsers.

Thanks for helping 🙂

Answer 1

As Amy has said, this is a Firefox problem, nothing to do with App Engine.

Changing this:

resp.addHeader("Content-Disposition", "filename=" + filename);

To this:

resp.addHeader("Content-Disposition", "filename=\"" + filename + "\"");

fixed my problem.

Happy coding!
