问题描述
我正在制作一个具有分布式体系结构的项目，但是在将java.util.Collection返回给客户端应用程序时遇到问题.
I am making a project with distributed architectures, but I am having problem in returning a java.util.Collection to the client application.
我在受管Bean中调用EJB来带来持久化实体的集合.
I am calling an EJB in a Managed Bean to bring a Collection of persisted entities.
我正在使用Java7和JBoss7.1.1.
I am using Java7 and JBoss7.1.1.
ManagedBean方法:
The ManagedBean method:
public Collection<Cliente> getClientes() {
clientes=new ArrayList<Cliente>();
try {
Context ctx = new InitialContext();
facade = (ClienteFacadeRemote) ctx.lookup(ClienteFacadeBean.NOME_EJB);
} catch (NamingException e) {
e.printStackTrace();
}
clientes = facade.getCarteira();
return clientes;
}
EJB方法:
public Collection<Cliente> getCarteira() {
carteira = clienteDao.read(Cliente.QUERY_ALL);
return carteira;
}
clienteDao.read(Cliente.QUERY_ALL)方法，找到实体并填充Collection.但是，返回到Managed Bean，我们有了堆栈跟踪:
The clienteDao.read(Cliente.QUERY_ALL) method, finds the entities and fill the Collection. However, returning to the Managed Bean, we have the stack trace:

推荐答案
在您的WEB-INF文件夹中放入文件jboss-deployment-structure.xml:
Put a file jboss-deployment-structure.xml in your WEB-INF folder:
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
<dependencies>
<module name="javaee.api" />
<module name="org.hibernate" />
</dependencies>
</deployment>
</jboss-deployment-structure>
