I am currently trying to incorporate a progress bar into my application to display the current progress of a task. The task, retrieves a file from a server using a web service. i do not have access to this web service and therefore cannot put any code inside it.
My code is as follows:
The method which I need to display progress of:
public URL checkout(String docCid, String fileCid)
{
String userId="aaaaaa";
FVConnectData fvData = new FVConnectData();
fvData.setWsKeyword("aaaaa");
fvData.setWsUrl("http://aaaaa.com");
FVConnector con = new FVConnector(fvData);
System.out.println("Method checkout called");
URL url = null;
try
{
//This is where the web service is called
url = con.checkoutFile(docCid, fileCid, userId, "aaaa", "aaaa", false);
System.out.println("URL: " + url.toString());
return url;
}
catch (Exception e)
{
System.out.println("ERROR: " + e.getMessage());
e.printStackTrace();
return null;
}
}
My question is this:
How can I adapt this method in order to provide my primefaces GUI with the live progress of the method to display to the user?
EDIT:
The only real examples I have found online use a random progress to display on the progress bar. I do not want this, I want the true (or close enough) progress. Also due to not being able to access the web service, I am unable to determine the size of the file before hand.

I have created a webmethod in a C# webservice that listens for Docusign to call when an Envelope status changes:
[WebMethod]
public void DocuSignConnectUpdate(DocuSignEnvelopeInformation DocuSignEnvelopeInformation)
{
//Check if null
if (DocuSignEnvelopeInformation == null)
{
File.WriteAllText("C:\\websites\\DataAPI\\datalog.txt", "Data: " + "Data is null");
}
else
{
string envelopeId = "";
try
{
//Write a line in a file
File.WriteAllText("C:\\websites\\DataAPI\\datalog.txt", "Data: " + DocuSignEnvelopeInformation.ToString());
//Get some data out
envelopeId = DocuSignEnvelopeInformation.EnvelopeStatus.EnvelopeID;
//Write Data to a file
File.WriteAllText("C:\\websites\\DataAPI\\innerdatalog.txt", "Data: " + DocuSignEnvelopeInformation.ToString());
}
catch (Exception ex)
{
// could not serialize
File.WriteAllText("C:\\websites\\DataAPI\\errorlog.txt", "Exception: " + ex.Message);
throw new SoapException(ex.Message, SoapException.ClientFaultCode);
}
}
The issue I am having is that DocuSignEnvelopeInformation argument is not being set when called, so the code keeps terminating at the if==null statement. When I run the envelope data to the API using SoapUI everything works correctly. Any ideas what I'm missing would be appreciated.
EDIT: I wanted to Add the Interface here too since I forgot it originally
[ServiceContract(ConfigurationName = "IOperations", Namespace = "https://www.docusign.net/API/3.0")]
public interface IOperations
{
[OperationContract(Action = "DocuSignConnectListener/Operations/DocuSignConnectUpdate")]
[XmlSerializerFormat]
string DocuSignConnectUpdate(DocuSignEnvelopeInformation DocuSignEnvelopeInformation);
}
When a DocuSign webhook is set to use SOAP mode, the notification is sent as a SOAP request to your server (your listener).
If SOAP mode is off, then the notification is sent as a regular POST request with an XML body.
In your question, you say that
When I run the envelope data to the API using SoapUI everything works correctly
So it sounds like everything is worked as designed.
Ok I finally figured this out, turns out it just wasn't pretty enough so I added a decoration specifically:
[SoapDocumentMethod("http://tempuri.org/DocuSignConnectUpdate",
RequestNamespace = "http://tempuri.org",
ResponseNamespace = "http://tempuri.org",
Use = System.Web.Services.Description.SoapBindingUse.Literal,
ParameterStyle = System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
on the method and now everything works like its supposed too. Now that I look at it, it makes a lot more sense.
Hi i am using liferay/api/secure/jsonws services to upload documents, getting documents, from a outside application , in the same way i want to download the documents also, i checked my liferay jsonws , there is no method or service which i can use for download , or i don't know about it , please suggest me a way to download documents from outside application , by using jsonws or any other way is also fine.
