[java] How to load a resource from WEB-INF directory of a web archive

I have a web archive with a file placed in the WEB-INF directory.

How do I load that file in a java class?

I know I can put it in the classes directory and load it from there. It would just be put it in WEB-INF.

Here is how it works for me with no Servlet use.

Let's say I am trying to access web.xml in project/WebContent/WEB-INF/web.xml

1. In project property Source-tab add source folder by pointing to the parent container for WEB-INF folder (in my case WebContent )

2. Now let's use class loader:

   InputStream inStream = class.getClass().getClassLoader().getResourceAsStream("Web-INF/web.xml")
   

The problem I had accessing the sqlite db file I created in my java (jersey) server had solely to due with path. Some of the docs say the jdbc connect url should look like "jdbc:sqlite://path-to-file/sample.db". I thought the double-slash was part of a htt protocol-style path and would map properly when deployed, but in actuality, it's an absolute or relative path. So, when I placed the file at the root of the WebContent folder (tomcat project), a uri like this worked "jdbc:sqlite:sample.db".

The one thing that was throwing me was that when I was stepping through the debugger, I received a message that said "opening db: ... permission denied". I thought it was a matter of file system permissions or perhaps sql user permissions. After finding out that SQLite doesn't have the concept of roles/permissions like MySQL, etc, I did eventually change the file permissions before I came to what I believe was the correct solution, but I think it was just a bad message (i.e. permission denied, instead of File not found).

Hope this helps someone.
