Template dispatchers allow different presentation technologies to be used for composing pages that define the look and feel of your blog. The dispatcher handles loading of page templates and making available certain objects for you to use in your templates. blojsom's default installation comes with two different dispatchers, one for using JavaServer Pages (JSP) and one for using Velocity.

Configuring Dispatchers

Dispatchers are configured and referenced according to template suffix in the /WEB-INF/classes/blojsom.xml file. Accordingly, the bean ID for dispatchers must correspond to the suffix for templates that are to be served by a particular dispatcher. For example, in the following case, vm will serve Velocity templates:

<bean id="vm" class="org.blojsom.dispatcher.velocity.VelocityDispatcher" init-method="init">
        <property name="velocityProperties">
            <ref bean="defaultVelocityProperties"/>
        </property>
        <property name="blojsomProperties">
            <ref bean="defaultProperties"/>
        </property>
        <property name="servletConfig">
            <ref bean="servletConfigFactoryBean"/>
        </property>
    </bean>
