Re: Wicket + Guice + Warp-persist + Hibernate
How does the code that are using it look like? Are you using detachable
models etc?
2009/10/6 Jeffrey Schneller jeffrey.schnel...@envisa.com
So I took the plunge and tried to implement Guice + Warp Persist to
solve my lazy loading issues. I know I may not have it all figured out
with regards to lazy loading but I can't even get simple data access to
work now. Sorry for all the questions and issues. Can anyone provide
some insight on what is wrong or what I am missing. The Hibernate
configuration succeeds in the getModule() method.
Thanks.
Code is below:
My Web Application
public class WicketApplication extends WebApplication {
private PersistenceService service;
public WicketApplication() {
}
@Override
public Class? extends Page getHomePage() {
return Home.class;
}
@Override
public Session newSession(Request request, Response
response) {
return new MySession(request);
}
@Override
protected void init() {
Injector injector =
Guice.createInjector(PersistenceService.usingHibernate()
.across(UnitOfWork.REQUEST).transactedWith(
TransactionStrategy.LOCAL).buildModule(),
getModule());
addComponentInstantiationListener(new
GuiceComponentInjector(this, injector));
service =
injector.getInstance(PersistenceService.class);
service.start();
injector.injectMembers(this);
}
private Module getModule() {
return new Module() {
public void configure(Binder binder) {
// default values from development
String connectionUrl = the url;
String username = the username;
String password = the password;
try {
InitialContext context =
new InitialContext();
connectionUrl = (String)
context.lookup(java:comp/env/hibernate.connection.url);
username = (String)
context.lookup(java:comp/env/hibernate.connection.username);
password = (String)
context.lookup(java:comp/env/hibernate.connection.password);
} catch (NamingException e1) {
// TODO Auto-generated
catch block
e1.printStackTrace();
}
// annotation and xml
final AnnotationConfiguration config =
new AnnotationConfiguration().configure();
config.setProperty(hibernate.connection.url, connectionUrl);
config.setProperty(hibernate.connection.username, username);
config.setProperty(hibernate.connection.password, password);
config.setProperty(hibernate.current_session_context_class,
managed);
binder.bind(Configuration.class).toInstance(config);
}
};
}
}

RE: Wicket + Guice + Warp-persist + Hibernate
I haven't even got to the detachable models part of it yet. A simple
query to the db does not work as it does not have the session injected.

Re: Wicket + Guice + Warp-persist + Hibernate
Hmm seems like your Guice arent booted? Are you using the Guice integration
from wicket as well? Does service.start() etc give an exception etc?
