Java Backend DevelopmentLaajuus (5 cr)

Objective

Purpose of the course

Are you interested in the Java backend technologies favoured by large companies and organisations? JakartaEE (JEE) is a very important technology especially for the development of enterprise-level backend applications. There is a constant shortage of skilled developers on the labour market. JEE is used in information systems of e.g. banks, insurance companies, KELA and many ERP systems. This course provides the basic skills to start working as a Java backend application developer.

Course competences

- Application development: knows the technologies used in application development and recognizes the significance of different technologies and their relationships.
- Application development: Is able to program and develop secure applications.
- Software Engineering: Is able to define, plan, test and/or implement software products.
- Learning to learn: Is able to acquire, critically assess and appropriately apply the national and international knowledge base and practices of their field.

Learning outcomes

You will be able to implement backend applications in Java. You will know the basic functionality of the JEE application server and be able to use the application framework to develop a Java backend application.

Content

The course teaches how to develop Java backend applications. Content includes development environment setup, Maven project management, Java Persistence API (JPA), Web Services: JAX-WS and JAX-RS, Spring Framework and the Liferay portal platform. The course provides the basic skills needed to become a Java backend developer.
