how to setup the BlazeDS implementation with Log4j

 

1) add slf4j-api-1.5.8.jar,log4j-1.2.15.jar,slf4j-log4j12-1.4.2.jar into your project

 

please make yourself understand the relationship among them.

 

2) produce the following:

 

import org . slf4j . Logger ;  
import org . slf4j . LoggerFactory ;  
 
import flex . messaging . log . AbstractTarget ;  
import flex . messaging . log . LogEvent ;  
 
public class B lazeDSLog4j   extends AbstractTarget {  
    // log4j levels:   OFF - FATAL - ERROR - WARN - INFO - DEBUG - TRACE - ALL  
    // blazeds levels:  NONE - FATAL - ERROR - WARN - INFO - DEBUG - ALL  
 
    @Override  
    public void logEvent ( LogEvent event ) {  
        Logger log = LoggerFactory . getLogger ( event . logger . getCategory ());  
 
        if ( event . level >= LogEvent . ERROR )  
            log . error ( event . message , event . throwable );  
        else if ( event . level >= LogEvent . WARN )  
            log . warn ( event . message , event . throwable );  
        else if ( event . level >= LogEvent . INFO )  
             log . info ( event . message , event . throwable );  
        else if ( event . level >= LogEvent . DEBUG )  
             log . debug ( event . message , event . throwable );  
        else  
             log . trace ( event . message , event . throwable );  
    }  
}  

 

3) modify the configuration in servies-config.xml

 

<services-config> 
    <logging> 
        <target class="BlazeDSLog4j " level="All"> 
    </logging> 
</services-config>
