Flex and Parsley Logging - apache-flex

Question

i'm looking for a possibility to log messages in my flex 4.5 Project. This should cover errormessages in remoteClasses, errorHandler or messages typing by hand.
After reading a lot of webpages, the solution from parslay looks good. i want to switch to this framework anyway.
the benefit is the possibility to configure the logging behavior at runtime. but i don't understand the documentation. perhaps because I'm brandnew in parsley. Also google has no fitting result.
Do you have already did this and it is possible for you to give me a few code snippets.
Thanks a lot
Frank
EDIT:
Because of J_A_X justified criticism, i add my code, because i have partially succeeded.
First we need a config file, because i want to configure the logging behavior in runtime. This is a simple xml-file in the project root.
<?xml version="1.0" encoding="UTF-8"?>
<objects
xmlns="http://www.spicefactory.org/parsley"
xmlns:log="http://www.spicefactory.org/parsley/flex/logging"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.spicefactory.org/parsley
http://www.spicefactory.org/parsley/schema/2.3/parsley-core.xsd
http://www.spicefactory.org/parsley/flex/logging
http://www.spicefactory.org/parsley/schema/2.3/parsley-logging-flex.xsd"
>
<log:target level="info" type="components.SocketTarget">
</log:target>
</objects>
This is my Application:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

<fx:Script>
<![CDATA[
import mx.controls.Label;
import mx.events.FlexEvent;
import mx.logging.Log;
import org.spicefactory.lib.logging.LogContext;
import org.spicefactory.parsley.flex.logging.FlexLoggingXmlSupport;
protected function onAppInitiallize(event:FlexEvent):void
{
FlexLoggingXmlSupport.initialize();
LogContext.getLogger(this);
//Log.getLogger("myCat").info("MyInfo");
}
protected function button1_clickHandler():void
{
Log.getLogger(this.toString()).info("myMessage");
Log.getLogger(this.toString()).fatal("myMessage");
}
]]>
</fx:Script>
<fx:Declarations>
<parsley:ContextBuilder>
<parsley:XmlConfig file="config.xml"/>
</parsley:ContextBuilder>
</fx:Declarations>
<s:Button click="button1_clickHandler()" label="SendLogToParsley" />
</s:Application>
At this point, the logging will work in the console of the flex builder, because parsley uses by default the TraceTarget. Now, i want to send my Logfiles to a socket. I wrote a litte rough SocketTarget.
package de.axurit.components
{
import flash.net.Socket;
import mx.logging.AbstractTarget;
import mx.logging.LogEvent;
import mx.logging.targets.LineFormattedTarget;
public class SocketTarget extends AbstractTarget
{
private var _host:String;
private var _port:int;
private var _socket:Socket;
public function SocketTarget(host:String = "localhost",port:int=8085)
{
_host = host;
_port = port;
_socket = new Socket (host,port);
super();
}
override public function logEvent (event:LogEvent):void
{
trace ("logevent" + event.message);
_socket.writeUTF(event.message + String.fromCharCode(13));
_socket.flush();
}
}
}
In the parsley documentation i can see the comment
The default target type created by this tag is a TraceTarget. You can
explicitly declare other target types:
If i add the type-attribute, i receive a Errormessage "One or more errors in BootstrapProcessor". The same as i received after a typo.
Can you give me some hints, how i can send my logs to a socket destination?

Answer 1

You're creating the socket, but never actually connect it. Plus, if you're going to make a log target, make your class extend trace target and override the log function.
