tiles with spring : getting error - java.lang.Clas

Question

I am new to spring and trying to use tiles with Spring. but getting above error. i am using maven in my project. i tried changing versions also, but no use. following are contents of project:

pom.xml

  <!-- Apache Tiles -->
    <dependency>
        <groupId>org.apache.tiles</groupId>
        <artifactId>tiles-core</artifactId>
        <version>3.0.5</version>
    </dependency>

    <dependency>
        <groupId>org.apache.tiles</groupId>
        <artifactId>tiles-jsp</artifactId>
        <version>3.0.5</version>
    </dependency>

     <dependency>
        <groupId>org.apache.tiles</groupId>
        <artifactId>tiles-api</artifactId>
        <version>3.0.5</version>
    </dependency>
     <dependency>
        <groupId>org.apache.tiles</groupId>
        <artifactId>tiles-servlet</artifactId>
        <version>3.0.5</version>
    </dependency>
     <dependency>
        <groupId>org.apache.tiles</groupId>
        <artifactId>tiles-template</artifactId>
        <version>3.0.5</version>
    </dependency>

servlet-context.xml

  <!-- for Tiles -->
<bean class="org.springframework.web.servlet.view.UrlBasedViewResolver" id="viewResolver">  
    <property name="viewClass" value="org.springframework.web.servlet.view.tiles2.TilesView"/>            
</bean>

<bean class="org.springframework.web.servlet.view.tiles2.TilesConfigurer" id="tilesConfigurer">  
    <property name="definitions" value="/WEB-INF/tiles-definitions.xml" />           
</bean>

tiles-definitions.xml

  <?xml version="1.0" encoding="UTF-8"?>
<tiles-definitions>  
    <definition name="base.definition" template="/WEB-INF/views/tilesMainTemplate.jsp">  
        <put-attribute name="title" value=""></put-attribute>  
        <put-attribute name="header" value="/WEB-INF/views/header.jsp"></put-attribute>  
        <put-attribute name="menu" value="/WEB-INF/views/home.jsp"></put-attribute>  
        <put-attribute name="body" value=""></put-attribute>  
        <put-attribute name="footer" value="/WEB-INF/views/footer.jsp"></put-attribute>  
    </definition>  

    <definition extends="base.definition" name="saveAd">  
        <put-attribute name="title" value="Post your free Ad"></put-attribute>  
        <put-attribute name="body" value="/WEB-INF/views/adSave.jsp"></put-attribute>  
    </definition>  


</tiles-definitions>  

then there are tilesMainTemplate, header and footer jsp's which i dont think have any issues. any help in this regard will be highly appreciated, Thanks in advance.

Answer 1

In your servlet-context.xml you are using the tiles2 spring-tiles integration classes.

Use instead the classes found under org.springframework.web.servlet.view.tiles3

Answer 2

Finally it worked ! I replaced tiles2 by tiles3 as correctly pointed out by mck and added following line to tiles-definitions.xml

<!DOCTYPE tiles-definitions PUBLIC
  "-//Apache Software Foundation//DTD Tiles Configuration 3.0//EN" 
  "http://tiles.apache.org/dtds/tiles-config_3_0.dtd">

Answer 3

Using:

import org.springframework.web.servlet.view.tiles3.TilesView;

Not:

import org.springframework.web.servlet.view.tiles2.TilesView;

Answer 4

use this code if your are using version 3 . based on the version your are using should configure the tiles.
<bean id="viewResolver"
        class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass">
            <value>
                org.springframework.web.servlet.view.tiles3.TilesView
            </value>
        </property>
    </bean>
    <bean id="tilesConfigurer"
        class="org.springframework.web.servlet.view.tiles3.TilesConfigurer">
        <property name="definitions">
            <list>
                <value>/WEB-INF/estudo-tiles-servlet.xml</value>
            </list>
        </property>
    </bean>
