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
