Cant able to appy <pattern> and <Layout> in <encoder> of logback.xml


I am trying to create custom layout in Logback, using the link,

http://stackoverflow.com/questions/14168684/creating-a-custom-layout-in-logback

and i am successful in creating log file.

The problem is when I apply "pattern" tag in encoder tag of logback.xml like this,

Logback.xml

==========

<appender name="appLogFileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>C:/tmp.log</fileNamePattern>
        </rollingPolicy>

<encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
             <pattern> %d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n </pattern>
             <layout class="com.dces.util.LoggingConsoleLayout" />
        </encoder>
    </appender>

it is not applied on log file, which is created, and I am getting content without date&time AS BELOW.

-- [ERROR]main.java.com.srccodes.log.LogbackHello - Welcome to the HelloWorld example of Logback. 

-- [ERROR]main.java.com.srccodes.log.LogbackHello - Dummy error message.

Actually if I remove class="ch.qos.logback.core.encoder.LayoutWrappingEncoder" in encoder tag ,pattern is working, but then my custom layout is not working.

I want to apply pattern tag as well as custom layout tag on encoder tag.Is it is possible?


LoggingConsoleLayout.xml - My Cuatom Layout

=====================================

public class LoggingConsoleLayout extends LayoutBase<ILoggingEvent>{

@Override

public String doLayout(ILoggingEvent event) {

StringBuffer sbuf = null;

try

{

sbuf = new StringBuffer(128);

sbuf.append("-- ");

sbuf.append("[");

sbuf.append(event.getLevel());

sbuf.append("]");

sbuf.append(event.getLoggerName());

sbuf.append(" - ");

sbuf.append(encodeData(event.getFormattedMessage()));

//here i am encoding my log messages and which is important for me

sbuf.append(CoreConstants.LINE_SEPARATOR);

}

catch(Exception e)

{

e.printStackTrace();

}

return sbuf.toString();

}

}

when I tried this,


<encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">

<layout class="com.dces.util.LoggingConsoleLayout" > 

  <Pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</Pattern>

  </layout>

</encoder>


I got ERROR in ch.qos.logback.core.joran.spi.Interpreter@17:17 - no applicable action for [Pattern], current ElementPath  is [[configuration][appender][encoder][layout][Pattern]]

And my pattern is not applied to my layout...

Is there is any possibility to have both layout and pattern tags in encoder tag?
