我有一个小问题，但在任何地方都找不到答案 - 当使用 mule jar 将 mule 应用程序（war）部署到 tomcat 中时，我看到以下消息：

SEVERE: Exception sending context initialized event to listener instance of class org.mule.config.builders.MuleXmlBuilderContextListener

这很糟糕，因为 org.mule.context.notification.MuleContextNotification 正在扩展 org.mule.api.context.notification.ServerNotification。我在这里想念什么？

好的，我找到了解决方案：

1 - 首先最好在 WEB-INF\classes logging.properties 文件中有：

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

这样所有正确的错误都会显示在控制台上，很可能会有 ClassNotFoundException。

2 - 通过 maven 依赖项将所需的 lib 导入您的应用程序（对我来说，我必须使用提供的范围，因为 jar 已经在 tomcat lib 目录中） - 在我的情况下，它是 mule-module-tomcat-3.4.0.jar

最后我的项目的 pom.xml 看起来像这样：

...
<properties>
  <spring.version>3.2.3.RELEASE</spring.version>
  <mule.version>3.4.0</mule.version>
</properties>

<dependencies>
  <dependency>
      <groupId>org.mule</groupId>
      <artifactId>mule-core</artifactId>
      <version>${mule.version}</version>
      <scope>provided</scope>
  </dependency>

  <dependency> 
      <groupId>org.mule.modules</groupId> 
      <artifactId>mule-module-spring-config</artifactId>
      <version>${mule.version}</version> 
      <scope>provided</scope>
  </dependency>

  <dependency>
      <groupId>org.mule.modules</groupId>
      <artifactId>mule-module-tomcat</artifactId>
      <version>${mule.version}</version>
      <scope>provided</scope>
  </dependency>

  <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>
      <version>${spring.version}</version>
      <scope>provided</scope>
  </dependency> 
</dependencies>

问题解决了：D
