java - 如何在EAR项目中部署EJB项目和JPA项目

Question

我创建了2个项目，一个是EJB，一个是JPA。 JPA项目定义实体类和perpetual.xml。 EBJ项目导入JPA项目，我定义了EJB session bean来通过实体管理器连接数据库。详情请参阅下图。但是在Jboss 7上运行时，出现错误。

我失败了。任何人都可以纠正我，告诉我如何部署(jpa项目和ejb项目在同一个耳朵)。

Answer 1

您有 2 个潜在的选择:

• 如果 TestJpa.jar 位于 ear\lib 文件夹中，默认情况下它应该在 ejb 模块中可见(确保 EAR 位于 6.0 中) > 版本)
• 通过 EJB 项目、JPA 项目中的部署程序集手动添加 - 应该会导致 EJB 模块的 list 文件发生更改。

如果您正确配置它，无论使用哪种方式，您都应该在 Eclipse 的 EJB Module > EAR Libraries 中看到 JPA 项目，而无需将其添加为构建路径中的项目
