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.xmlwe'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.
