Just follow the next three steps and enjoy :

1) SET UP YOUR CONFIG FILE

Add the following code to config/=coldbox.cfc :

coldbox = {
    // Declare the exception handler
    exceptionHandler = "Main.onException",
    onInvalidEvent    = "Main.onPageNotFound"
}
// Replace "Main" by your handler's name

webservices = {
    // Declare the BugLog's webservice
    BugLog = "http://MyBugLogServer/bugLog/listeners/bugLogListenerWS.cfc?wsdl"
}
// Replace "MyBugLogServer" by your server IP/Hostname

settings = {
    // Declare the BugLog email recipient
    bugEmailRecipients = "MyEmail"
}
//Replace "MyEmail" by one or multiple coma separated emails to receive errors by mail if BugLog's webservice is unreacheable

2) SET UP YOUR EXCEPTION HANDLER

// Add the following code to handlers\YourExceptionHandler.cfc where "YourExceptionHandler.cfc" is your exception handler filename
<cffunction name="onException" access="public" output="false" returntype="void">
    <cfargument name="event" type="any">   

    <cfscript>
    //Grab the Exception From the request collection
    var oExceptionBean = event.getValue("ExceptionBean");

    getPlugin(plugin="BugLog",customPlugin=true).logError(oExceptionBean);
    </cfscript>
   
</cffunction>

// replace "YourWebsiteURL" by the URL of your website
<cffunction name="onPageNotFound" access="public" output="false" returntype="void" >
    <cfargument name="event" type="any">
    <cfscript>
    var rc = event.getCollection();
    var url = "http://YourWebsiteURL"   
    var controller = application.cbController;
    var exceptionService = controller.getExceptionService();
    var ExceptionBean = "";

    try {
        $throw(message="The request '#CGI.SCRIPT_NAME#' is invalid",detail="This error is generated when the request doesn't match a valid event",type="404");
    } catch (any e){
        ExceptionBean = exceptionService.ExceptionHandler(e,e.type,e.message);   
        getPlugin("BugLog",true).logError(ExceptionBean,"info");
    }
    </cfscript>
    <cflocation url="#url#" addtoken="false" statusCode="300">
</cffunction>

3) ADD THE PLUGIN

Just drop the BugLog.cfc file into your application plugins directory (/plugins/)
