Scala/Lift - Cannot access image uploaded until jetty is restart

I created a file upload form, the form will take an image fi开发者_如何转开发le from user then save it in the webapp/images/ directory.

The problem is I cannot access the image uploaded by user until jetty is restarted.

Is there anything I should add to the code? Do I need to add anything on the sitemap?

Thanks for the help
