Question

spring-servlet.xml setting up theme beans:

<bean id="themeSource"
class="org.springframework.ui.context.support.ResourceBundleThemeSource">
    <property name="basenamePrefix" value="theme-" />  // also tried WEB-INF.resources.theme- and WEB-INF/resources/theme- here, same problem
</bean>

<bean id="themeChangeInterceptor"
    class="org.springframework.web.servlet.theme.ThemeChangeInterceptor">
    <property name="paramName" value="theme" />
</bean>

<bean id="themeResolver"
    class="org.springframework.web.servlet.theme.CookieThemeResolver">
    <property name="defaultThemeName" value="default" />
</bean>

    <bean id="handlerMapping"
    class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
    <property name="interceptors">
        <list>
            <ref bean="localeChangeInterceptor" />
            <ref bean="themeChangeInterceptor" />
        </list>
    </property>
</bean>

under WEB-INF/resources, where are 3 theme files:

1. theme-black.properties
2. theme-blue.properties
3. theme-default.properties

each file contain this accordingly:

css=themes/black.css
css=themes/blue.css
css=themes/default.css

i have folder WEB-INF/themes , which contains 3 of these css files, i think the content of css isn’t important here.

now error i run into is :

javax.servlet.ServletException: javax.servlet.jsp.JspTagException: Theme 'default': No message found under code 'css' for locale 'en'.

so basically it just can’t find the css value for themes, which means it can’t find the properties file…

what I am doing wrong? feel free to ask questions

You should try to put theme properties into classpath (as is written in docs). Classpath is not /WEB-INF folder. See this question for clarity.

By default the delegate will be a
org.springframework.ui.context.support.ResourceBundleThemeSource that
loads properties files from the root of the classpath.
