Problem getting request parameters in HTTP GET in Struts 2

[Duan, Bin]

I was trying to get a parameter from a Http GET. The get from jsp looks
like this: 

<a href=/providerDetail.action?drProviderId=1000>Provider Name 

The providerDetail.action maps to ProviderAction class. In the action
class, I have a setDrProviderId() method, but found the id was not set.
Then I tried to get the id from
ServletActionRequest.getRequest().getParameter("drProviderId"), but
still did not get anything.

 

I debugged the code, in the request object, I saw request input as "GET
/providerDetail.action?drProviderId=1000", this pretty much meant the
parameter was sent to the server side correctly. But
request.getParameter("drProviderId") returned me null. 

 

If I switch to use form POST, my setDrProviderId() method was still NOT
called, but I could get the id from
request.getParameter("drProviderId").

 

This problem will almost be a show stopper for our project to use
Struts. Anybody has any ideas of what could be wrong? 

 

I am using Struts 2.1.6. I tried both on oc4j and JBoss. 

 

 

 

Following is my struts.xml file

 

 

<struts>

 

    <package name="dataReceiving" extends="struts-default">

 

        <action name="listProvider" method="listProvider"

 
class="com.claritas.mms.radish.dataReceiving.DrProviderAction">

            <result>/dataReceiving/ProviderList.jsp</result>

        </action>

        <action name="providerDetail" method="providerDetail"

 
class="com.claritas.mms.radish.dataReceiving.DrProviderAction">

            <result>/dataReceiving/ProviderDetails.jsp</result>

        </action>

    </package>

 

</struts>

 

Following is my DrProviderAction class

 

    public void setDrProviderId(String id) 

    {

        this.drProviderId = new Integer(id).intValue();

}

 

    public String providerDetail() 

    {

        Map map = request.getParameterMap();

 

        String sid = request.getParameter("drProviderId");

        drProviderId = new Integer(sid).intValue();

        //check if the 

        if(session != null) 

        {

            Map<Integer, DrProvider> providerMap =
(Map)session.get("provider_map");

            if(providerMap != null) 

            {

                provider = providerMap.get(drProviderId);

            }            

        }

        else //go to database

        {

            provider = service.getProvider(drProviderId); 

        }

        

        return SUCCESS;

        

    }
