我将 Netbeans 6.7 与 Tomcat 6.0 和 jasper 报告一起使用，以便在 Web 应用程序中生成报告。当我运行我的应用程序时，我总是会遇到这个异常。有人可以帮帮我吗？
异常(exception)情况是
INFO: Illegal access: this web application instance has been stopped already. Could not load org.apache.log4j.spi.NOPLoggerRepository. The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.
java.lang.IllegalStateException

最佳答案
这可能是由于内存问题，我收到了这条消息，还有一个 java.lang.OutOfMemoryError: Java heap space，调整启动参数为: -XX:PermSize=512M -Xms1024m -Xmx4096m 解决了这个问题。
关于java - 非法访问 : this web application instance has been stopped already. 无法加载 org.apache.log4j.spi.NOPLoggerRepository，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15827522/