Edit after i got to know how to download document.
Hi I tried to download liferay document from outside application by using getURl, but every time for all document i am getting liferay login page content
i have already tried get-file-as-stream json-rpc call but that also giving me null response
the code which i have used is:
final HttpHost targetHost = new HttpHost(hostname.trim());
System.out.println(targetHost.getHostName());
UsernamePasswordCredentials creds = new UsernamePasswordCredentials(username, password);
System.out.println(creds);
final AuthScope authscope = new AuthScope(targetHost);
httpclient.getCredentialsProvider().setCredentials(authscope, creds);
final AuthCache authCache = new BasicAuthCache();
final BasicScheme basicAuth = new BasicScheme();
authCache.put(targetHost, basicAuth);
final BasicHttpContext localContext = new BasicHttpContext();
localContext.setAttribute(ClientContext.AUTH_CACHE, authCache);
final HttpGet httpget = new HttpGet(hostname+"/documents/" + groupId + "/" + folderId + "/" + filename);
final HttpResponse response = httpclient.execute( httpget, localContext);
if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
final org.apache.http.HttpEntity entity = response.getEntity();
if (entity != null) {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
entity.writeTo(baos);
return baos.toByteArray();
}
}
return null;
} finally {
httpclient.getConnectionManager().shutdown();
}
}
i am adding basic auth header will correct username and password, don't know how this login page is coming, is there any permission which i need to change or any configurations issue, please help in this.
You could use the Liferay WebDav Services to download files from your document-library. The paths to download can be inspected inside of the control-panel when clicking on a file entry (WebDAV URL toogle link). The paths usually look like: /webdav/{site-name}/document_library/{folder-name}/{file-name}
Otherwise, you could mimic the request URLs Liferay creates inside the documents-media portlet to download the file entry.
But you should take care about authentication, when your files (and folders) are not visible to guests.
I've created and registered custom http module to show maintenance message to user after administrator turns on maintenance mode via configuration change.
When I pass request for html it should return custom html loaded from file, but it returns message: "The service is unavailable." I can't find that string in my entire solution. Custom log message from custom maintenance module is written to log4net logs.
... INFO DdiPlusWeb.Common.MaintenanceResponder - Maintenance mode is on. Request rejected. RequestUrl=...
Seems something is miss configured in IIS on Azure. Something intercepts my 503 response. How to fix it?
Module code
void context_BeginRequest(object sender, EventArgs e)
{
HttpApplication application = (HttpApplication)sender;
HttpContext context = application.Context;
if (AppConfig.Azure.IsMaintenance)
{
MaintenanceResponder responder = new MaintenanceResponder(context, MaintenaceHtmlFileName);
responder.Respond();
}
}
Interesting part of responder code.
private void SetMaintenanceResponse(string message = null)
{
_context.Response.Clear();
_context.Response.StatusCode = 503;
_context.Response.StatusDescription = "Maintenance";
if (string.IsNullOrEmpty(message))
{
_context.Response.Write("503, Site is under maintenance. Please try again a bit later.");
}
else
{
_context.Response.Write(message);
}
_context.Response.Flush();
_context.Response.End();
}
EDIT: I lied. Sorry. Maintenance module returns the same message for requests that expect json or html.
This answer led me to the solution.
I've added another line to SetMaintenanceResponse method.
_context.Response.TrySkipIisCustomErrors = true;
It works now. Here is more about what it exactly means.
I realize this might come across as a very basic question, but I just downloaded Xamarin three days ago, and I've been stuck on the same issue for two days without finding a solution.
Here is what I am trying to do:
Get user input, call API, parse JSON and pass data to another controller, and change views.
Here is what I have been able to do so far: I get the user input, I call the API, I parse the response back, write the token to a file, and I want to pass the remaining data to the second controller.
This is the code I am trying:
var verifyCode = Storyboard.InstantiateViewController("verify") as VerifyCodeController;
if (verifyCode != null)
{
this.NavigationController.PushViewController(verifyCode, true);
}
My storyboard setup:
Navigation controller -> routesTo -> FirstController
I have another UI Controller View set up with the following properties set:
storyboardid: verify
restorationid: verify
and I am trying to push that controller view onto the navigation controller.
