在weblogic11g上发布项目遇到的一个错误（不支持web-app_3_0）

错误信息如下：

消息图标 - 错误 [HTTP:101064][WebAppModule(ssh1:ssh1.war)] Error parsing descriptor in Web appplication "/web/ssh1.war" weblogic.application.ModuleException: VALIDATION PROBLEMS WERE FOUND problem: cvc-enumeration-valid: string value '3.0' is not a valid enumeration value for web-app-versionType in namespace http://java.sun.com/xml/ns/javaee:<null> at weblogic.servlet.internal.WebAppModule.loadDescriptor(WebAppModule.java:1345) at weblogic.servlet.internal.WebAppModule.prepare(WebAppModule.java:374) at weblogic.application.internal.flow.ScopedModuleDriver.prepare(ScopedModuleDriver.java:176) at weblogic.application.internal.flow.ModuleListenerInvoker.prepare(ModuleListenerInvoker.java:199) at weblogic.application.internal.flow.DeploymentCallbackFlow$1.next(DeploymentCallbackFlow.java:517) at weblogic.application.utils.StateMachineDriver.nextState(StateMachineDriver.java:52) at weblogic.application.internal.flow.DeploymentCallbackFlow.prepare(DeploymentCallbackFlow.java:159) at weblogic.application.internal.flow.DeploymentCallbackFlow.prepare(DeploymentCallbackFlow.java:45) at weblogic.application.internal.BaseDeployment$1.next(BaseDeployment.java:648) at weblogic.application.utils.StateMachineDriver.nextState(StateMachineDriver.java:52) at weblogic.application.internal.BaseDeployment.prepare(BaseDeployment.java:191) at weblogic.application.internal.SingleModuleDeployment.prepare(SingleModuleDeployment.java:44) at weblogic.application.internal.DeploymentStateChecker.prepare(DeploymentStateChecker.java:154) at weblogic.deploy.internal.targetserver.AppContainerInvoker.prepare(AppContainerInvoker.java:60) at weblogic.deploy.internal.targetserver.operations.RedeployOperation.createAndPrepareContainer(RedeployOperation.java:104) at weblogic.deploy.internal.targetserver.operations.RedeployOperation.doPrepare(RedeployOperation.java:128) at weblogic.deploy.internal.targetserver.operations.AbstractOperation.prepare(AbstractOperation.java:217) at weblogic.deploy.internal.targetserver.DeploymentManager.handleDeploymentPrepare(DeploymentManager.java:747) at weblogic.deploy.internal.targetserver.DeploymentManager.prepareDeploymentList(DeploymentManager.java:1216) at weblogic.deploy.internal.targetserver.DeploymentManager.handlePrepare(DeploymentManager.java:250) at weblogic.deploy.internal.targetserver.DeploymentServiceDispatcher.prepare(DeploymentServiceDispatcher.java:159) at weblogic.deploy.service.internal.targetserver.DeploymentReceiverCallbackDeliverer.doPrepareCallback(DeploymentReceiverCallbackDeliverer.java:171) at weblogic.deploy.service.internal.targetserver.DeploymentReceiverCallbackDeliverer.access$000(DeploymentReceiverCallbackDeliverer.java:13) at weblogic.deploy.service.internal.targetserver.DeploymentReceiverCallbackDeliverer$1.run(DeploymentReceiverCallbackDeliverer.java:46) at weblogic.work.SelfTuningWorkManagerImpl$WorkAdapterImpl.run(SelfTuningWorkManagerImpl.java:545) at weblogic.work.ExecuteThread.execute(ExecuteThread.java:256) at weblogic.work.ExecuteThread.run(ExecuteThread.java:221) Caused by: weblogic.descriptor.DescriptorException: VALIDATION PROBLEMS WERE FOUND problem: cvc-enumeration-valid: string value '3.0' is not a valid enumeration value for web-app-versionType in namespace http://java.sun.com/xml/ns/javaee:<null> at weblogic.descriptor.internal.MarshallerFactory$1.evaluateResults(MarshallerFactory.java:245) at weblogic.descriptor.internal.MarshallerFactory$1.evaluateResults(MarshallerFactory.java:231) at weblogic.descriptor.internal.MarshallerFactory$1.createDescriptor(MarshallerFactory.java:155) at weblogic.descriptor.BasicDescriptorManager.createDescriptor(BasicDescriptorManager.java:323) at weblogic.application.descriptor.AbstractDescriptorLoader2.getDescriptorBeanFromReader(AbstractDescriptorLoader2.java:788) at weblogic.application.descriptor.AbstractDescriptorLoader2.createDescriptorBean(AbstractDescriptorLoader2.java:409) at weblogic.application.descriptor.AbstractDescriptorLoader2.loadDescriptorBeanWithoutPlan(AbstractDescriptorLoader2.java:759) at weblogic.application.descriptor.AbstractDescriptorLoader2.loadDescriptorBean(AbstractDescriptorLoader2.java:768) at weblogic.servlet.internal.WebAppDescriptor.getWebAppBean(WebAppDescriptor.java:141) at weblogic.servlet.internal.WebAppModule.loadDescriptor(WebAppModule.java:1331) ... 26 more weblogic.application.ModuleException: VALIDATION PROBLEMS WERE FOUND problem: cvc-enumeration-valid: string value '3.0' is not a valid enumeration value for web-app-versionType in namespace http://java.sun.com/xml/ns/javaee:<null>

　　因为创建项目的时候用的是JAVAEE6，所以生成web.xml文件的时候是这样的：

<web-app version="3.0"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

　　weblogic11g并不支持web-app_3_0.xsd的定义。所以报错了。

　　改为如下就ok了：

<web-app version="2.5"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
