Description of the current architecture developed with JXTA

In this chapter we discuss one prototype. We plan to update this prototype that will be totally merged in DIET and able to process all requests supported by DIET. The DIET architecture is shown Figure 7.1. We can consider that the elements allowing its use are divided in two parts:

• a JXTA part that includes client, MA and SeD. These components are written in java to be able to communicate together using JXTA.

• a part of integration of the JXTA part in DIET: java (JXTA) and C++ (DIET) must cooperate. The technology used to allow this integration is JNI [12] that allows java to call functions written in C++. JNI is located in the MA and the SeD: The MA has to launch and communicate with a C++ MA. A similar interface appears in the SeD communication process.
