 The initial idea of remote jukebox service had to be scrapped as there was no feasible way to create a jukebox service that could be used remotely during the course. The initial idea of remote jukebox service had to be scrapped as there was no feasible way to create a jukebox service that could be used remotely during the course.

 +====Implementation====
 +Implementation consists of four classes:
 +  * //TestprojectApplication// that contains the application start code and is initially created by **Vaadin** tools
 +  * //ChannelController// class that controls the loading of content for channel and video list containers.
 +  * //ChannelView// class consists of //Embedded// video player and //Table// view for available channels. Implements //PlaylistChangeListener// from //ChannelController// to change playing video according to selection.
 +  * //PlaylistView// class consists of //Table// that shows available list of videos for selected channel. Implements //ChannelChangeListener// from //ChannelController// to change playlist according to selected channel.
 +
 +
 +Current implementation uses prelisted content instead of dynamic content loaded from video sites. This could possibly be improved as an automated listing through a channel, for example, loaded from youtube.com.

 +====Vaadin review====
 +==Component summary==
 +  * VerticalLayout
 +  * Label
 +  * SplitPanel
 +  * GridLayout
 +  * Embedded
 +  * Table
 +
 +Main window is VerticalLayout that contains a caption Label and vertical SplitPanel. Top part of SplitPanel contains a GridLayout where Embedded component  (flash video player) is on the left side and channel list Table is on right side. Bottom part of SplitPanel holds VerticalLayout holding a Table where available video list is loaded when an item is selected.
 +
 +==Impressive!==
 +Lots of different components.
 +
 +==Problems==
 +Positioning items on the screen is somewhat hard at times. Especially relative width/height requiring some absolute width/height from higher level element seemed somewhat confusing.

 +====Acknowledgments=====
 +Special thanks for the group 6 for helping us with jukebox software installations and deployment even though it didn't realize as a software during this course.