Right now this line is erroring out:
var verifyCode = Storyboard.InstantiateViewController("verify") as VerifyCodeController;
giving me this error, which I don't know what it means: Could not find an existing managed instance for this object, nor was it possible to create a new managed instance.
Am I way off in my approach?
p.s: I cannot use the ctrl drag thing like the tutorial suggests because I have an asynchronous call. And I cannot under no circumstances make it synchronous. So all the page transition has to be manual.
EDIT
to anyone requesting more code or more info:
partial void registerButton_TouchUpInside (UIButton sender)
{
phone = registrationNumber.Text;
string url = url;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create (url);
request.Method = "GET";
Console.WriteLine("Getting response...");
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
if (response.StatusCode != HttpStatusCode.OK)
{
Console.Out.WriteLine("Error fetching data. Server returned status code: {0}", response.StatusCode);
}
using (StreamReader reader = new StreamReader(response.GetResponseStream()))
{
string content = reader.ReadToEnd();
if (string.IsNullOrWhiteSpace(content))
{
//Console.WriteLine(text);
Console.Out.WriteLine("Response contained empty body...");
}
else
{
var json = JObject.Parse (content);
var token = json["token"];
var regCode = json["regCode"];
var aURL = Environment.GetFolderPath (Environment.SpecialFolder.MyDocuments);
var filename = Path.Combine (aURL, "app.json");
File.WriteAllText(filename, "{token: '"+token+"'}");
// transition to main view. THIS IS WHERE EVERYTHING GETS MESSED UP
var verifyCode = Storyboard.InstantiateViewController("verify") as VerifyCodeController;
if (verifyCode != null)
{
this.NavigationController.PushViewController(verifyCode, true);
}
}
}
}
}
Here is all the info for every view in my storyboard:
1- Navigation controller:
- App starts there
- The root is the register pager, which is the page we are currently working on.
2- The register view.
- The root page
- class RegisterController
- No storyboard id
- No restoration id
3- The validate view
- Not connected to the navigation controller initially, but I want it to be connected eventually. Do I have to connect it either way? Through a segue?
- class VerifyCodeController
- storyboard id : verify
- restoration id : verify
If you guys need more information I'm willing to post more. I just think I posted everything relevant.
I am using SPLongOperation to run a lengthy operation. After completing, the gears page redirects back to the original page from which the long operation was launched. I am not able to write anything to the oriignal page using SPLongOperation.Endscript. Here is the code I am using
using (SPLongOperation operation = new SPLongOperation(this.Page))
{
//.......................
//.......................
StringBuilder endScript = new StringBuilder();
endScript.Append("document.write('Success!!');");
operation.End(Request.Url.ToString(), SPRedirectFlags.UseSource, HttpContext.Current, String.Empty, endScript.ToString());
}
You won't be able to write anything to the calling page, a new http request has been made to show you the page with the spinning wheel while your operation is under progress and then you're redirected back to the specified url (using a new request).
The easiest way to show a success message is to pass a specific querystring to your calling url by replacing your string.empty parameter with something like
operation.End(Request.Url.ToString(), SPRedirectFlags.UseSource, HttpContext.Current, "success=1");
http://msdn.microsoft.com/en-us/library/ms450341.aspx
and then on the load event, check if you have this parameter and display the relevant message (it would be better to add an item to the HttpContext.Items or doing a post instead of a get to remove the querystring but the suggested implementation will prevent you from changing your long operation call and behaviour)
Hope this will help.
Try an alert - that worked for me..
Script.Append("alert('Success!!');");
This might be of help: http://www.sharepoint-tips.com/2012/07/reporting-code-errors-when-running-code.html

}
if
(sbErrors.Length > 0)
{
longOp.EndScript("document.getElementById('s4-simple-card-content').innerHTML = \"Errors have occurred during the submission. Details: " + sbErrors.ToString() + " \";");
}
//close the dialog if there were no errors
