我使用netfishs 6.7.1和glassfish v2.1编写了一个Web服务项目，将log4j.properties放入项目的根目录并使用：

static Logger logger = Logger.getLogger(MyClass.class);

在构造函数中：

PropertyConfigurator.configure("log4j.properties");

在功能上：

logger.info("...");
logger.error("...");
// ...

但是，这是错误信息（实际上，我已经尝试将它几乎可以实现的每个目录都放入）：

log4j:ERROR Could not read configuration file [log4j.properties].
