Question

我们正在尝试从JBoss4.2.3迁移到Wildfly，当我们尝试将战争从JBoss4.2.3部署到Wildfly11时，我们遇到以下异常：

更新1： 我已经尝试手动将Apache commons日志记录jar文件添加到modules文件夹中，但在这种情况下它会出现以下错误：

Caused by: org.apache.commons.discovery.DiscoveryException: Class org.apache.commons.logging.impl.LogFactoryImpl does not implement org.apache.commons.logging.LogFactory
        at org.apache.commons.discovery.tools.ClassUtils.verifyAncestory(ClassUtils.java:180)
        at org.apache.commons.discovery.tools.SPInterface.verifyAncestory(SPInterface.java:201)

   <resource-root path="commons-httpclient-3.1.jar"/>
   <resource-root path="commons-logging-1.0.4.jar"/>
</resources>
</module>

UPDATE2： 通过引用以下线程创建了common-logging.properties文件，但仍然出现此错误

Caused by: org.apache.commons.discovery.DiscoveryException: Class org.apache.commons.logging.impl.LogFactoryImpl does not implement org.apache.commons.logging.LogFactory

JavaAgent in Lotus Notes 6.5 using axis api gives Exception "No implementation defined for org.apache.commons.logging.LogFactory"

这是commons-logging-jboss-logmanager项目中的“错误”，已在1.0.3.Final中修复。问题是某些项目似乎重新打包commons-logging并添加META-INF/services/org.apache.commons.logging.LogFactory文件，默认commons-logging:commons-logging JAR似乎没有。

下载org.jboss.logmanager:commons-logging-jboss-logmanager:1.0.3.Final并更换模块应该是安全的。您只需将下载的库放在$JBOSS_HOME/modules/system/layers/base/org/jboss/logmanager/commons/logging/main/中，然后编辑module.xml以指向新版本。

没有为org.apache.commons.logging.LogFactory定义实现
