Overview

The OSGi Emulator is a tool for Eclipse which enables developers to emulate an OSGi Runtime image on a computer without the need to deploy the image on a real device. Thus, developers can test, debug and profile bundles - either developed in Eclipse or available at a location external to the IDE.

General

When emulation is launched, the OSGi Emulator relies on the Image Builder to create an image of the OSGi Runtime according to specified preferences and then launches the OSGi framework.

The components inside an emulated OSGi Runtime as well as the libraries needed for its launch are retrieved from the runtime part of the SDK specified by the mToolkit preference. Hence, to be able to use the emulator, you must have the runtime on the computer as well.

Emulation Modes

In general, there are three modes of OSGi runtime emulation:

• Plain mode – The emulation will be launched in the conventional way for Java applications, that is, as a closed process counting on the OSGi framework and the bundles in it to provide information about the operation of the system.
• Debug mode – During emulation, you will receive debug information about the behavior of the OSGi runtime and of the applications residing in it. The arriving data can be conveniently examined in the Java debugger of Eclipse.
• Profile mode – During emulation, you will receive profiling information for analyzing the performance of the OSGi platform and applications installed in it. You can use the mBProfiler to view incoming information in a friendly way.
