T5.0.7: No service implements the interface org.slf4j.Logger
This used to work, but now it's broken for me in 5.0.6 and 5.0.7. I'm not sure how to debug this. Apparently a proxy is being created for Logger, but when HibernateSessionManagerImpl tries to use it, it can't be realized. Thanks in advance for any help.
Here are the relevant bits of AppModule.java:
import org.slf4j.Logger;
...
public class AppModule {
...
public static void contributeHibernateSessionSource(OrderedConfiguration<HibernateConfigurer> config, Logger log) {
config.add("DatabaseConnectionProperties", new DatabaseConnectionPropertiesHibernateConfigurer(log), "after:Default");
}
...
and here's the stack trace:
Caused by: java.lang.RuntimeException: Exception constructing service 'HibernateSessionSource': Error invoking service builder method org.apache.tapestry.hibernate.HibernateModule.build(Logger, List) (at HibernateModule.java:111) (for service 'HibernateSessionSource'): Error invoking service contribution method com.centricsoftware.pi.services.AppModule.contributeHibernateSessionSource(OrderedConfiguration, Logger): No service implements the interface org.slf4j.Logger.

The situation is that you can inject a Logger when constructing a
service, but you can't inject a Logger when contributing to a service.
Perhaps it would be a good idea to allow the service's Logger to be
injected into contributor methods, with the intention that any logging
related to the service goes to the same logger.

Re: T5.0.7: No service implements the interface org.slf4j.Logger
Posted by Robert Zeigler <ro...@scazdl.org>.
This is a different issue from the threads mentioned. Those threads
are classloader issues, where the slf4j classes can't be found.
In Franz's case, the org.slfj4.Logger interface is properly loaded by
the classloader. The issue is that the ioc container is confusing the
Logger parameter for a service, and trying to fetch an implementation
of Logger from the registry.
I ran into the same issue last night with a 5.0.10 snapshot build.
It's a bit inconsistent, though.
In one of my contribute methods, I inject several services, plus the
Logger. That works fine.
I had another contribute method with several parameters to which I
added a Logger parameter. And that one broke, just like Franz is
seeing, with a "no service implements org.slf4j.Logger" exception.
In my case, I as able to work around the issue. I was doing a bit of
object creation within the contribute method, but I realized I could
let Tapestry autobuild those objects and register them as services.
Instead of injecting the object dependencies into my contribute
method, I was able to inject the objects directly. That worked around
the issue.
You ought to be able to do the same thing. In your service binder
method of your application module, you should be able to:
binder
.bind
(HibernateConfigurer
.class
,DatabaseConnectionProeprtiesHibernateConfigurer
.class).withId("dbconfigurer");
And then instead injecting Logger, you should be able to:
public static void
contributeHibernateSessionSource
(OrderedConfiguration<HibernateConfigurer> config,
@InjectService("dbconfigurer")
HibernateConfigurer dbconfigurer) {
config.add(dbconfigurer,"after:Default");
}
HTH,
Robert

Re: Quick but urgent Tapestry question

In 4.1 this can be done, the solution is no different than the chart
built into the workbench, except that instead of returning an IAsset
that invokes a URL request that generates the chart, the
IEngineService will read and push the content of an external file.

That's odd, I don't understand why it would have worked in 5.0.5! A
Logger should only be available for a service builder method, not for
a contribution method.
