Spring 3.1.1 java based configuration issue of FreeMarkerConfigurer

[Fatla]

Hello,
I have been tring to use the FreeMarker as a view resolver.

When I debug it fires an exception at:

FreeMarkerConfigurer configurer = new FreeMarkerConfigurer();

the exception states:

"java.lang.NoClassDefFoundError: freemarker/cache/TemplateLoader"

I have used :

  @Bean
    public ViewResolver viewResolver() {
        UrlBasedViewResolver viewResolver = new UrlBasedViewResolver();
        viewResolver.setViewClass(FreeMarkerView.class);
        return viewResolver;
    }

    @Bean
    public FreeMarkerConfigurer freeMarkerConfigurer() {
        FreeMarkerConfigurer configurer = new FreeMarkerConfigurer();
        configurer.setTemplateLoaderPath(
                "/WEB-INF/views/**/freemarker.xml");
        return configurer;
    }

It looks like Freemarker is not in your runtime classpath.

Your first post makes me look goofy ...just kidding
Yes I was missing to add the dependecy at the maven file.

I am now facing "javax.servlet.ServletException".
However, I have added the freemarker.xml and adjusted my controller to return the freemarker view.

Freemarker.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://www.springframework.org/schema/beans"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">    

    <!-- freemarker config -->
    <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
      <property name="templateLoaderPath" value="/WEB-INF/freemarker/"/>
      <property name="freemarkerSettings">
          <props>
              <prop key="number_format">0.######</prop>
          </props>
      </property>
      <property name="freemarkerVariables">
        <map>
          <entry key="xml_escape" value-ref="fmXmlEscape"/>
        </map>
      </property>
    </bean>
  
    <bean id="fmXmlEscape" class="freemarker.template.utility.XmlEscape"/>
    

    <!--

      View resolvers can also be configured with ResourceBundles or XML files. If you need
      different view resolving based on Locale, you have to use the resource bundle resolver.

    -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
        <property name="cache" value="true"/>
        <property name="prefix" value=""/>
        <property name="suffix" value=".ftl"/>
    </bean>

</beans>

Controller :

	@RequestMapping(value="/", method=RequestMethod.GET)
	public ModelAndView home(Principal user) {
        return new ModelAndView("/welcome");
	}

The "welcome.ftl" is under WEB-INF/freemarker directory.

The exception I get :

javax.servlet.ServletException: Could not resolve view with name '/welcome' in servlet with name 'appServlet'
	org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1139)
	org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:927)
	org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:827)
	org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:882)
	org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:778)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:621)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:722)

I ran your example through Heatlamp [1]. It looks like Spring is appending the "ftl" extension onto your view name. Do you see the double "ftl" extensions?

When I return new ModelAndView("welcome"), without the "ftl" extension, it works for me.

Frankly, I have tried several trials such as removing the postfix ".ftl" from freemarker.xml ,use "return new ModelAndView("/welcome")" ,etc. in order to remove that .ftl duplication.
However,I still have the same issue.

This works for me:

return new ModelAndView("welcome");

How are you running your web application? Are you building a WAR and running it in Tomcat, or something similar?

Exactly,I am using Tomcat7 as an application server and I deploy the war over it.

You are using Maven to build the WAR?

You should look in the WAR and make sure that your template file is being packaged into the WAR in the WEB-INF/freemarker directory.

Also, did you properly configure your web.xml?

<servlet>
<servlet-name>yourapp</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherSe rvlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>yourapp</servlet-name>
<url-pattern>/yourapp/*</url-pattern>
</servlet-mapping>

Then, under WEB-INF, you'll need a "yourservlet-servlet.xml" file that has your Spring MVC configuration.
