I currently have a java library in subversion under package: com.company.product.foo.* Unfortunately, I have to refactor this into: com.othercompany.bar.* That'd be fine as a one-shot. But this has to be performed only on a specific branch. The problem is then to merge changes from trunk to the branch with totally different names. ...

Given a URL, how can you tell if the referenced file is and html file? Obviously, its an html file if it ends in .html or /, but then there are .jsp files, too, so I'm wondering what other extensions may be out there for html.

Normally with Java Swing you can set the background color of a button with: myJButton.setBackground(Color.RED); which would cause the button to be red. But on the Mac OS, this method seems to be ignored. The button just stays the default color. How can the color of a JButton be set on the Mac OS? ...

Something like: void foo() { a += "xyx"; bar(); } void bar() { a += "abc"; } For unit testing purposes, I want to test foo and bar separately. Is there any way to prevent bar from being run when I call foo() or to replace...

The tutorials seem to show you how to do something with their package, but not why you would want to use their package (or in which cases ...
