java - Glassfish - java.lang.NoClassDefFoundError

Question

我在关注这个 blog在 glasshfish 中运行示例 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，它也列在依赖项中。你能帮忙吗？

 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

已解决。你不应该在 glassfish 的模块文件夹和 WEB-INF\lib 文件夹中有相同的 jar。
