> Hi,
> I was trying to launch an apex app from a user defined path by specifying dt.attr.APPLICATION_PATH = <some_user_path>
> No other user has access to the above path.
> The application launch works fine but I am not able to get the application info from a webservice since the retrieveWebServicesInfo in StramAgent is failing on an AccessControlException for the permissions.json file which is not in use.
> Since this file is not a mandatory file, we can catch an IOException here which would encompass the existing FileNotFoundException & AccessControlException and let the call return the StramWebServicesInfo object.
> Proposed change :
> try (FSDataInputStream is = fileSystem.open(new Path(appPath, "permissions.json"))) {
>         permissionsInfo = new JSONObject(IOUtils.toString(is));
> } catch (IOException ex) {
>         // ignore if file is not found
>         LOG.info("Exception in accessing the permissions file", ex);
> }
> [~PramodSSImmaneni] - does this approach look fine ?
> Thanks,
> Dev
