KB20395: How to Answer Prompts in a Custom Report Event Handler Using Prompt Answer XML in MicroStrategy Java Web SDK 9.4.x.

Using the Strategy Java Web SDK 9.4.x, it is possible to pass in prompt answer xml as a parameter in the request when a specific report is run. This type of customization is helpful when the answer XML is already known and stored in the user's session either as a session attribute or as a temporary cookie. This can be accomplished using a custom report event handler. For more information about the Strategy page execution flow and the event handling process, see the following link:
Processing Events During Page Execution
Create a Custom Report Event Handler with the following code definition:

package customclasses.handlers;
import com.Strategy.web.beans.AggregatedEventHandler;
import com.Strategy.web.beans.EnumEventHandlerTypes;
import com.Strategy.web.beans.EnumReportBeanEvents;
import com.Strategy.web.beans.ReportBean;
import com.Strategy.web.beans.RequestKeys;
import com.Strategy.web.beans.WebBeanException;
import com.Strategy.web.beans.WebEvent;
import com.Strategy.web.beans.WebException;
public class AnswerPromptinReportEventHandler extends 

AggregatedEventHandler implements EnumReportBeanEvents {
    WebEvent event;
    ReportBean rb;
	
    //change the report ID to reflect a valid report in the custom environment
    String strReportID = "2C825EA14436B7FFBAA94B960814EDEA";
	
    //the prompt answer XML, this can be retrieved from a session attribute or cookie in a customized environment
    String answerXML = "<rsl lcl=\"1033\"><pa pt=\"4\" pin=\"0\" did=\"98EE6D294C3B1F5157214B954C50DA48\" tp=\"10\">2007</pa><pa pt=\"7\" pin=\"0\" did=\"6144DFEA4AC1D541B8FCEE9F2A720767\" tp=\"10\"><mi><es dirty=\"1\"><at did=\"8D679D4F11D3E4981000E787EC6DE8A4\" tp=\"12\" stp=\"3072\" n=\"Subcategory\" disp_n=\"Subcategory\"/><e ei=\"8D679D4F11D3E4981000E787EC6DE8A4:23\" emt=\"1\" art=\"1\" disp_n=\"Computers\" disp_id=\"1\"/><e ei=\"8D679D4F11D3E4981000E787EC6DE8A4:25\" emt=\"1\" art=\"1\" disp_n=\"TV's\" disp_id=\"2\"/><e ei=\"8D679D4F11D3E4981000E787EC6DE8A4:31\" emt=\"1\" art=\"1\" disp_n=\"Action\" disp_id=\"3\"/><e ei=\"8D679D4F11D3E4981000E787EC6DE8A4:26\" emt=\"1\" art=\"1\" disp_n=\"Video Equipment\" disp_id=\"4\"/><e ei=\"8D679D4F11D3E4981000E787EC6DE8A4:46\" emt=\"1\" art=\"1\" disp_n=\"Soul / R&B\" disp_id=\"5\"/></es></mi></pa></rsl>";
	
    public AnswerPromptinReportEventHandler() {
        super(EnumEventHandlerTypes.HANDLER_TYPE_REPORT);
    }
	
    public boolean processRequest(RequestKeys requestKeys) throws WebException {
	
        // Retrieve the incoming event from the RequestKeys
        event = getWebEvent(requestKeys);
		
        if (event == null) {
            // Let the default handler worry about this
            return handleDefaultRequest(requestKeys);
        }
		
        //display the current event:
        System.out.println("Current Event: " + event.getID());
        rb = (ReportBean) getWebComponent();
		
        if (rb == null) {
		
            // Let the default handler worry about this
            return handleDefaultRequest(requestKeys);
        }
        try {
            if (rb.getObjectID().equalsIgnoreCase(strReportID)) {
			
                //This is the report - pass answer xml in the request
                System.out.println("Adding prompt answer xml to request");
                requestKeys.add("promptsAnswerXML", answerXML);
            }
        } catch (WebBeanException e) {
            e.printStackTrace();
        }
        return handleDefaultRequest(requestKeys);
    }
}
