How to switch between 2 message bundles?

i'm having some issues handling the i18n of my webapp.
Is it possible through Spring to found a message in a MessageSource if it's not found in the other?
This is my Spring configuration
<bean id="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="xxMessage" />
</bean>
<bean id="localeResolver"
class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
<property name="defaultLocale" value="en" />
</bean>
Example:
if the key is "login.user" and the locale is "en" the app shows the value in my xx_en.properties if exists, BUT i want to search in the other file (xx_es.properties) if the key doesn't exists.
Is that possible?
P.S: sorry for my english :D
Thanks in advance!

I think you need to have interceptor configuration in your spring configuration
<interceptors>
<beans:bean
class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<beans:property name="paramName" value="locale" />
</beans:bean>
</interceptors>

Thanks, for your answer #DDK i've already managed to resolve the problem :D
Solution below.
Define chained message sources, provided by the interface HierarchicalMessageSource.
For example, if you have your i18n files
baseMessages.properties
and
messages.properties
you could chain them as
<bean id="baseMessageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="baseMessages" />
</bean>
<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="messages" />
<property name="parentMessageSource" ref="baseMessageSource" />
</bean>

Thymeleaf - Error resolving template "email-inlineimage.html"

So, I see all answer this problem in Stackoverflow, but not be of any help to me.
(
SpringMVC+Thymeleaf ,error message is : template might not exist or might not be accessible by any of the configured Template Resolvers

I can't spot error in your servlet-context.xml so problem must be buried somewhere else (are you sure you have template file on classpath exactly at mail/email-inlineimage.html?). I'm providing working example as whole project (since it's overkill to paste everything to code samples here) which you can import to STS and run.

Multiple Resource Bundle in JSP message code

I am using Spring MVC 3. I have message bundles in following format :
message_en_US.properties
message_en.properties
message_USA.properties
In my JSP I am using :
Now, the order of finding the values should be en_US, then en then USA property files.
how can i customize this ?

You should use configuration below. So, if you want to set default language you can use the second one.
In my src/main/resources I have mymessages_en_US.properties and mymessages_es_ES.properties
<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="basenames">
<array>
<value>classpath:mymessages</value>
</array>
</property>
<property name="defaultEncoding" value="UTF-8" />
<property name="cacheSeconds" value="0" />
</bean>
<bean id="localeResolver"
class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
<property name="defaultLocale" value="es_ES" />
</bean>

Spring ReloadableResourceBundleMessageSource VS ResourceBundleMessageSource

Hi I am trying to configure message sources in my Spring MVC web application .
I have currently got it running with ReloadableResourceBundleMessageSource but I am not able to get it running with ResourceBundleMessageSource . I would have preferred to use ResourceBundleMessageSource because I dont need the Reload capability and ResourceBundleMessageSource is slightly more efficient.
in my rootApplicationContext , I have defined the beans as follows.
<bean id="messageSource"
class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="basename" value="/resources/locale/messages" />
<property name="defaultEncoding" value="UTF-8"/>
</bean>
<bean id="localeChangeInterceptor"
class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="lang" />
</bean>
<bean id="localeResolver"
class="org.springframework.web.servlet.i18n.SessionLocaleResolver" />
<bean id="handlerMapping"
class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="interceptors">
<ref bean="localeChangeInterceptor" />
</property>
</bean>
This works FINE ..
But as soon as I change to
<bean id="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="/resources/locale/messages" />
<property name="defaultEncoding" value="UTF-8"/>
</bean>
The application breaks with the exception :
12:35:57,433 ERROR
[org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/SpringJAXWS].[jsp]]

HELP !
The Entire project code is available at GITHUB
https://github.com/localghost8080/JaxWS
Here is the entire stack trace for all who are interested.
https://github.com/localghost8080/JaxWS/blob/master/ResourceBundleException.txt

ResourceBundleMessageSource uses a different format for passing basename values
<bean id="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="resources.locale.messages" />
<property name="defaultEncoding" value="UTF-8"/>

Spring does not using sources in default locale

I've changed default locale in spring configuration, but spring always uses messages_en.properties instead of messages.properties.It seems that Spring is ignoring my choice of locale.
defined locases:
messages.properties
messages_en.properties
Spring configuration:
application-context.xml
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
<property name="defaultLocale" value="cs"/>
</bean>
<bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="lang" />
</bean>
<bean name="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basenames">
<list>
<value>messages</value>
</list>
</property>
<property name="defaultEncoding" value="UTF-8" />
</bean>
servlet-context.xml
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/**" />
<exclude-mapping path="/admin/**"/>
<exclude-mapping path="/image/**"/>
<exclude-mapping path="/ajax/**"/>
<beans:bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" />
</mvc:interceptor>
</mvc:interceptors>
In JSP page
<spring:message code="csn.terminology.csnId" />
<p>Current Locale : ${pageContext.response.locale}</p>
<!-- output is 'cs', but messages are from messages_en.properties file -->
In project is used Spring Framework 3.2.4
Thank you in advance for your help.

if it's the complete configuration then you forgot to add the locale resolver
You can add a SessionLocaleResolver like this and set the default locale property
<bean id="localeResolver"
class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
<property name="defaultLocale" value="en"></property>
</bean>

When locale is null, AbstractMessageSource calls Locale.getDefault()
So you should set set default locale as follow:
#Bean
public MessageSource messageSource() {
ResourceBundleMessageSource messageSource=new ResourceBundleMessageSource();
messageSource.setBasename("messages");
// SET DEFAULT LOCALE AS WELL
Locale.setDefault(Locale.US);
return messageSource;
}
