RE: [OT] Storing files outside of the web context

[Jesse Alexander \(KSFD 121\)]

You could use a web.xml centext-param to pass the absolute path to the servlet.

 

In my experience the getRealPath()-method more often than not returns null. If you want to server resources from

a jar then use weblets. If you want to serve them from the filesystem use an absolute path configured via a

system-setting of a context-param.

Absolutely.  You could hard code a file path from inside a backing bean and save the file anywhere on your system if you wanted.

Here's some quick code I stole from one of my servlets that reads a file from anywhere (just define your own filename) and sends it to the response:

ServletContext sc = getServletContext();
String filename = sc.getRealPath("/images/bcg.gif");

// Get the MIME type of the image
String mimeType = sc.getMimeType(filename);
if (mimeType == null) {
        mimeType = "text/plain";
}

// Set content type
response.setContentType(mimeType);

// Set content size
File file = new File(filename);
response.setContentLength((int) file.length());
               
//Set headers
response.setHeader("Content-disposition", "attachment; filename=" + filename);
response.setHeader("Cache-Control", "max-age=600");

// Open the file and output streams
FileInputStream in = new FileInputStream(file);
OutputStream out = response.getOutputStream();

// Copy the contents of the file to the output stream
byte[] buf = new byte[1024];
int count = 0;
while ((count = in.read(buf)) >= 0) {
        out.write(buf, 0, count);
}
in.close();
out.close();

I have a jsf app that includes many .pdf files of contracts.  I've just
been putting them all in the war before deploying to the production
server.  There must be a better way to do this.  Is it possible to store
these files elsewhere on the web server, outside of the context, and
still be able to link to them?

Thanks
