Web Services and Mobile Devices

This session will examine the opportunities that exist for enabling mobile devices to invoke web services. In addition, this session will discuss the tools and technologies that make this possible. Because of the constraints of a mobile device, there are various considerations that must be made in order to effectively utilize web services on mobile devices. These issues are examined, and specific programming recommendations made. This session will also examine the various wireless networking topologies and considerations for each when providing a mobile web services solution.

Advanced Java Multi-threading Techniques

In this session, Peter will demonstrate various programming techniques for properly behaved multi-threaded code. In addition, he will explore multi-threading issues and strategies including: atomicity, the proper use of volatile and synchronized to guarantee thread safety, issues with the memory model, double-checked locking, and specific notification. Sample source code used in this session is provided.
