BBScreenShooter and BBScreenStream require the file javaloader.exe from RIM in order to function. It needs either to be in the same folder as the tool or a pop-up window will ask for the path to javaloader.exe.
You can download javaloader.exe as part of the BlackBerry JDE Components package 4.x from RIM. (BlackBerry)

The tools themselves can now be downloaded here:

BBScreenShooter:
oppitronic.de

BBScreenStream:
oppitronic.de
