First aid when emulator doesn't start
By Tomas Brandalik on Feb 15, 2010

We have got few bug reports about not starting emulator. After some research we would like to summarize possible causes.

1. Freshly installed windows doesn't have msvcrtXX.dlls

Got to folder runtimes\\cdc-hi\\bin and copy Microsoft.VC80.CRT into runtimes\\cldc-hi-javafx\\bin. This problem will be fixed over autoupdate soon.

2. Problem with localhost

Please edit <javamesdk_installdir>\\toolkit-lib\\modules\\bootstrap\\conf\\system.properties and change
device-manager.object-registry.host=localhost to: device-manager.object-registry.host=127.0.0.1

3. Port 1299 might be taken

Please edit <javamesdk_installdir>\\toolkit-lib\\modules\\bootstrap\\conf\\system.properties and change
device-manager.object-registry.port=1299 to: device-manager.object-registry.port=1999

4. XP 64-bit

Please use 32-bit version of JDK.

5. Firewall

Make sure that firewall is not blocking communication on ports given in 3. Default port numbers are 1299 for windows and 1999 for Mac.
