pass parameter inside action path in struts-config.xml

[shah rah]

I have a search screen where in if there is an exact match I have to show the detail page diretcly. If the search returns more than one record then I show a list of records. The user double clicks and then reaches the detailed page.

When there is a direct match inside my action class.

if(results.size()==1){ 
 //search returns single record
Group grp = service.getGroupDetails(groupid);
session.setAttribute("groupDetails", grp);
return mapping.findForward("showGroupDetails");
}

if search returns a list of records

<tr id = '<bean:write name="group" property="groupID"/>' 
 document.forms[0].action='showGroupDetails.do?groupid=' + id;
document.forms[0].submit();
>

Firstcase the url is http:.../'showGroupDetails.do
secondcase my url is like http:.../'showGroupDetails.do?groupid=1


I want same kind of url for both. how can this be achieved? Is there way I can change my struts-config to accept query parameter?

This should be very easy...just append the parameters to the end of the path after calling findForward. The problem is that a forward cannot be modified after it is created. Maybe there is an easier way to do this, but I created this utility method for doing this:

    public static ActionForward addParameterToForward(
            ActionForward forward,
            String paramName,
            String paramValue)
    {
        // define the new path
        StringBuffer newPath = new StringBuffer();
        newPath.append(forward.getPath());
        if (newPath.toString().indexOf('?') == -1)
        {
            newPath.append("?");
        }
        else
        {
            newPath.append("&");
        }
        newPath.append(paramName);
        newPath.append("=");
        newPath.append(paramValue);
 
        // copy the forward with the new path
        ActionForward newForward = new ActionForward();
        newForward.setName(forward.getName());
        newForward.setPath(newPath.toString());
        newForward.setRedirect(forward.getRedirect());
        newForward.setContextRelative(forward.getContextRelative());
 
        return newForward;
    }
