I have a Java excersize with two parts. I want the first part for $24, and the second (the small and easier one) for $6. So $30 for both of them. I have zero time and i need it in 48 hours from now. Max 56 hours only if you have a serious problem..
You should have such experience as the requirements stated. (Java, RMI, Remote Sensing or such) and to be online some hours per day so we can communicate about your progress
Thank you a lot in advance,
1. A camera with built-in motion detection sensor "watches"' a space controlled by an RMI server. Whenever the sensor detects motion, the server generates a motion event, giving it a time stamp and sends it to all RMI clients that have expressed interest in such events. Besides the server sends motion event to each client and an image file that contains a snapshot of motion detected. The client application implements a simple GUI which records the events received and displays the last image taken (see. Figure 1 attached). The server should serve multiple clients simultaneously.
The server simulates the operation of the motion sensor agent sequentially traffic events in a random, with a time-distance of a few secs (e.g., up to 2-5 ses). To obtain a rotation of the image between successive events that take your customers, two png files are attached, that you should use as the snapsot camera that ships upon detection of motion.
The nature of the application is such that the client should not do polling to the server for VISIBLE events, but the server should notify clients via callback methods. This means that every lient should be able to export some of its methods that can be called remotely by the server. Each client respectively registers in the service the server offers, and when the server terminates, client stops sending of notifications.
Implement a distributed application using Java RMI. The application will be implemented in NetBeans and should be able to run through the tool environment without the need for external intervention (eg external execution of registry). If you need to specify a path to an external file, it should be relative and not absolute so that no problems arise during the deployment of the application.
As long as there is no dynamic load of classes from the network, you can not implement a security manager or security policy for this application.
Finally, include, if necessary, special instructions for running the application.
2. Use Java sockets to develop an application (client / server type) that will provide as a service, the current date and time of the server machine. Before you send this information to the server wait a random time between 0 and 3 sec. The client application (timeClient) will print the date and time received. The service server (timeServer) will be served on port 44 while the server address (IP address or hostname) is 127.0.0.1 or localhost How you ensured that the service will be served simultaneously to multiple clients?
For the implementation should use the NetBeans environment.
