Glassfish-java.lang.NoClassDefFoundError

Question

我正在關注此博客以在glasshfish中運行示例Websocket應用程序。 部署失敗，並出現以下錯誤。 但是提到的類文件在pom.xml中可用，並且在依賴項中也列出了它。 能否請你幫忙？

The module has not been deployed.
See the server log for details.

Answer 1

解決了。 glassfish的modules文件夾和WEB-INF \\ lib文件夾中不應有相同的jar。

Answer 2

您可能只需要清理並構建您的項目。
