Sample Address Book

Here is a sample address book application based on 3-tier architecture and with various frameworks and toolkits such as :

Presentation layer

• GWT
• EXT GXT

Logic layer

• Spring
• Hibernate

Database layer

• HSQLDB (or MySQL)

Source code as eclipse project is available here . Please note, in order to run project in eclipse, a maven 2 plugin must be installed. I suggest m2eclipse (http://m2eclipse.codehaus.org/).

Requirements for the address books are as follows:

• A simple address book with three separate pages.
  
• The first page should allow the user to input up to 50 names and phone numbers at a time. The user can input between one and fifty name/numbers at a time.Each name must be unique and have only one phone number.Both the name and the phone number must not be blank.The names and phone numbers should be stored in memory. Phone numbers should be validated to contain only numbers, with an optional + prefix and possibly one pair of brackets with at least one number in them. The phone number must start either with a + or a 0 - if it starts with a +, it cannot be followed by a 0.


• The second page should list all stored numbers and names, sorted alphabetically.


• The third page should allow a user to search the address book by phone number (exact number, not substrings) and also by full name or part of a name (case insensitive). It should display all matching names and related phone numbers for the search criteria.
