Access denied to resource file from java servlet

Question

I am trying to access a resource file from a servlet but getting HTTP Error 500 - access denied:

File file = new File("//warChildFolder//myFile.txt");
InputStream is = new FileInputStream(file); // <--error on this line

I am on google-app-engine.

Any help appreciated!

Answer 1

Google App Engine docs talk about "white listing" a file. Is that in play here?

I also wonder about this:

File file = new File("//warChildFolder//myFile.txt");

Doesn't the leading slash make this an absolute path?

I'd try it like this:

File file = new File("WEB-INF/warChildFolder/myFile.txt");

Make the path relative to the WAR root and be explicit about WEB-INF.
