Web services EJB+；生成进程上的Webservice错误

我是java初学者。我使用netbean创建项目JavaEE>EnterpriseApplication，从数据库中创建实体类，并创建JPA持久性（我不确定是否调用它）。所以当我创建ejb时，我已经完成了。我将使用web服务调用ejb。当我使用没有ejb类的web服务或调用ejb时，这就是我的问题所在。它可以构建和部署应用程序，但当我使用ejb时。我在bulid应用程序中出错。任何人都可以解释我为什么要解决这个问题

此错误生成过程

Deploying D:\Project\Source\Dev\PYS\PYSServices\PYSServices-war\dist\PYSServices-war.war

这是我的web服务源代码。我的问题是，当我键入annotation@EJB时，会发生这种情况。它无法编译并生成war文件。如果我不使用EJB，它可以成功构建并部署到jboss服务器

您可能需要在项目中激活/启用EJB规范。
确保在EJB中包含了所有必需的注释

希望这对您有所帮助
您应该发布您的代码，以帮助其他人可以帮助您。请检查您是否在类声明之前忘记了注释@WebService，否则，请尝试分离您的业务逻辑和web服务，使用会话bean管理您的JPA实体，并在web服务类中使用会话bean
