Question

我在mule esb和servlet中使用Dynamicax，在tomcat中创建war文件并进行部署，当我运行它时会出现以下错误：

exception 
javax.servlet.ServletException: Servlet execution threw an exception
    org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)

我尝试使用以下依赖项，但它给了我Http错误404

<dependency>
                <groupId>org.mule.modules</groupId>
                <artifactId>mule-module-devkit-support</artifactId>
                 <version>3.7.2</version>
                  <scope>provided</scope>
        </dependency>

Answer 1

从您的依赖项中删除<scope>provided</scope>，您应该很高兴。

通过使用<scope>provided</scope>，您希望在运行时容器（在您的情况下为Tomcat）中依赖提供。但是tomcat肯定不包含这个jar文件。因此，您将获得NoClassDefFoundError。

尝试使用Dynamic Ax连接器时java.lang.NoClassDefFoundError：org / mule / streaming / ProviderAwarePagingDelegate
