菜鸟请问Jboss的错误堆栈信息在哪里？

[sixcolor]

在Jboss下部署了公司的web app，使用时出现NullPointerException的错误：

JBWEB000065: HTTP Status 500 - java.lang.NullPointerException

--------------------------------------------------------------------------------

JBWEB000309: type JBWEB000067: Status report

JBWEB000068: message java.lang.NullPointerException

JBWEB000069: description JBWEB000145: The server encountered an internal error that prevented it from fulfilling this request.

可是没有任何堆栈信息，查看C:\jboss-eap-6.4\standalone\log下面的server.log也没用任何堆栈信息，只是有提示下面的错误：
21:30:23,497 ERROR [stderr] (Start Level Event Dispatcher) log4j:WARN No appenders could be found for logger (org.apache.commons.digester.Digester).

21:30:23,497 ERROR [stderr] (Start Level Event Dispatcher) log4j:WARN Please initialize the log4j system properly.

请问各位高手，怎么才能看到这个NullPointerException的堆栈？是因为log4j配置得不对所有才看不到吗？需要怎么配置？

jboss的日志还是用的log4j，具体配置是在standalone/configuration下的logging.properties中，文件具体内容如下： loggers=jacorb,sun.rmi,org.jboss.as.config,jacorb.config,org.apache.tomcat.util.modeler,com.arjuna logger.level=INFO logger.handlers=FILE,CONSOLE logger.jacorb.level=WARN logger.jacorb.useParentHandlers=true logger.sun.rmi.level=WARN logger.sun.rmi.useParentHandlers=true logger.org.jboss.as.config.level=DEBUG logger.org.jboss.as.config.useParentHandlers=true logger.jacorb.config.level=ERROR logger.jacorb.config.useParentHandlers=true logger.org.apache.tomcat.util.modeler.level=WARN logger.org.apache.tomcat.util.modeler.useParentHandlers=true logger.com.arjuna.level=WARN logger.com.arjuna.useParentHandlers=true handler.CONSOLE=org.jboss.logmanager.handlers.ConsoleHandler handler.CONSOLE.level=INFO handler.CONSOLE.formatter=CONSOLE handler.CONSOLE.properties=autoFlush,target,enabled handler.CONSOLE.autoFlush=true handler.CONSOLE.target=SYSTEM_OUT handler.CONSOLE.enabled=true 具体需要添加什么，减少什么，楼主看着来吧
