Hi all
Been searching these groups and the web in general to find an answer
to my question, but haven´t been able to wrap my head around what I´ve
found so far.
I´m playing around a bit trying to figure out how to make use of my
existing EJBs.
For example I have an existing EJB like this:
package intranet.apps.supplierdatabase;
import java.util.HashSet;
import java.util.Set;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.Id;
import javax.persistence.NamedQuery;
import javax.persistence.OneToMany;
import javax.persistence.Table;
/**
* SupplierLookup entity.
*
* @author MyEclipse Persistence Tools
*/
@NamedQuery (
name="getNameIdPairs",
query="select s.supplierName, s.supplierId FROM SupplierLookup
s"
)
@Entity
@Table(name = "SupplierLookup", schema = "dbo", catalog = "LevDB",
uniqueConstraints = {})
public class SupplierLookup
implements java.io.Serializable {
// Fields
private Integer supplierId;
private String supplierName;
private String supplierInfo;
private String supplierAddress;
(Getters and Setters)
}
My interfaces like this:
@RemoteServiceRelativePath("greet")
public interface GreetingService
extends RemoteService {
ArrayList<Supplier> getSuppliers() throws Exception;
}
public interface GreetingServiceAsync {
void getSuppliers(AsyncCallback<ArrayList<Supplier>> callback);
}
>From what I understand, I cannot reference my EJB in the GWT client
code, since most packages in my EJB is not part of the GWT JRE
emulation. So currently I have created a custom POJO which is pretty
much the same as my EJB without the EJB-part :-)
My test implementation looks like this:
public ArrayList<Supplier> getSuppliers() throws NamingException {
InitialContext ctx = new InitialContext();
SupplierLookupFacadeLocal supplier =
(SupplierLookupFacadeLocal)
ctx.lookup
(SupplierLookupFacade.LOCAL_JNDI_NAME);
ArrayList<SupplierLookup> all = new ArrayList
(supplier.findAll());
ArrayList<Supplier> suppliers = new
ArrayList<Supplier>();
for (SupplierLookup supplierLookup : all) {
Supplier supp = new Supplier();
supp.setSupplierAddress(supplierLookup.getSupplierAddress());
supp.setSupplierId(supplierLookup.getSupplierId());
supp.setSupplierInfo(supplierLookup.getSupplierInfo());
supp.setSupplierName(supplierLookup.getSupplierName());
suppliers.add(supp);
if (suppliers.size() >= 200) break;
}
return suppliers;
}
There just HAS to be a better way to do this? There must be a way to
send my EJB-POJO through RPC.
I´ve tried that aswell, but then I get an exception with reference to
the SerializationPolicy.
Any better solutions out there?
