DWRValidator not working in Struts 2.1.6
Hi,
I'm getting an NPE when trying to use DWR validation in Struts 2.1.6.
Basically, porting a Struts 2.0.x app that used DWR validation.
The ValueStackFactory is null during the invocation and this throws the NPE
while calling valueStackFactory.createValueStack();
In normal invocation, all is fine.
How is the valueStackFactory set ? . Do i need to add any config so that the
DWR flow initializes valueStackFactory properly?
Below is the stacktrace and web.xml config:
[4/24/09 17:25:15:942 IST] 0000002b DWRValidator E

Done - https://issues.apache.org/struts/browse/WW-3138 . I've mentioned
about the method name not being picked up as well.

thats a bug ..
xwork version 1.2.3
com.opensymphony.xwork.ActionProxyFactory
public abstract ActionProxy createActionProxy(String namespace, String actionName, Map extraContext, boolean executeResult, boolean cleanupContext) throws Exception;
}
xwork 2.1.2
com.opensymphony.xwork.ActionProxyFactory
public ActionProxy createActionProxy(String namespace, String actionName, String methodName, Map<String, Object> extraContext, boolean executeResult, boolean cleanupContext);
the only changes are addition of methodName and the 4th extraContext param changes to Map<String,Object>
do you want to put in a bug report?
good catch!
Martin

I meant that there is a problem with DWRValidator.java , not the
documentation.
Referring to
http://svn.apache.org/viewvc/struts/struts2/trunk/plugins/dwr/src/main/java/org/apache/struts2/validators/DWRValidator.java?revision=670170
(hope
this is the latest?) , the line :
ActionProxy proxy = actionProxyFactory.createActionProxy(inv, namespace,
mapping.getName(), mapping.getMethod(), *true*, *true*);
had to be changed to :
ActionProxy proxy = actionProxyFactory.createActionProxy(namespace,
mapping.getName(), mapping.getMethod(), ctx);
in order to make the validation work.
Also, the mapping.getMethod() returns null , so we can't do validation on
any other method than "execute"
I wanted to know if i'm missing anything here, or is this a bug with
DWRValidator?
Thanks,
Joseph

RE: DWRValidator not working in Struts 2.1.6
Posted by Martin Gainty <mg...@hotmail.com>.
seems to be a disconnect between xwork and struts
the 3rd parameter is a map
extraContext - a Map of extra parameters to be provided to the ActionProxy
xwork is the higher authority since it is a base library..here is the doc from
xwork 1.2.3
createActionProxyhttp://www.opensymphony.com/xwork/api/com/opensymphony/xwork2/ActionProxyFactory.html
public abstract ActionProxy createActionProxy(String namespace,
String actionName,
Map extraContext,
boolean executeResult,
boolean cleanupContext)
throws Exception
Creates an ActionProxy for the given namespace and action name by looking up the configuration. The ActionProxy
should be fully initialized when it is returned, including having an ActionInvocation instance associated.
Parameters:namespace - the namespace of the actionactionName - extraContext - a Map of extra parameters to be provided to the ActionProxyexecuteResult - flag which tells whether the result should be executed after the actioncleanupContext -
Returns:ActionProxy
Throws:
Exception
apparently Struts Doc is out of synch with xwork doc
huihoo gets it right
ActionProxy
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.
and yes please file a JIRA in Struts Documentation
Thanks

Re: DWRValidator not working in Struts 2.1.6
Posted by j alex <st...@gmail.com>.
Martin,
I tried with :
ActionProxy proxy = actionProxyFactory.createActionProxy(namespace,
mapping.getName(), "execute", ctx);
Somehow the method name is coming in as null, so i hardcoded it to execute
for now ; need to see why.
This seems to work fine, i'm getting the errors as an alert box on the page,
but that's a different story.
Should i open a JIRA for this ?
Thanks,
Joseph

Re: DWRValidator not working in Struts 2.1.6
Posted by j alex <st...@gmail.com>.
Hi Martin,
I had seen the configs in the struts-showcase, and used all of them as-is ;
just added a javascript fn. to invoke DWR and was getting the NPE. So, looks
like there's something broken in the default distro. I'll try your
suggestion of using :
*
public* ActionProxy createActionProxy(String namespace, String actionName,
String methodName, Map<String, Object> extraContext, *boolean*executeResult,
*boolean* cleanupContext);
instead of :
*public* ActionProxy createActionProxy(ActionInvocation actionInvocation,
String namespace, String actionName, String methodName,*boolean*executeResult,
*boolean* cleanupContext);
Hope this is what you meant?
Thanks,
Joseph

RE: DWRValidator not working in Struts 2.1.6
Posted by Martin Gainty <mg...@hotmail.com>.
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>
<allow>
<create creator="new" javascript="validator">
<param name="class" value="org.apache.struts2.validators.DWRValidator"/>
</create>
<convert converter="bean" match="com.opensymphony.xwork2.ValidationAwareSupport"/>
</allow>
<signatures>
<![CDATA[
import java.util.Map;
import org.apache.struts2.validators.DWRValidator;
DWRValidator.doPost(String, String, Map<String, String>);
]]>
</signatures>
</dwr>
<!-- 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
documentation available at
http://struts.apache.org/2.1.6/struts2-core/apidocs/com/opensymphony/xwork2/ActionProxy.html
hope that answers your question

Re: DWRValidator not working in Struts 2.1.6
Posted by j alex <st...@gmail.com>.
martin,
i had seen the StrutsPrepareFilter API and as it says "Prepares the request
for execution by a later StrutsExecuteFilter filter instance. " . I've both
the StrutsPrepare and Execute filters configured plus the DWR servlet.
You were mentioning a working example of DWRValidator in the showcase, but i
couldn't find it.
My understanding is that when a DWR request is sent - it goes thru
StrutsPrepareFilter , StrutsExecuteFilter (which executes the Action
preceded by interceptor stack) , finally DWRServlet. So, by the time the
request reaches DWRServlet, it would have done the validations and the
errors would be populated.
The point i'm confused is that in DWRValidator doPost method, there's again
a call to execute the Action like :
ActionProxy proxy = actionProxyFactory.createActionProxy(inv, namespace,
mapping.getName(), mapping.getMethod(), *true*, *true*);
proxy.execute();
and this fails for some reason since valuestackfactory is null.
Thanks,
Joseph

StrutsPrepareFilter documentation is available at
http://struts.apache.org/2.1.6/struts2-core/apidocs/org/apache/struts2/dispatcher/ng/filter/StrutsPrepareFilter.html
there is a brand new feature that musachy put in svn on monday to specifically work-around action execute
i would ping him to see if this made was built into latest distro
