Hi Thomas,
First, I want to say that your examples and blogs have helped us a lot over
the last year! Thanks!
Secondly, thanks for the super quick reply!
I added the sources generation to the POMs for the Shared, Persistence and
Services projects, and fixed the ".class" issues. However, we are still
getting issues with GWT not being able to find classes/sources... they (at
the moment) seem to be around classes specified via @ExtraTypes which we
have specified in our IAppRequestFactory interface.
eg:
@ExtraTypes({
IAlertProxy.class, IAlertOptionsProxy.class, IAlertTypeProxy.class
})
public interface IOris4RequestFactory extends RequestFactory
{
IAlertRequest alertRequest();
...
}
The specific error is:
Resolving com.mycompany.client.IAppRequestFactory
Found type 'com.mycompany.client.IApp4RequestFactory'
[ERROR] Annotation error: cannot resolve com.mycompany.
client.alerts.proxy.IAlertProxy
java.lang.ClassNotFoundException: com.mycompany.
client.alerts.proxy.IAlertProxy
...
[ERROR] Annotation error: expected class java.lang.Class, got null
It then eventually down the list starts complaining about the Adapters
Resolving com.mycompany.client.alerts.proxy.IAlertProxy
Found type 'com.mycompany.client.alerts.proxy.IAlertProxy'
[ERROR] Annotation error: cannot resolve com.mycompany
.adapter.alert.AlertGwtAdapter
java.lang.ClassNotFoundException: com.mycompany
.adapter.alert.AlertGwtAdapter
The proxy classes are specified in the main client project, and the adapter
classes are in the same project, but outside the client package (referenced
via <source path="adapter" />)
Sorry to bother you again about this, but its had us stuck for a while now.
