java - spring bean properties with singleton -

-

need clarification on spring singleton .i have 3 objects ,these readonly never changed values.

i planning create these objects singleton bean properties.

my question: when spring creates these objects,everytime create new object when bean calls or once in life time call , create objects?. possible threading issues if any?

it depends on spring do. spring has inversion of control container manages instances of objects. depending on scope give objects, make them singletons or not.

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
