developing servler using java servlets

dear all,

Im now developing a server for a 3G service.

It has two major functions:

1) Link the traffic users to the database to let them choose which road they want to choose in order to reach their destiny.

2) Stream the video from the camera by the road to let them have a look with the traffic condition of the road which they have selected.

Currently i am developing the database of my system.

question:

1) Is anyone has some examples in building up the connection between the servlet and Database using JDBC?

2) What kind of method should i use in servlet in order to stream the video from a camera to the user?

Thanks!!
