[appengine-java] Fetch groups

2010-01-28 Thread KasperDK 
I'm planning to use fetch groups in my java-app hosted on google app
engine. I can't seem to find much about fetch groups in the java app
engine documentation, so my question is if google app engine has
implemented fetch groups as defined in JSR-000243 Java Data Objects
2.2 Maintenance Release 2 ? If not, then where can I read a spec about
this issue ?

Also, please point me to document(s) / blog(s) containing the
technical road map for the GAE.

Cheers,

:-) Kasper

[appengine-java] GUICE injection and access denied (java.lang.RuntimePermission modifyThreadGroup)

2010-06-11 Thread KasperDK 
Hi,

I'm trying to do this;

public class PostalServiceImpl extends RemoteServiceServlet implements
PostalService {
private static final Logger log =
Logger.getLogger(PostalServiceImpl.class.getName());

@Inject
private PostalManager postalManager;

public PostalServiceImpl() {
Injector injector = Guice.createInjector(new 
NetGazelleModule());

injector.injectMembers(this);
}

public String getCity(String postal) {
log.info("PostalServiceImpl.getCity(" + postal + ")");

if (postalManager == null) {
log.severe("PostalServiceImpl.getCity: postalManager is 
null !");
}

return postalManager.getCity(postal);
}

...


But I get the following exception;
