Question

我创建了一个名为EnterpriseApplication6的JavaEE项目我在EnterpriseApplication6-ejb中创建一个新的SessionBean，其名称为NewSessionBean，其Session类型为无状态，具有本地接口我在EnterpriseApplication6中创建了一个名为NewServlet的新Servlet 当我在NewServlet中声明NewSessionBean时出现问题，然后会出现此错误： 1- NewServlet将像这样运行[] :( https://www.dropbox.com/s/rssmhvtu5kzor05/Untitled.png） 2-出现此错误这是错误 C：\ Users \ AdminPC \ Documents \ NetBeansProjects \ EnterpriseApplication6 \ nbproject \ build-impl.xml：307：尚未部署模块。有关详细信息，请参阅服务器日志。

当我删除声明时，项目将是Ok 我该如何解决这个问题？
