Apache Tiles 3.0 - Locally Save and Reference DTD - tiles

Question

We're using Apache Tiles 3.0.
In our Apache Tiles-Def file, we occasionally have problems with this DTD reference, maybe because the site is unreliable. There are I/O errors "Reading Definitions" occasionally:
<!DOCTYPE tiles-definitions PUBLIC "-//Apache Software Foundation//DTD Tiles Configuration 3.0//EN"
"http://tiles.apache.org/dtds/tiles-config_3_0.dtd">
The idea came up to save the DTD in the project. We dropped the DTD into /WEB-INF/classes, but it can't be found:
1) just "tiles-config_3_0.dtd":
Error: C:\Eclipse\LunaSR2\tiles-config_3_0.dtd not found
2) "/WEB-INF/classes/tiles-config_3_0.dtd":
java.io.FileNotFoundException: \WEB-INF\classes\tiles-config_3_0.dtd (The system cannot find the path specified)

Answer 1

1 ) In WEB-INF folder need to place the tiles-config_3_0.dtd
WEB-INF\tiles-config_3_0.dtd
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE tiles-definitions PUBLIC
"-//Apache Software Foundation//DTD Tiles Configuration 3.0//EN"
"http://tiles.apache.org/dtds/tiles-config_3_0.dtd">
2 ) Add the below mentioned dependencies in pom.xml
<dependency>
<groupId>org.apache.tiles</groupId>
<artifactId>tiles-core</artifactId>
<version>3.0.8</version>
</dependency>
<dependency>
<groupId>org.apache.tiles</groupId>
<artifactId>tiles-api</artifactId>
<version>3.0.8</version>
</dependency>
<dependency>
<groupId>org.apache.tiles</groupId>
<artifactId>tiles-servlet</artifactId>
<version>3.0.8</version>
</dependency>
<dependency>
<groupId>org.apache.tiles</groupId>
<artifactId>tiles-template</artifactId>
<version>3.0.8</version>
</dependency>
<dependency>
<groupId>org.apache.tiles</groupId>
<artifactId>tiles-el</artifactId>
<version>3.0.8</version>
</dependency>
</dependency>
<dependency>
<groupId>org.apache.tiles</groupId>
<artifactId>tiles-master</artifactId>
<version>6</version> or
<version>7</version>
</dependency>
3 ) Provide the concern classes in Dispatch-servlet.xml
<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="tilesConfigurerId"
class="org.springframework.web.servlet.view.tiles3.TilesConfigurer">
<property name="definitions">
<list>
<value>/WEB-INF/tiles-config_3_0.dtd</value>
</list>
</property>
</bean>
