Glassfish-java.lang.NoClassDefFoundError

Question

我正在关注此博客以在glasshfish中运行示例Websocket应用程序。 部署失败，并出现以下错误。 但是提到的类文件在pom.xml中可用，并且在依赖项中也列出了它。 能否请你帮忙？

 Error occurred during deployment: Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: java.lang.NoClassDefFoundError: org/glassfish/websocket/spi/Endpoint. Please see server.log for more details.
The module has not been deployed.
See the server log for details.

Answer 1

解决了。 glassfish的modules文件夹和WEB-INF \\ lib文件夹中不应有相同的jar。

Answer 2

您可能只需要清理并构建您的项目。
