commons-attributes-compiler.jar]: Required extension qdox not found问题
2007-08-06 17:49
之所以采用MyEclipse5.5M2主要时看重这个版本的MyEclipse集成了最新的Spring2.0版本。这个系统采用了SSH框架结构，由于是初次使用，而且人员经验有限，遇到了比较多的问题，其中Error getConfigured / ExtensionValidator error错误是困扰了我两天的问题。 出现这个问题的条件是使用MyEclipse5.5M2，并且使用Spring Core包。 问题的表现形式是，当把项目部署到Tomcat服务器时，出现如下错误：  INFO: Deploying web application archive TestSpringMVC.warAug 18, 2006 10:21:13 AM org.apache.catalina.util.ExtensionValidator validateManifestResourcesINFO: ExtensionValidator[/TestSpringMVC][commons-attributes-api.jar]: Required extension "ant" not found.Aug 18, 2006 10:21:13 AM org.apache.catalina.util.ExtensionValidator validateManifestResourcesINFO: ExtensionValidator[/TestSpringMVC][commons-attributes-compiler.jar]: Required extension "ant" not found.Aug 18, 2006 10:21:13 AM org.apache.catalina.util.ExtensionValidator validateManifestResourcesINFO: ExtensionValidator[/TestSpringMVC][commons-attributes-compiler.jar]: Required extension "javadoc" not found.Aug 18, 2006 10:21:13 AM org.apache.catalina.util.ExtensionValidator validateManifestResourcesINFO: ExtensionValidator[/TestSpringMVC]: Failure to find 3 required extension(s).Aug 18, 2006 10:21:13 AM org.apache.catalina.core.StandardContext startSEVERE: Error getConfiguredAug 18, 2006 10:21:13 AM org.apache.catalina.core.StandardContext startSEVERE: Context [/TestSpringMVC] startup failed due to previous errorsAug 18, 2006 10:21:13 AM org.apache.catalina.core.StandardContext stopINFO: Container org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/TestSpringMVC] has not been started这个问题出现的原因是commons-attributes-compiler.jar包的MANIFEST.MF文件出现问题，如果对这个包没有依赖，直接删除这个包的引用，项目就可以正常启动，如果对这个包有依赖，那么可以通过以下两种方式来解决。 1、修改MANIFEST.MF文件 原compiler.jar包中的MF文件结构 Manifest-Version: 1.0Ant-Version: Apache Ant 1.5.3 Created-By: Apache MavenBuilt-By: henPackage: org.apache.commons.attributesBuild-Jdk: 1.4.2_05Extension-Name: commons-attributes-apiSpecification-Title: Client API for Jakarta Commons Attributes.Specification-Vendor: The Apache Software FoundationImplementation-Title: org.apache.commons.attributesImplementation-Vendor: The Apache Software FoundationImplementation-Version: 2.2Extension-List: ant qdoxant-Extension-Name: antant-Implementation-Version: 1.5ant-Implementation-URL: http://www.ibiblio.org/maven/ant/jars/ant-1.5. jarqdox-Extension-Name: qdoxqdox-Implementation-Version: 1.5qdox-Implementation-URL: http://www.ibiblio.org/maven/qdox/jars/qdox-1 .5.jarImplementation-Vendor-Id: org.apacheX-Compile-Source-JDK: 1.4X-Compile-Target-JDK: 1.4Manifest-Version: 1.0Ant-Version: Apache Ant 1.5.3 Created-By: Apache MavenBuilt-By: henPackage: org.apache.commons.attributesBuild-Jdk: 1.4.2_05Extension-Name: commons-attributes-apiSpecification-Title: Client API for Jakarta Commons Attributes.Specification-Vendor: The Apache Software FoundationImplementation-Title: org.apache.commons.attributesImplementation-Vendor: The Apache Software FoundationImplementation-Version: 2.2Extension-List: ant qdoxant-Extension-Name: antant-Implementation-Version: 1.5ant-Implementation-URL: http://www.ibiblio.org/maven/ant/jars/ant-1.5.jarqdox-Extension-Name: qdoxqdox-Implementation-Version: 1.5qdox-Implementation-URL: http://www.ibiblio.org/maven/qdox/jars/qdox-1.5.jarImplementation-Vendor-Id: org.apacheX-Compile-Source-JDK: 1.4X-Compile-Target-JDK: 1.42、替换compiler.jar包 下载，将我提供的jar包下载之后替换也可以解决这个问题 |
