I am working on a gwt-Evaluation project and we are working with
smartgwt, our first goal was to simply make a GUI working with local
TestData. Now we are supposed to split the client code from the
TestData which should be moved to the server. So I need to make RPC
calls to get the necessary data from the server services all the time
but I have a hard time getting it to work because of non-serializable
types I guess. This is a simplyfied code example.
My user-defined Class is not serializable it seems but I can't figure
out why.
ZeitbuchungDaten.class
[CODE]
package com.isp.ajaxtest.client;
import java.util.Date;
import com.google.gwt.user.client.rpc.IsSerializable;
public class ZeitbuchungDaten implements IsSerializable
{
private int idZeitbuchung;
private int idMitarbeiter;
private int idAuftrag;
private Date zeitpunktDerBuchung;
private int buchungsArt;
private double fertiggestelltInProzent;
private double geschaetzteRestzeitInStunden;
private boolean endeGebucht;
private int startIdZeitbuchung;
private int endeIdZeitbuchung;
private boolean storniert;
private String kommentarZurBuchung;
public ZeitbuchungDaten( int idZeitbuchung, int idMitarbeiter, int
idAuftrag, Date zeitpunktDerBuchung,
int buchungsArt )
{
this.setIdZeitbuchung( idZeitbuchung );
this.setIdMitarbeiter( idMitarbeiter );
this.setIdAuftrag( idAuftrag );
this.setZeitpunktDerBuchung( zeitpunktDerBuchung );
this.setBuchungsArt( buchungsArt );
this.setFertiggestelltInProzent( fertiggestelltInProzent );
this.setGeschaetzteRestzeitInStunden
( geschaetzteRestzeitInStunden );
this.setEndeGebucht( endeGebucht );
this.setStartIdZeitbuchung( startIdZeitbuchung );
this.setEndeIdZeitbuchung( endeIdZeitbuchung );
this.setStorniert( storniert );
this.setKommentarZurBuchung( kommentarZurBuchung );
}
//Setter+Getter
}
[/CODE]
FakeDatenService.java
[CODE]
package com.isp.ajaxtest.client;
import java.util.List;
import com.google.gwt.user.client.rpc.RemoteService;
import com.google.gwt.user.client.rpc.RemoteServiceRelativePath;
@RemoteServiceRelativePath("fakeDaten")
public interface FakeDatenService extends RemoteService {
List<ZeitbuchungDaten> getAlleZeitbuchungen();
List<ZeitbuchungDaten> getAlleZeitbuchungenByIdAuftrag(int
idAuftrag);
}
[/CODE]
Same for FakeDatenServiceAsync.java
FakeDatenServiceImpl.java
[CODE]
package com.isp.ajaxtest.server;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
import com.isp.ajaxtest.client.ZeitbuchungDaten;
public class FakeDatenServiceImpl extends RemoteServiceServlet
implements FakeDatenService
{
final List<ZeitbuchungDaten> alleZeitbuchungen = new
ArrayList<ZeitbuchungDaten>();
@SuppressWarnings("deprecation")
public FakeDatenServiceImpl()
{
//Test Date Object
final Date date = new Date();
date.setDate( 22 );
date.setYear( 108 );
date.setMonth( 7 );
//ZeitbuchungDatenContainer
final ZeitbuchungDaten testZeitbuchung1 = new ZeitbuchungDaten( 1,
1, 1, date, 0 );
testZeitbuchung1.setEndeGebucht( true );
testZeitbuchung1.setEndeIdZeitbuchung( 2 );
alleZeitbuchungen.add( testZeitbuchung1 );
//many more hard-coded ZeitbuchungDatenObjects....
}
public List<ZeitbuchungDaten> getAlleZeitbuchungen()
{
return alleZeitbuchungen;
}
public List<ZeitbuchungDaten> getAlleZeitbuchungenByIdAuftrag(int
idAuftrag)
{
List<ZeitbuchungDaten> alleZeitbuchungenByIdAuftrag = new
ArrayList<ZeitbuchungDaten>();
for(int i = 0; i<alleZeitbuchungen.size();i++)
{
if(alleZeitbuchungen.get( i ).getIdAuftrag()==idAuftrag)
{
alleZeitbuchungenByIdAuftrag.add( alleZeitbuchungen.get(i) );
}
}
return alleZeitbuchungenByIdAuftrag;
}
}
[/CODE]
When I dont implement IsSerializable in ZeitbuchungDaten I get the GUI
running until I trigger the RPC call which results in this error:
"Caused by: com.google.gwt.user.client.rpc.SerializationException:
Type 'com.isp.ajaxtest.client.ZeitbuchungDaten' was not included in
the set of types which can be serialized by this SerializationPolicy
or its Class object could not be loaded. For security purposes, this
type will not be serialized."
When I implement it, I get this error immediately:
