Netbeans 6.0 gives really nice support for developing Java Micro Edition applications. It provides some useful classes which are not part of standard JME profiles.
One of them is class: org.netbeans.microedition.lcdui.pda.FileBrowser.
It provides file browser for mobile phone implementing JSR-75. It looks fine but there is a bug in it. Method getSelectedFileURL() returns incorrect value, e.g.: file:///E:/myfolder//myfile.mp3 instead of file:///E:/myfolder/myfile.mp3
Removing manually last extra slash fixes the problem.
