Well thanks, that was my mistake !
Although now I tried calling the logger in a method called in the
contribute registry startup static method and still tapestry didn't resolve
it:
public class *AppModule* {
@Inject
private IMy my;
public static void bind(ServiceBinder binder) {
binder.bind(IMy.class, My.class);
}
public void contributeRegistryStartup(OrderedConfiguration<Runnable>
configuration, final Logger log) {
my.a();
}
}
package com.t5logging.services;
import javax.inject.Inject;
import org.slf4j.Logger;
public class My implements IMy {
@Inject
private Logger log;
public My() {
}
public void a() {
System.out.println(log);
log.info("Logging again");
}
}
This still throws a service not implemented exception:
