[Beepcore-java-users] Implenting LogService using java.util.logging in j2se

[Serge A. <sA...@in...>]

Hi,

The following code is an implementation of the beepcore-java LogService
interface using the new logging package provided by the JDK 1.4.0.
The beep2j2se is a tentative to convert severity to level.
