In today s world, the demand for video in the Internet has gained high popularity. One of the best and optimal ways to provide the video contents on demand to users is through web services. This research aims to develop a generalized web service model for providing video on demand. To fetch the video file requested by the user, JAX-RPC is been used, which is more flexible and loosely coupled. The implementation of the developed web service depicts the methodology for providing video contents on demand in real time. The video distributors can adopt this model, as it ensures smooth and jitter-free videos, thereby both the users and the distributors will be benefitted. The performance measure, Round Trip Time (RTT) is estimated for the developed JAX-RPC video on demand model by requesting the video files of various sizes in both local invocation and remote invocation. The result shows that the developed model solves the connectivity issues and interoperability which was a major constraint with the rmi model. The performance was better for smaller video files when compared with the larger files and there was very little variation obtained between the local and remote invocation.
