Java 严重：加载WebappClassLoader时出错

java web-services maven tomcat servlets

Java 严重：加载WebappClassLoader时出错,java,web-services,maven,tomcat,servlets,Java,Web Services,Maven,Tomcat,Servlets,我正在使用JAX-RSRESTEasy和java开发一个Web服务。 我首先使用了jersey_bundle-1.17.1 maven，如这里所述。在此之前，我使用了jersey_bundle-1.12。它们都不起作用。之后，根据错误，我在jarfiles中搜索了com.sun.jersey.spi.container.servlet.ServletContainer包，并在那里找到了它。但我使用的是maven，我在maven中搜索，却没有找到它在那里（但我把它们添加到了我的pom.xml中）。

请打开WAR文件并检查是否存在所需的新泽西依赖项，好吗？我觉得你的POM不错。TimBiegeleisen我会检查并重播。我还有一个dobt。你能检查我的web.xml来检查我的servlet名称吗？特别是我定义的我的…。这件事在我的应用程序中显示为错误。在其他地方，我发现org.glassfish.etc…包含com.sun.jersey.spi.container.servlet.ServletContainer。我正在使用tomcat 6.0你的
web.xml
外观好的如果这是一个问题，那么您在尝试实例化
ServletContainer
类时会遇到错误。请检查正在部署的战争；我敢打赌它缺少Jersey依赖项。好的，Tim Biegeleisen。关于尝试实例化ServletContainer时出错的问题…谢谢。我将检查我的WAR，并肯定会回复…@TimBiegeleisen按照您上面提到的方式提取WAR文件。它显示类、web.xml和库。我的库文件夹为空。
