This course enables participants to acquire the skills needed to develop applications in a distributed environment. It shows how to integrate potentially heterogeneous applications to make them interoperable by using web services suited to the Java language and the Java EE platform. Numerous hands-on workshops allow participants to develop, publish, and use their first web services while working with the appropriate standards.
Objectives
At the end of the course, the participant will know how to develop and integrate Java web services in a distributed environment. They will master the essential standards for publishing, consuming, and making web services interact.
