• If I'm running my App Engine app on localhost, will I not see a value for X-AppEngine-Country?

  - by Bartholomew

  According to the Release Notes: All user request have an X-AppEngine-Country header which contains the ISO-3166-1 alpha-2 country code for the user, based on the IP address of the client request. My app is running on localhost with the 1.5.1 Java release which contains the X-AppEngine-Country header but I don't seem to be receiving any value for this header in my requests. Do I have to deploy the app to a production instance to test this feature?

• Can I move another program's window to the front of focus?

  - by TwentyMiles

  I am interacting with a third party application using it's API, and would like to move it to the front of focus (so that it is on top of all other open windows) when a user performs a certain action. While I can move my application up and down in the hierarchy pretty easily, there doesn't appear to be a way to interact with other windows. Is it possible to move another program's window to front with Java?

• Can I Define Exceptions to Eclipse cleanup rules?

  - by Henrik Paul

  Most often the cleanup rules (Preferences Java Code Style Clean Up) in Eclipse work perfectly and create nice-looking code. But sometimes, especially with comments and concatenated string snippets (like inline SQL queries), the cleanup just messes things up, and destroys my formatting. Is there a way to say to Eclipse "Don't touch this block of text! I have formatted it just the way I like, and you would make it just less readable"?

• final fields and thread-safety

  - by pcjuzer

  Should it be all fields, including super-fields, of a purposively immutable java class 'final' in order to be thread-safe or is it enough to have no modifier methods? Suppose I have a POJO with non-final fields where all fields are type of some immutable class. This POJO has getters-setters, and a constructor wich sets some initial value. If I extend this POJO with knocking out modifier methods, thus making it immutable, will extension class be thread-safe?

  I'm having a session object that does NOT implement the java.lang.Serializable. (its a legacy application, and now I can't go and change the code) Is there any way where I can store the session object some where and later GET BACK THE SAME STATE in a STANDALONE application. One thought is to use RMI. Is there any better way of achieving this. Thank you :)
