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:

Does anyone know how to fix it?
