Re: java.lang.NoClassDefFoundError: javax/validation/ValidationException
maybe you forgot to import gwt-servlet-deps.jar that contains the missing class ..

RequestFactory persist() error with hibernate
Hi, i'm trying to build a custom webapp using RequestFactory + Spring
+ Hibernate.
My goal is to build a table (using CellTable) where users can edit
some properties of the objects being displayed and then save them, but
anytime i call the persist() method i have an hibernate exception:
02:56:41,500 ERROR LazyInitializationException:42 - could not
initialize proxy - no Session

what i've done so far is:
- created EntityProxy (@ProxyFor) for my @Entity class (used by
hibernate)
- created @Service(ObjectExstendingMyEntity.class). i didn't used the
@Entity class directly to keep the code clean, i'm not sure if this
can be be a problem, but all static methods are working correctly.
I've also tryed to move anything inside the @Entity class but the
error still remain.
- created a CellTable with some column and some editable fields: here
an example of one column updater:
comColumn.setFieldUpdater(new FieldUpdater() {
public void update(int index, LavoratoProxy object, String value) {
LavoratoRequest lavReq = requestFactory.lavoratoRequest();
LavoratoProxy newObject = lavReq.edit(object);
int selectedIndex = comOption.getSelectedIndex();
String commId;
if (selectedIndex >= 0 ){
//Another column
commId = comOption.getValue(selectedIndex);
}
for (CommessaProxy comm : currentList){
//searching into an existing list
if (comm.getId().equals(commId)) {
newObject.setCodiceCommessa(comm);
lavReq.persist().using(newObject).fire(new
Receiver(){
@Override
public void onFailure(ServerFailure
error){
Window.alert("ERROR:
"+error.getMessage());
}
@Override
public void onSuccess(Object response) {
Window.alert
