J2me 中使用 Log， 可以使用搜索引擎搜索下載 log4j2me.
使用方法和 j2se 中有一些區別，下面是在 log4j2me 包中的一個例子
package log4j2me.test;
import org.apache.log4j.*;
import org.apache.log4j.helpers.LogLog;
/**
Very simple log4j usage example.

public class Hello {
static Category log = Category.getInstance(Hello.class);
static Category log1 = Category.getInstance("Hello");
public static void main(String argv[]) {
Category root = Category.getRoot();
root.setPriority( Priority.DEBUG );
Layout layout = new PatternLayout("%p [%t] %c - %m%n");
try {
root.addAppender(new FileAppender(layout, System.out));
} catch(Exception e) {
LogLog.warn("Could not open file appender.");
}
log.debug("Hello world.");
log.info("What a beatiful day.");
log1.debug("Hello world.");
log1.info("What a beatiful day.");
}
}
