Re: DWR 2 and Spring 2

Hi,

This is actually a bit of a gotcha I think. Anyway, by default Springs SimpleUrlHandlerMapping sets alwaysUseFullPath to false and in our web.xml we've mapped /dwr/* to the spring dispatcher servlet (someone please correct me if I'm wrong). So the pattern that gets passed to SimpleUrlHandlerMapping by spring is the bit _after_ /dwr. By making the dwrController match everything request that falls through the mappings you've defined you're catching it but you might not want that in general eh?

Anyway, if you set alwaysUseFullPath to false SimpleUrlHandlerMapping you can do something like this:

    <bean id="urlHandlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping ">
        <property name="alwaysUseFullPath" value="true"></property>
        <property name="mappings">
            <props>
...
                <prop key="/dwr/**/*">dwrController</prop>
          </props>
etc

The way I've set it up in spring is to have two SimpleUrlHandlingMapping instances declared. One for regular spring controllers and another for dwr like so:

    <bean id="urlHandlerMapping" class=" org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>
                <prop key="/blog/captchaImage.do"> commons.captchaController</prop>
                <prop key="/blog/categoryList.do">weblog.categoriesListController</prop>
...
            </props>
        </property>
    </bean>


    <bean id="dwrHandlerMappings" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="order" value="1" />
        <property name="alwaysUseFullPath" value="true"></property>
        <property name="mappings">
            <props>
                <prop key="/dwr/**/*">dwrController</prop>
            </props>
        </property>
    </bean>

Let me know if that helps.
