Capture parameters from ESS screen

Question

Hi All,
I have created a custom webdynpro application for ESS. The custom application gets displayed when a link gets clicked on the Benefits screen. The link that is clicked is the SAP standard link and it passes some parameters. How do I capture these parameters in my custom webdynpro application ?
Thanks,
Tom

Tom,
I'm not sure about the protocol being used for transfer of these parameters, but assuming that HTTP or HTTPS is being used, you can try following code in your interface view's Startup plug handler. If you have not changed the default names, it will be named 'onPlugDefault' in your interface view controller.
    IWDProtocolAdapter protocolAdapter = WDProtocolAdapter.getProtocolAdapter();
    IWDRequest request =  protocolAdapter.getRequestObject;
    Map reqParams =  request.getParameterMap();
You can iterate through this map and see all parameters and values being passed.
        Iterator it = reqParams.entrySet().iterator();
        while (it.hasNext())
               Map.Entry pairs = (Map.Entry)it.next();
               //pairs.getKey().toString() gives key value and pairs.getValue().toString gives value associated with key.
               //Code for storing parameters will go here.  
Hope this helps.
Vishwas.
