where to store uploaded images - in the tomcat application or on the server?

What do you suggest for location of images that the user uploads 开发者_JS百科to my application?

in my server application (like WebContent->images) or in system location?

Store it outside the Tomcat installation. That makes updates of both Tomcat and your application a lot easier.

You could also think about storing the images as BLOB in a database.

You can map an external directory outside Tomcat within server.xml to store the images.

Use the <Context docBase="/some_path_on_your_machine"> tag for this.

If you use a database, it is recommended to store the path to the image in the database, and the actual image on filesystem.
