I am using joran Configurator to load  muy logback.xml. I do this:

   LoggerContext context = (LoggerContext)
LoggerFactory.getILoggerFactory();
                JoranConfigurator configurator = new JoranConfigurator();                      
                configurator.setContext(context);
                context.reset();
                if (logbackfile != null) {
                    InputStream fis =
                       
getServletContext().getResourceAsStream(logbackfile);               
                    configurator.doConfigure(fis);
                }

In my integrated WebLogic Server it works perfect but when i deploy it in a
production server it can find my classes that i configured in logback.xml as
a evaluator. You can see on the end.

It looks  LoggerContext dont load class correctly. I have try to use
ch.qos.logback.core.util.Loader.loadClass("util.log.LogSMTPEvaluator") and
works perfectly but when i use
ch.qos.logback.core.util.Loader.loadClass("util.log.LogSMTPEvaluator",context)
it doenst works. 

¿any idea please?


----------------------------------------------
I generated a smtp appender with my evaluator. 
in logBack.xml I have 

 <appender name="Email" 
            class="ch.qos.logback.classic.net.SMTPAppender"> 
    <evaluator class="util.log.LogSMTPEvaluator"/> 
    <smtpHost>${correo.name.direccionSMTP}</smtpHost> 
    <to>${correo.name.to}</to> 
    <from>${correo.name.from}</from> 
    <username>${correo.name.usuario}</username> 
    <password>${correo.name.clave}</password> 
    <layout class="ch.qos.logback.classic.html.HTMLLayout"> 
      <pattern>%d{yyyy-MM-dd HH:mm:ss}==> %m%n</pattern> 
    </layout> 
  </appender> 

When I deploy in integrated Weblogic Server with Jdeveloper11 it works fine.
But, when i generated ear and  deploy over my Weblogic Server i get: 
12:32:57,830 |-ERROR in
ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Could not create
