目前我在glassfish 4上部署.ear文件时遇到问题。 这有一个JPA应用程序，我使用EJB启动会话模块来测试它。 当我在本地glassfish服务器上部署此应用程序时，出现以下错误。
“java.lang.NoClassDefFoundError：javax / persistence / EntityManager”。
我确保将所有必需的库包含在classpath中。任何人都可以帮我确定问题所在吗？
以下是完整的错误日志：

答案 0 :(得分：5)
获取javaee.jar文件并将其包含在项目类路径中。
http://mvnrepository.com/artifact/javax/javaee-api
或
您可以直接从以下链接下载
http://www.java2s.com/Code/Jar/j/Downloadjavaeeapi70jar.htm
javax.persistence.Entity是J2EE SDK库“javaee.jar”中的一个类，您在项目类路径中缺少此jar文件。
