configuration - How do I get log4J to work - I'm getting "package org.apache.log4j does not exist" -

i know may newbie qestion, i'm having issues setting log4j:

i want run log4j demo, , here's code:

import org.apache.log4j.logger; import org.apache.log4j.basicconfigurator; public class hellolog4j { private static final logger logger = logger.getlogger(hello.class); public static void main(string argv[]) { basicconfigurator.configure(); logger.debug("hello world."); logger.info("what beatiful day."); } }

i set classpath: c:\users\adel\downloads\apache-log4j-1.2.17\log4j-1.2.17.jar in both scheme , user var's

but when run programme still get

errors found: file: c:\users\adel\desktop\various_topics\javaprojects\hellolog4j.java [line: 2] error: bundle org.apache.log4j not exist

i know set classpath right - if run cmd line:

c:\program files\java\jdk1.6.0_20>print %log4j_home% c:\users\adel\downloads\apache-log4j-1.2.17\log4j-1.2.17.jar bein g printed

you neeed add together log4j home classpath jvm needs path log4j classes

if on windows can utilize

set classpath=%classpath%;%log4j_home%

then run app after adding other paths classpath

set classpath=%classpath%;c:\users\adel\....

do not need add together log4jhome 1 time again - %classpath% add together current.

log4j_home not known java used log4j in case of auto config/default config

on side note seek using new log4j2 !

configuration log4j log4
