    Deployment Descriptor. An application-scoped resource is defined in the glassfish-resources.xml deployment descriptor file. 
    This file is placed in the META-INF directory of the module or application archive. For web applications or modules, 
    this file is placed in the WEB-INF directory. If any submodule archives of an enterprise application archive have their 
    own glassfish-resources.xml files, the resource definitions are scoped to those modules only. For more information about 
    the glassfish-resources.xml file, see Appendix B, GlassFish Server Deployment Descriptor Files and Appendix C, Elements of the 
    GlassFish Server Deployment Descriptors.

    Naming. Application-scoped resource JNDI names begin with java:app or java:module. If one of these prefixes is not specified 
    in the JNDI name, it is added. For example, application-scoped databases have JNDI names in the following format: 
    java:app/jdbc/DataSourceName or java:module/jdbc/DataSourceName. This is in accordance with the naming scopes introduced 
    in the Java EE 6 Specification.

我解决了它

堆栈跟踪的有趣部分位于末尾：原因：java.lang.IllegalStateException:在未指定LoadTimeWeaver的情况下无法应用类转换器

这里的解释帮助了我：

我仍然不知道如何在基于Java的应用程序上下文配置中从glassfish获得EntitManagerFactory作为JNDI。有什么想法吗？

谢谢你的回答。尽管如此，我还是不太明白。。。你能告诉我更多的细节吗？谢谢你的回答。尽管如此，我还是不太明白。。。你能告诉我更多的细节吗？
