  • Rich modalpanel events not populating form values

    So here is a problem I was running into, I usually use rich:modalpanel just to display some data to the user, but the other day I needed to collect some input. After happily submitting my page all the submitted values were null, what the hell. After some research here are my conclusions on this problem.

    We need to put “form” elements inside the modalPanel in order for this to work, and make sure that the ui:insert in our template is not nested within out top form.

    Reason for this is because of where modalpanel is appended to the DOM, that is also a reason why we have a4j:form inside the panel.

  • Invoking Webservice Methods from Java

    This is my helper method for invoking webservices from java. One bonus perk is that this handles the exception when we are using self signed certificates by providing our own HostnameVerifier. This could be more generalized but all I needed was to invoke this one server.

    	/**
	 * Invoke webservice to retrive data
	 * 
	 * @param 
	 *            Return type the service will return
	 * @param T
	 * @param methodName
	 *            name of method to execute
	 * @param methodArgument
	 *            need to match the methods in the webservice
	 * @return
	 */
	public  T invokeWebserviceService(Class T, String methodName,
			Object... methodArgument) {
		T result = null;
		try {
			HttpServletRequest req = getRequest();
			String host = req.getServerName();
			String schema = "http";
			if ("https".equals(req.getScheme())) {
				schema = "https";
				// Need to overide HostnameVerifier otherwise it throws a
				// exception when we are using selfsigned certificates
				HostnameVerifier hv = new HostnameVerifier() {
					public boolean verify(String urlHostName, SSLSession session) {
						return true;
					}
				};
				HttpsURLConnection.setDefaultHostnameVerifier(hv);
			}

			String wsdlURL = schema + "://" + host
					+ "/webservices/RiskBean"
					+ schema.toUpperCase() + "?wsdl";
			URL url = new URL(wsdlURL);

			String ns = "http://reporting.ws.com/";
			QName qname = new QName(ns, "RiskService"
					+ schema.toUpperCase());
			QName port = new QName(ns, "RiskBean"
					+ schema.toUpperCase() + "Port");
			QName operation = new QName(ns, methodName);

			ServiceFactory riskServiceFactory = ServiceFactory.newInstance();
			Service riskService = riskServiceFactory.createService(url, qname);

			Call call = riskService.createCall(port, operation);
			result = (T) call.invoke(methodArgument);
		} catch (Exception e) {
			e.printStackTrace();
		}
		return result;
	}

    Hopefully someone finds this helpful.
