EJB parameter for marshaling a ClassNotFoundException

I am doing a project with distributed architectures, but I am having trouble returning java.util.Collection to the client application.

I invoke an EJB in a managed Bean to fetch a collection of persistent objects.

I am using Java7 and JBoss7.1.1.

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 Method:

 public Collection<Cliente> getCarteira() { carteira = clienteDao.read(Cliente.QUERY_ALL); return carteira; }

The clienteDao.read(Cliente.QUERY_ALL) method, finds entities and populates the collection. However, returning to a managed Bean, we have a stack trace:

Place the jboss-deployment-structure.xml file in the 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>
