The projected J2EE- application was built on a custom J2EE framework which uses JSP/Servlets for presentation logic and a set of classes for DB layer and business logic, which are tied together by one single request processor. That made it possible to achieve good system scalability with performance being not affected seriously. JavaMail was used for all activities related to the e-mailing such as connection to remote POP3/SMTP servers, e-mails fetching and some others.

The application includes the following functional modules:

• Extended customer contact management;
• Time Management;
• Built-in web-based e-mail messaging service;
• Information and tasks sharing possibilities.

Technologies used: Jakarta Tomcat 4 Server, MySQL, MS Project 2002, RUP, J2EE, JavaMail, JavaScript, DHTML.

Efforts: 6 man-months.
