Application Request parameter

Does anyone know the API to get the passed application parameter tkrough the request? We can add request parameter to the WebDynPro iView. I need to know how to retrieve it from WebDynPro.

I tried below but it does not contain the parameters.

Any help is much appreciated.

HttpServletRequest request =((com.sap.tc.webdynpro.services.sal.adapter.core.IWebContextAdapter) WDWebContextAdapter.getWebContextAdapter()).getHttpServletRequest();

Or

server = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("Server");

Best regards,
