Glassfish - java.lang.NoClassDefFoundError

Question

我正在关注这个博客,在glasshfish中运行一个示例websocket应用程序.部署失败,出现以下错误.但是提到的类文件在pom.xml中可用,它也在依赖项中列出.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.你不应该在glassfish的模块文件夹和WEB-INF\lib文件夹中使用相同的jar.
