12 Logs

Oracle Java ME SDK uses the log4j logging facility to manage Device Manager and Device Instance logs.

12.1 Device Manager Logs

The device manager log is placed into:

userhome\javame-sdk\3.2\work\devicename\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>

12.2 Device Instance Logs

Each device (or emulator) instance writes its own log into its directory. See Table 6-1 to correlate the emulator number and the device name.

userhome\javame-sdk\version\work\devicename\device.log

log4j.xml controls the verbosity of the device instance logs, as described in Section 12.1, "Device Manager Logs."
