VisualVM understands Java ME Profiler Snapshot

Java ME SDK 3.0 supports offline profiling. Data is collected during the emulation session. After you close the emulator a profiler data snapshot is written to a .prof file which you can load and view in the SDK.

Since last Friday it is possible to load and view Java ME SDK profiler file also in VisualVM 1.1. VisualVM is a tool to monitor and troubleshoot Java applications. For more information about VisualVM visit its homepage.

How to view Java ME SDK profiler file in VisualVM? It's easy. Everything you have to do is to install Java ME Profiler Snapshot Viewer module from VisualVM update center.

  1. Start VisualVM.
