Re: [VOTE] Struts 2.5 BETA1

How to configure that?
Beside the approach I posted earlier I only found the other solution to
throw log4j1 stuff away and create a log4j2 config. Therefore I needed
these 2 jars: log4j-core and log4j-slf4j-impl.
But that caused log messages sent via slf4j-api to appear twice. So more
fiddling is required.

In your case you would have to add these 2 jars:
- log4j-core
- log4j-jcl
And you would need to create a log4j2 config.
The other approach would be to forward log4j2 messages to commons-logging.
But there seems to be no jar that implements that right now.

I had the same dependency. Even before struts 2.5-beta. With that I get
the same error as Greg:
> ERROR StatusLogger Log4j2 could not find a logging implementation.
> Please add log4j-core to the classpath. Using SimpleLogger to log to the
console...
And there were no struts log messages at all.
As you don't get that error it may be specific to the app-server. I'm
bound to WebSphere for this app.

That basically means to re-write logging config for log4j2, which I had
already to do for the approach in my previous post. (the other approach
was just to use log4j2 as logging impl)
Regards and have a nice weekend,

I've just added these to my pom
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
and it works

In case anybody wonders, that was just due to logger additivity:
