Java JSF2.0包括ICEfaces组件，试图使用JPA2.0解决JBOSS独立服务器的持久性失败（nullpointException）
我试图编码一个小网站，它只使用一个表单。我使用EclipseIDE（indigo）和JBOSS作为7.1服务器。我已经使用JSF2.0和最新的ICEfaces组件编写了代码。现在我已经添加了JPA组件来读/写oracle数据库。实体是为一个示例表创建的，我能够映射到数据库。但在运行时，当我试图从bean调用实体管理器来获取持久化单元时，它会得到null值。我不知道我哪里做错了Java JSF2.0包括ICEfaces组件，试图使用JPA2.0解决JBOSS独立服务器的持久性失败（nullpointException）,java,jsf-2,jpa-2.0,jboss7.x,icefaces-3,Java,Jsf 2,Jpa 2.0,Jboss7.x,Icefaces 3,我试图编码一个小网站，它只使用一个表单。我使用EclipseIDE（indigo）和JBOSS作为7.1服务器。我已经使用JSF2.0和最新的ICEfaces组件编写了代码。现在我已经添加了JPA组件来读/写oracle数据库。实体是为一个示例表创建的，我能够映射到数据库。但在运行时，当我试图从bean调用实体管理器来获取持久化单元时，它会得到null值。我不知道我哪里做错了 @PersistenceUnit(unitName="jobApplication") private Enti
