Oracle Java ME SDK uses the log4j logging facility to manage Device Manager and Device Instance logs.
The device manager log is placed into:
userhome\javame-sdk\
version\log\device-manager.log
Logging levels can be configured in the following XML file:
installdir\toolkit-lib\process\device-manager\conf\log4j.xml
A priority value for the categories com.sun
or VM can be set to the following levels: ERROR, WARN, INFO, DEBUG, TRACE (ordered from least to most verbose).
<category name="com.sun"> <priority value="DEBUG"/> <appender-ref ref="CONSOLE-ALL"/> <appender-ref ref="FILE"/> </category> <category name="VM"> <priority value="INFO"/> <appender-ref ref="CONSOLE-ALL"/> <appender-ref ref="FILE"/> </category>
Each device (or emulator) instance writes its own log into its directory. See Table 8-1 to correlate the emulator number and the device name.
userhome\javame-sdk
\version\work\
device-name\device.log
log4j.xml
controls the verbosity of the device instance logs, as described in Section 15.1, "Device Manager Logs".
