the DWR configuration you will need is located at
struts-showcase\WEB-INF\dwr.xml
<?xml version="1.0" encoding="UTF-8"?>
<!-- START SNIPPET: dwr -->
<!DOCTYPE dwr PUBLIC
"-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN"
"http://www.getahead.ltd.uk/dwr/dwr10.dtd";>
<dwr>

<create creator="new" javascript="validator">

<!-- END SNIPPET: dwr -->
where the servlet would be defined in WEB-INF/web.xml configuration
<servlet>
<servlet-name>dwr</servlet-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-mapping>
<servlet-name>dwr</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>
the config files struts.xml or struts-default.xml would contain the bean
definitions for OgnlValueStackFactory e.g.
<bean type="com.opensymphony.xwork2.util.ValueStackFactory" name="struts"
class="com.opensymphony.xwork2.ognl.OgnlValueStackFactory" />
<bean type="com.opensymphony.xwork2.ActionProxyFactory" name="xwork"
class="com.opensymphony.xwork2.DefaultActionProxyFactory"/>
your webapp's
execution flow is governed by interceptors you insert into (defaultStack)
interceptor stack declaration as seen here
<interceptor-stack name="defaultStack">
<interceptor-ref name="exception"/>
<interceptor-ref name="alias"/>
<interceptor-ref name="servletConfig"/>
<interceptor-ref name="i18n"/>
<interceptor-ref name="prepare"/>
<interceptor-ref name="chain"/>
<interceptor-ref name="debugging"/>
<interceptor-ref name="profiling"/>
<interceptor-ref name="scopedModelDriven"/>
<interceptor-ref name="modelDriven"/>
<interceptor-ref name="fileUpload"/>
<interceptor-ref name="checkbox"/>
<interceptor-ref name="staticParams"/>
<interceptor-ref name="actionMappingParams"/>
<interceptor-ref name="params">
<param name="excludeParams">dojo\..*,^struts\..*</param>
</interceptor-ref>
<interceptor-ref name="conversionError"/>
<interceptor-ref name="validation">
<param
name="excludeMethods">input,back,cancel,browse</param>
</interceptor-ref>
<interceptor-ref name="workflow">
<param
name="excludeMethods">input,back,cancel,browse</param>
</interceptor-ref>
</interceptor-stack>
The ActionProxyFactory is used to create ActionProxies to be executed. It is
the entry point to XWork that is used
by a dispatcher to create an ActionProxy to execute for a particular namespace
and action name.
where xwork 1.2.3 specifies createActionProxy with 5 parameters
createActionProxy(String namespace,
String actionName,
Map extraContext,
boolean executeResult,
boolean cleanupContext)
Creates an ActionProxy for the given namespace and action name by looking up
the configuration.
instead of
ActionProxy proxy = actionProxyFactory.createActionProxy(inv, namespace,
> mapping.getName(), mapping.getMethod(), *true*, *true*);
switch the 1st arg of inv (assuming that contains action) and 2nd arg of
namespace(assuming that contains namespace) and drop getMethod() unless of
course that has the desired extraContext
then proxy.execute()
will set the ActionContext from the ActionInvocation into the desired
ActionContext
