Ben,
Use the VelocityLayoutServlet in your web.xml.
Actually, if it were only Velocity than that would be the solution. But
since you have
Spring here is the setup:
/WEB-INF/applicationContext.xml
----------------------------------------------------------------------------------------------------------
<beans>
<bean id="velocityConfigurer"
class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
<property name="resourceLoaderPath" value="/"/>
<property name="configLocation"
value="/WEB-INF/velocity.properties"/>
</bean>
</beans>
----------------------------------------------------------------------------------------------------------
/WEB-INF/abc-servlet.xml
----------------------------------------------------------------------------------------------------------
<beans>
<bean id="viewResolver"
class="org.springframework.web.servlet.view.velocity.VelocityLayoutViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.velocity.VelocityLayoutView"/>
<property name="cache" value="true"/>
<property name="prefix" value=""/>
<property name="suffix" value=".vm"/>
<property name="exposeRequestAttributes" value="true"/>
<property name="exposeSessionAttributes" value="true"/>
<property name="exposeSpringMacroHelpers" value="true"/>
<property name="layoutUrl" value="/layout/default_layout.vm"/>
<property name="toolboxConfigLocation"
value="/WEB-INF/toolbox.xml"/>
</bean>
</beans>
----------------------------------------------------------------------------------------------------------
/WEB-INF/velocity.properties (include this anywhere)
----------------------------------------------------------------------------------------------------------
#----------------------------------------------------------------------------
# LAYOUT SERVLET MANAGEMENT
#----------------------------------------------------------------------------
# Allows for screens to be used for layout
#----------------------------------------------------------------------------
# Filepath for error template, relative to web application root directory
tools.view.servlet.error.template = /layout/layout_error.vm
# Directory for layout templates, relative to web application root directory
tools.view.servlet.layout.directory = /layout/
# Filepath of the default layout template
# relative to the layout directory
# NOT relative to the root directory of the webapp!
tools.view.servlet.layout.default.template = default_layout.vm
----------------------------------------------------------------------------------------------------------
/layout/default_layout.vm
----------------------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml"; lang="en" xml:lang="en">
#parse( "/includes/header.vm" )
<body>
#parse( "/includes/navigation.vm" )
$!{screen_content}
#parse( "/includes/footer.vm" )
</body>
</html>
----------------------------------------------------------------------------------------------------------
The default_layout.vm is a wrapper file.
The call goes like so:
- home.htm -> HomeController
- HomeController -> return new ModelAndView( "/home.vm" )
- /home.vm -> set any variables
- VelocityLayoutViewResolver -> wrap home.vm with default_layout.vm
- show page
Hopefully this was all the information you needed to get going. I've
been using this setup for years.
