Re: Strange ClassNotFoundException: org.slf4j.Logger

2009-01-16 Thread Ulrich Stärk 

Found the problem:
http://docs.codehaus.org/display/JETTY/Classloading

By default Jetty hides org.slf4j.* from webapp context classloaders, therefore the Form component 
can't see it. This can be fine-tuned by calling 
org.mortbay.jetty.webapp.WebAppContext.setServerClasses(String[]) which the run-jetty-run plugin 
isn't doing. So there is no chance to get this running without modifying the run-jetty-run plugin. 
I'll now try to go back to the JettyLauncher (http://jettylauncher.sourceforge.net/) plugin.


HTH,

Uli

 Hi!
 
 I'm having a very strange exception when trying to run a T5
 application (www.arsmachina.com.br/project/example):
 Error obtaining injected value for field
 org.apache.tapestry5.corelib.components.Form.logger:
 java.lang.ClassNotFoundException: org.slf4j.Logger
 It seems to be a Tapestry classloading issue, as slf4j-api *is* in the
 classpath.
 
 At my home, when running from JettyLauncher (modified to run under
 Java 6), runs OK. Under Run-Jetty-Run, the exception is thrown.
 Running an embedded Jetty at my home, ok, at my work, exception
 raised.
 
 Thanks in advance.

 Have you tried setting parentLoaderPriority?

Hi! Thanks for your answer, but it didn't work. That wiki page talks
about @Inject'ng a Logger, but in my case the problem happens when
instantiating (or getting) a Logger for a Form component. All other
pages work.

I assume slf4j is on the classpath twice...
