我尝试运行JXTA应用程序并得到以下异常......如何排序此问题？
我的代码是::
import net.jxta.platform.NetworkManager;
public class Main {
public static void main ( String args [ ] ) {
NetworkManager manager = null ;
try{
manager = new NetworkManager ( NetworkManager . ConfigMode . EDGE , "HelloWorld " ) ;
System . out . println ( " S t a r t ing JXTA" ) ;
manager . startNetwork ( ) ;
System . out . println ( " JXTA St a r t ed " ) ;
} catch ( Exception e ) {
e . printStackTrace ( ) ;
}
}
}
例外是::

答案 0 :(得分：3)
这不是错误，这只是默认日志JXTA。
尝试将此行放在函数main()的开头：
System.setProperty(Logging.JXTA_LOGGING_PROPERTY, Level.OFF.toString());
