Re: Request implementation couldn't be found.
To handle server-side errors I have defined an custom servlet extending the default RequestFactoryServlet and passed a custom exception handler in the constructor.. That has shown me a real causes of my problem located on the server side. Good tutorial to define a custom servlet can be found here http://cleancodematters.wordpress.com/2011/05/29/improved-exceptionhandling-with-gwts-requestfactory/#more-74 . I hope it will also help others. My problem was JPA and particularly @GeneratedValue annotation for Id because that uses a native generating policy and datanucleus is not supporting it. So i had to define another one . -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Request implementation couldn't be found.
As RF complains: you declare a findRate() InstanceRequestRateProxy,Void on the RateRequest with no corresponding findRate() method on Rate. RF find the static findRate(Long) method (same name) which is required in the absence of a Locator, which it lists as possible match (same name) in the error message. In other words, it's exactly what I told you earlier: your method findRate in the RateRequest has no corresponding method findRate in the server-side rate class (which by the way, is exactly what the error message says too) -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Request implementation couldn't be found.
The thing is that it happens when i try to fire a request with any of the methodes implemented on the entity side. Console is always saying [ERROR] Could not find matching method in synlogistics.ratesexchange.server.domain.Rate. Possible matches: synlogistics.ratesexchange.server.domain.Rate findRate(java.lang.Long ) I will definitely try to configure it manually, but I will be happy to get it working also on the normal way. Could there be any other reasons why it is not working? Thank you for your help and for your blog also!

When starting my application it fails on firing the request. Debug mode says RatesRequestImpl.findrates(int a, int b) source couldn't be found. Where findrates is one of my methods.

Re: Request implementation couldn't be found.
The problem is it definitely has one in the Rate class (my Entity
class, all annotations set and checked everywhere)
Defined as :
@SuppressWarnings(unchecked)
public static ListRate findRates(int first, int max){
EntityManager em = EMF.get().createEntityManager();
try{
Query query = em.createQuery(select o from Rate o);
query.setFirstResult(first);
query.setMaxResults(max);
ListRate list = query.getResultList();
list.size();
return list;
}
finally {
em.close();
}
}
