GWT Remote Logging with Grails GWT Plugin

[confile]

How do I have to setup GWT remote logging with the Grails GWT Plugin.

In my web.xml file I did:

    <servlet>
        <servlet-name>remoteLogging</servlet-name>
        <servlet-class>com.google.gwt.logging.server.RemoteLoggingServiceImpl</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>remoteLogging</servlet-name>
        <url-pattern>/web/remote_logging</url-pattern>
    </servlet-mapping>  

In my gwt.xml file I did:

    <inherits name="com.google.gwt.logging.Logging" />
    <set-property name="gwt.logging.logLevel" value="INFO" />
    <set-property name="gwt.logging.enabled" value="TRUE" />
    <set-property name="gwt.logging.popupHandler" value="DISABLED" />
    <set-property name="gwt.logging.developmentModeHandler" value="ENABLED" />  
    <set-property name="gwt.logging.simpleRemoteHandler" value="ENABLED" />

And somewhere in my GWT Java code I did:

import com.google.gwt.logging.client.SimpleRemoteLogHandler;
import java.util.logging.Level;
import java.util.logging.LogRecord;

SimpleRemoteLogHandler remoteLog = new SimpleRemoteLogHandler();
remoteLog.publish(new LogRecord(Level.INFO, “log message”));

But, I got the following error:

06:03:00.592 [ERROR] [web] Sun Feb 09 06:03:00 CET 2014 WireActivityLogger
SEVERE: Remote logging failed: 
com.google.gwt.user.client.rpc.InvocationException:

Do you have any idea how to fix that?
