Topic: remote method invocation

Part 1.

Install the Apache web server on your machine. See http://httpd.apache.org/

Part 2.

Follow the Oracle tutorial on Java RMI: http://docs.oracle.com/javase/tutorial/rmi/overview.html

Copy the code, and run everything on your machine.

Part 3-a.

Write your own implementation of an RMI client and server. The exposed method takes only primitive data as input, and returns primitive data. An example could be the following:

A server provides a remote method to add two numbers, and returns the result.

A client asks the user for two numbers, sends the request to the server, gets the response, prints the two numbers and the response.

Personalize the above problem (Examples: change currency, calculate number of seconds mond two dates (represented as integers!), evaluate square root...)
If possible, try to run the client and the server on two different machines using a virtualization program.

Part 3-b.

A “Notebook” is custom class (i.e. a class that you build), which is able to keep a set of strings (an arbitrary number of strings), and to print them.

A server shows a remote method “sign” with a parameter of type Notebook. The method “sign” adds a signature to the Notebook. There will be two instances of the server (they may run on the same machine).

A client will create a Notebook, and ask the two servers to sign it. At the end the client prints the content of the Notebook.

If possible, try to use two different (virtual) machines: one for the client and one for the two the servers.
