zipped jar file

Find out:
- What is their name?
- Where do they inherit from?

Only for the Mistery class:
- which methods are exposed by the class (ignore the inherited ones)?
- what is every public method doing? Run them in order to be able to guess what is their functionality and the meaning of their params.

Deliver a report and the source code.

Assignment n.5

Marco Ronchetti marco.ronchetti@unitn.it — Tue, 16 Oct 2018 10:52:00 +0200

Delivery deadline: midnight of Sunday, Oct.21

"Document” is custom class (i.e. a class that you build), which contains a text (implemented as an ordered collection of strings). It has methods "addString" (which appenda a String at the end of the Document) and a method "toString" (which overrides the toString method of the Object class), useful to print out the whole Document.

A server shows a remote method “validate” with a parameter of type Document. The method adds the string "Validated on "+date in the Document.

A client will create a Document, and ask the server to add the timestamp. At the end the client prints the content of the Document, which of course will have to contain the validation.

NOTE: Before embarking in the project execution, I strongly suggest to follow the Oracle tutorial on Java RMI: http://docs.oracle.com/javase/tutorial/rmi/overview.html

Also the following tutorial may be useful: https://www.tutorialspoint.com/java_rmi/index.htm.

Assignment n.6

Marco Ronchetti marco.ronchetti@unitn.it — Tue, 30 Oct 2018 10:29:00 +0100

Install Hibernate.
Create an application (you choose the applictive domain) which creates objects of two classes with one relation among them (e.g.: student and exam, customer and order...). A number oof these object have to be saved on a Database.

Another application runs a query to find and print saved object (e.g. all exams given by a student after a given date).

Implement it using only Java SE and Hibernate (not EJB).

Deliver a report and the source code (including configuration files).
