Problem getting request parameters in HTTP GET in Struts 2
I was trying to get a parameter from a Http GET. The get from jsp looks
like this:
a href=/providerDetail.action?drProviderId=1000Provider 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)
{
MapInteger, DrProvider providerMap =
(Map)session.get(provider_map);
if(providerMap != null)
{
provider = providerMap.get(drProviderId);
}
}
else //go to database
{
provider = service.getProvider(drProviderId);
}
return SUCCESS;
}
RE: Problem getting request parameters in HTTP GET in Struts 2
Thanks for the response.
I did that. The request obtained by implementing RequestAware is the same as
the one obtained from ServletActionRequest.getRequest().
None of them worked. Actually, I did get the parameter map from the request,
and it contained null data.
Have you tried the scenario, did it work for your application?

Why do n't you let your action implement RequestAware interface and then get
parameter from the request map.

RE: Problem getting request parameters in HTTP GET in Struts 2
We found a post in the mailing list that reported the same problem. Check it out. The final solution of it was that the user had to implement a customized map class, which was pretty nasty. Is this something we have to go through, or is there better solution? Is this a bug in S2?

I still get null for the parameter. Some additional info. The request is actually a StrutsRequestWrapper instance. I did the debug, the whole http content on the server side looks like this. You can see the drProviderId is in the get.
