-Offers a service where users can make selection from several music channels.+Offer a service where users can play videos from different channels through a common portal. Available channels are shown for users in a list. Selecting a channel from list shows a list of videos available from that channel. Selecting an item from video list will show it with an embedded player.
  
-====== Services====== 
-  * Offer list of available music channel through a common portal 
-    *   
-  * Users can browse different jukebox play lists 
-    * Jukeboxes offer information about available music 
-    * Users can search for music 
-  * Users can send play requests to jukebox of their choice 
-    * Requests are send to a jukebox which handles requests as it sees fit(?) 
  
-(focus on core idea functionality)+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.

 +==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.
