我开发了一个Android应用程序,现在我开始使用其外部数据库及其服务器,通信由RESTful Web服务执行.

这个Android应用程序只生成和使用JSON中的信息,因此在我的Web服务外观中,我只想删除CRUD方法中对XML的任何提及(由NetBeans自动生成).

我的意思是,从这个:

@GET
@Override
@Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public List<Counselor> findAll() {
    return super.findAll();
}

对此(没有MediaType.APPLICATION_XML):

@GET
@Override
@Produces(MediaType.APPLICATION_JSON)
public List<Counselor> findAll() {
    return super.findAll();
}

问题是当我在我的GlassFish Server(4.1.1)中部署这些更改并使用我的浏览器进行一些测试时(只是想查看我的数据库数据),我得到了一个错误,这个堆栈跟踪:
