Javamail 发送带附件邮件

使用时，要注意与其它mail包的冲突问题，如geronimo-javamail_1.4_spec-1.3.jar会导致邮件发出去的都是编码数据

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
这俩个包怎么导入的，
我导入你的程序后
private static Logger logger = LoggerFactory.getLogger(MailUtil.class);
LoggerFactory.getLogger(MailUtil.class)会报错，还有
logger.debug("发送邮件,邮件地址:" + emailAddr + " 标题:" + mailTitle  + " 内容:" + mailConcept + "成功!");
debug也会报错
怎么解决，你都导入了哪些jar包，能贴上来吗

添加 slf4j-api-1.5.8.jar
以及log4j的jar log4j-1.2.16.jar
