Struts/Velocity setup confusion

[algol68]

I am new to spring so I am not quite sure how all the pieces fit so here is my problem:

I am writing struts app and I need to be able to use Velocity for views.


my spring config file:

<bean id="velocityEngine" singleton="true" class="org.springframework.ui.velocity.VelocityEng ineFactoryBean">
<property name="velocityPropertiesMap">
<map>
<entry key="resource.loader">
<value>ds, class</value>
</entry>

<entry key="class.resource.loader.class">
<value>org.apache.velocity.runtime.resource.loader .ClasspathResourceLoader</value>
</entry>

<entry key="ds.resource.loader.instance">
<ref bean="templateLoader"/>
</entry>
<entry key="ds.resource.loader.resource.table">
<value>velocity_template</value>
</entry>
<entry key="ds.resource.loader.resource.keycolumn">
<value>name</value>
</entry>
<entry key="ds.resource.loader.resource.templatecolumn">
<value>content</value>
</entry>
<entry key="ds.resource.loader.resource.timestampcolumn">
<value>update_tstamp</value>
</entry>
</map>
</property>
</bean>

<bean id="templateLoader" singleton="true" class="org.apache.velocity.runtime.resource.loader .DataSourceResourceLoader">
<property name="dataSource">
<ref local="dataSource"/>
</property>
</bean>

<bean id="velocityConfigurer" class="org.springframework.web.servlet.view.veloci ty.VelocityConfigurer">
<property name="velocityEngine">
<ref local="velocityEngine" />
</property>
</bean>

Now...should I use VelocityViewServlet(i'll have to configure everything again) or can I use VelocityViewResolver?

<bean id="viewResolver" class="org.springframework.web.servlet.view.veloci ty.VelocityViewResolver">
<property name="suffix">
<value>.vm</value>
</property>
<property name="toolboxConfigLocation">
<value>/WEB-INF/toolbox.xml</value>
</property>
<property name="exposeRequestAttributes">
<value>true</value>
</property>
</bean>

If I use VelocityViewResolver what additional components do I need to configure?

Basically, Struts forward to a view processor. That is, if you want to use Velocity, you should configure VelocityViewServlet in your web.xml
For more information on using/configuring Struts with Spring, please review Chapter 15. Integrating with other web frameworks.

Hope this helps.

I got struts to play nice with spring - my problem is velocity. I already have Velocity Engine configured in spring and I would like to reuse that configuration (see my configs above). If I configure VelocityVewServlet in web.xml I will have to configure another Velocity engine.
