SanEd consulting

Company profile

SanEd consulting is an IT training company which initiated its services in 2005 primarily as Sun Microsystem's authorised training provider. Our training portfolio was Solaris and Java focused. Later on we upgraded our portfolio and included authorisations from Veritas / Symantec and Oracle after aquisition of Sun. 

As the global IT market is rapidly changing and developing we must have accepted its needs and trends. Thus, beginning of 2014 we decided to "refurbish" our services and included new, young and perspective partners and together prepared number of interesting trainings you can find in our catalogue.

We are looking forward to successful cooperation with you.

This four-day course introduces experienced Java programmers to the Java Micro Edition, or Java ME, and develops skills in Java programming for wireless devices via the Mobile Information Device Profile, or MIDP. The course begins with a top-down tour of the ME architecture, focusing on wireless programming via the Connected, Limited Device Configuration, or CLDC, and the MIDP. Students learn the simple Core API of the CLDC -- primarily by contrast to the Java Standard Edition Core API - and then move into the individual packages of the MIDP.

We then study MIDP development in detail, working through several chapters on user interfaces and event handling, to local record storage and network connectivity, and on to threads and timers. The course concludes with chapters on advanced topics including memory management, best practices, and "over the air provisioning," which is a standard deployment model for MIDP applications to wireless devices via HTTP, including a security model using digital signatures.

This course is intended for experienced Java programmers: Course "Java Programming" would be a good starting point for those without significant Java experience.


Skills gained

  • Understand the Java Micro Edition architecture, and the stacking of virtual machine, configuration, and profile to address different types of micro devices.
  • Understand the mission of the Mobile Information Device Profile, and see how programming for mobile devices is fundamentally different from Java SE programming.
  • Build a simple, functioning "MIDlet."
  • Understand the framework for packaging and deploying MIDlets to devices.
  • Build user interfaces for mobile devices, including text presentation, graphics, keypad and pointer event handling, and multi-screen navigation.
  • Save and re-load information from one MIDlet run to the next using the MIDP Record Management System.
  • Make HTTP network connections from the mobile device.
  • Use multiple threads and MIDP timers effectively.
  • Manage memory usage conservatively in MIDP applications.
  • Deploy completed MIDlet suites to mobile devices over the air.
