Flex 3 profiling without FlexBuilder Pro

Although you can't use the profiler UI from FlexBuilder if you have no professional license, you can get some profiler stuff working if you do the following:

• find the ProfilerAgent.swf file in the .metadata\.plugins\com.adobe.flash.profiler folder of your eclipse workspace.


• edit/create mm.cfg (to be found/created in %USERPROFILE% on win xp), and add the following line:
  PreloadSwf=\ProfilerAgent.swf?host=localhost&port=9999, where you replace the with the actual path found in the previous step.
  

From now on, you can start to use things from the flash.sampler library (included with FlexBuilder), and call inspection methods like getSize, startSampling etc. (see Flex help) if you start your application in debug mode...
