dwr & SpringMVC

  Asked By: Thelma    Date: Mar 19    Category: Java    Views: 1460
  

I'm using spring MVC (spring version 1.2.1) , i want to use dwr(1.4.1) in my application. I've just configured my application as :


web.xml
<servlet>
<servlet-name>dwr-invoker</servlet-name>
<display-name>DWR Servlet</display-name>
<servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>true</param-value>
</init-param>
</servlet>

<servlet>
<servlet-name>mainServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>


<servlet-mapping>
<servlet-name>mainServlet</servlet-name>
<url-pattern>dwr/*</url-pattern>
</servlet-mapping>



------------------------------------------------------------------------------------------
applicationContext.xml

<bean id="stateDAO" class="com.realdevelopment.videonary.dao.specific.StateDAO">
<property name="sessionFactory">
<ref bean="TECSSessionFactory"/>
</property>
</bean>



<bean id="ajaxUtils" class="com.realdevelopment.videonary.web.utils.AjaxUtils">
<property name="stateDAO">
<ref bean="stateDAO"/>
</property>
</bean>
------------------------------------------------------------------------------------------
application_servlet.xml

<bean id="dwrController" class="org.springframework.web.servlet.mvc.ServletWrappingController">
<property name="servletClass">
<value>uk.ltd.getahead.dwr.DWRServlet</value>
<!--<value>org.directwebremoting.servlet.DwrServlet</value>-->
</property>
<property name="initParameters">
<props>
<prop key="debug">true</prop>
</props>
</property>
</bean>

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

</props>
</property>
<property name="interceptors">
<list>
<ref bean="clickStreamInterceptor"/>
<ref bean="openSessionInViewInterceptor"/>
<ref bean="mainMenuHighlighterInterceptor"/>
<ref bean="userMenuHighlighterInterceptor"/>
<ref bean="adminMenuHighlighterInterceptor"/>
</list>
</property>
</bean>


------------------------------------------------------------------------------------------
dwr.xml
<?xml version="1.0" encoding="UTF-8"?>
http://www.getahead.ltd.uk/dwr/dwr10.dtd">

<dwr>
<allow>
<convert
converter="bean"
match="com.realdevelopment.videonary.web.utils.AjaxUtils"/>

<create
creator="spring"
javascript="ajaxUtils" class = "uk.ltd.getahead.dwr.create.SpringCreator" >
<include method="getStateList"/>
<param name="beanName" value="ajaxUtils"/>
<!-- nothing's going to change if i comment this line-->
<param name="location" value="/WEB-INF/applicationContext.xml"/>

</create>
</allow>

</dwr>

But when i tun it i get an error like this
missing spring creator while creating ajaxUtils.js

When I debug dwr source it encounter this error
org/springframework/beans/factory/BeanFactory does not exist.

I would appreciate if someone could help me and tell me how can fix this problem.

As far as I remember dwr  2 uses spring  namespaces which is a Spring 2 feature. So I suggest you to upgrade to Spring 2.0.x before you start. I believe that You will face no serious problem  in this upgrade.
----------------------------------------------------------------------------------
I had once configured  spring with DWR old version. As far as I remember you had two options to configure dwr:
1- defining the dwr servlet  in web.xml
2- defining the dwr servlet as a bean in spring context files.

I can see that you have configured both. I guess this is wrong. Check this out.
Take away that servlet "dwr-invoker" from the web.xml but don't touch the main servlet. It is configured correctly.
And in the simpleUrlHandlerMapping bean, take away all of those


<prop key="dwrSomething">dwrController</prop>
and replace them with the red line in the end of the props like this:
<property name="mappings">
<properties>
<prop key="/first.htm">firstController</prop>
<prop key="/last.htm">lastController</prop>
<!-- This mapping is required for DWR / Spring configuration -->
<!-- NOTE: This mapping should always be the last line cause it handles
all the calls which are not catched by prev mappings -->
<prop key="/**/*">dwrController</prop>
</properties>
</property>

This was the trick that we used to use with dwr 1 to let spring map dwr from inside. If you have more problems, I suggest you to join the spring and dwr mailing list. This must have been a frequently asked question out there and you see lots of related questions and answers that might be useful as well.
