-Djava.util.logging.config.file="logging.properties" 
                                "logging.properties" is the path to a file containing logging configuration. 

For relative paths, the working directory of the process is significant.

In that file, include a line like this:
.level= INFO

    This sets the global level, which can be overridden for specific handlers and loggers. For example, a specific logger's level can be overridden like this:
    com.xyz.foo.level = SEVERE

     You can get a template for a logging properties file from jre6\lib\logging.properties.

Filter

Logger rootLogger = LogManager.getLogManager().getLogger("");
rootLogger.setFilter(new Filter() {
    @Override
    public boolean isLoggable(LogRecord record) {
            return "something".equals(record.getLoggerName());
    }
});

Logger rootLogger = LogManager.getLogManager().getLogger("");

rootLogger.setFilter(new Filter() {

@Override

public boolean isLoggable(LogRecord record) {

return "something".equals(record.getLoggerName());

}

});
