JPA实体加入问题（我认为）

即时通讯使用JPA和有问题，即时通讯使用实体生成的东西（太累了，不能想到名字）在我的持久性文件，所以我的实体达到划痕。但即时通讯有问题加入他们。JPA实体加入问题（我认为）

我的问题是，我不认为IM加入该实体正确

调用从（与EM注入豆）

public Department getDepartment(int id){ 
    Department dep = null; 
    dep = em.find(Department.class,id); 
return dep; 
}

部

持续添加，谢谢你看一看Bozho – Jon 2010-09-12 22:15:17

你的主键（标有@Id）为int，而你尝试通过Long到em.find(..) - 改为通过int。

我改变了这一点（不能相信我相信它），不幸的是，我试图得到一个错误。我会试着修改上述内容 – Jon 2010-09-12 20:53:35

看起来您正在使用Web Service，并且响应的内容与WSDL不匹配。

引起：com.sun.xml.ws.streaming.XMLStreamReaderException：意外的XML标记。预计：{} http://test.com/但getDepartmentResponse发现：{} http://schemas.xmlsoap.org/soap/envelope/信封

你是如何构建的反应如何？
