Question

weblogic上部署war包时报java.lang.NullPointerException错误，求各位大神指导

附上日志：
User defined listener com.cait.waf.webcontainer.ContextListener failed: java.lang.NullPointerException. java.lang.NullPointerException at com.cait.waf.webcontainer.Lifecycle.contextInitialized(Lifecycle.java:67) at com.cait.waf.webcontainer.ContextListener.contextInitialized(ContextListener.java:18) at weblogic.servlet.internal.EventsManager$FireContextListenerAction.run(EventsManager.java:481) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321) at weblogic.security.service.SecurityManager.runAs(SecurityManager.java:121) at weblogic.servlet.internal.EventsManager.notifyContextCreatedEvent(EventsManager.java:181) at weblogic.servlet.internal.WebAppServletContext.preloadResources(WebAppServletContext.java:1863) at weblogic.servlet.internal.WebAppServletContext.start(WebAppServletContext.java:3126) at weblogic.servlet.internal.WebAppModule.startContexts(WebAppModule.java:1512) at weblogic.servlet.internal.WebAppModule.start(WebAppModule.java:486) at weblogic.application.internal.flow.ModuleStateDriver$3.next(ModuleStateDriver.java:425) at weblogic.application.utils.StateMachineDriver.nextState(StateMachineDriver.java:41) at weblogic.application.internal.flow.ModuleStateDriver.start(ModuleStateDriver.java:119)
从新部署后又报错：Failure occurred in the execution of deployment request with ID '1406621975598' for task '10'. Error is: 'weblogic.application.ModuleException: ' weblogic.application.ModuleException: at weblogic.servlet.internal.WebAppModule.startContexts(WebAppModule.java:1514) at weblogic.servlet.internal.WebAppModule.start(WebAppModule.java:486) at weblogic.application.internal.flow.ModuleStateDriver$3.next(ModuleStateDriver.java:425)

Answer 1

可能是因为 com.cait.waf.webcontainer.Lifecycle.contextInitialized 里面有问题
变量引用为null, 导致 NullPointerException

Answer 2

User defined listener com.cait.waf.webcontainer.ContextListener failed:

去查查Web.xml
