WSO2 ESB Tutorial Issue - wso2

I just want know if somebody here already tried this tutorial:
https://docs.wso2.com/display/ESB490/Sending+a+Simple+Message+Through+the+ESB
I followed the instructions strictly but after I deployed my SampleCApp Composite Application project to carbon 4.4 based server(wso2esb-5.0.0), the SimpleStockQuoteProxy is nowhere to be located in the management console.
I hope you can help me with this especially those who have encountered this issue. I want to know, how did you fix this?
Thank you in advance.

What kind of OS are you using? If you are using Windows, unfortunately, it doesn't work. At least I haven't found a way to make it work through the Developer Studio.
But you can login into the management console, then in the Main tab, Carbon Applications, Add and upload your exported .car file. Refresh the List of Carbon Applications a few times until you see it there or until it shows the red message that the uploaded Carbon Application is faulty. You can click on the message and remove the faulty application, if this happens.
You can export the file by right-clicking on the Composite Application Project in the Developer studio and selecting Export Composite Application Project.

expo dev client application doesn't open

I'm trying to use expo-dev-client to add react-native-sms-retriever library to my project because expo doesn't have a library that supports reading sms messages. In expo documentation, it's suggested that I should use expo-dev-client to add custom native code. You can see the documentation here: https://docs.expo.dev/workflow/customizing/#developing-apps-with-custom-native-code
I followed all of the steps in starting guide for expo-dev-client. https://docs.expo.dev/clients/getting-started/
But when I start my app using "expo start --dev-client" and run on android, a white screen is shown for a second and then I'm redirected to expo go application page.
in console, the following 2 lines are written:
› Opening on Android...
› Opening com.droppgroup.masterclean://expo-development-client/?url=http%3A%2F%2F127.0.0.1%3A8081 on LDN_L21
I tried this on real device and 2 other emulators but I got the same result. I reinstalled expo go application and it still doesn't work.
Any suggestions on what I can do to make this work?
The issue may be a problem with Expo config plugins, which configure native code for an Expo project, by configuring Info.plist for example. I am currently experiencing a similar issue, though after scanning the QR code, I am directed to a black screen in my Expo Dev Client which crashes and takes me back to the home page. The Dev Client worked perfected until I ran expo add react-native-bluetooth-classic, since I am trying to access iOS bluetooth APIs. I am currently working on this issue, but I just wanted to point you in the direction of config plugins since the examples Expo gives for customizing your runtime have config plugins registred in the "plugins" property of app.json.
It may be necessary to create your own plugin, though I am unsure.
Please let me know if you come up with any fixes, and so will I.

download and run exe from chrome browser using c++ plugin

I have a webpage where when I click a button, it should download an exe from a url and the exe should get automatically invoked without user intervention.
In Internet Explorer I achieved this through activex control ( .ocx ) deployed as a .cab file.
I am planning to extend this to chrome and firefox platform too. ( atleast chrome for the first step ).
I don't want to use Java applet ( need to remove java dependency ). I know I could achieve this through Firebreath plugin but clearly this is not a good time to dive into NPAPI plugin ( since NPAPI is already being fading out. Chrome has begun phasing out NPAPI ).
When I looked into alternative Plugin technologies to NPAPI, I stumbled upon Google Native Client. On further reading I got to know Nacl too won't fit my needs since os calls api will not work in nacl ( I hope URLDownloadToFile api or createprocess or shellexecute wouldn't work. Correct me if I am wrong ).
Should I go for Native Messaging? Is there anyother alternative technology am missing ? Guide me Please .
NPAPI until it goes away will let you do what you want; other than that Native Messaging is the only option.
As others have mentioned, this is a Really Bad Idea(tm).
Thanks all the people . I finally settled with Launch Application Using Custom Protocol Handler . http://msdn.microsoft.com/en-us/library/ie/aa767914(v=vs.85).aspx . This fitted my needs .
As suggested above, Chrome's native messaging appears to be the way to go - on Chrome.
First, have a look here: This blog entry shows that native messaging can be used to launch "calc.exe". I've yet to try it myself - but it looks promising:
https://plus.google.com/+FrancoisBeaufort/posts/jdTrmmZL9Xh
One thing to keep in mind is that the Native Messaging technique will only work from a Chrome Extension, which opens up an entire set of related questions.
(1) Can Chrome extensions be installed for all users using group policy? or via the registry?
-Yes, according to http://www.chromium.org/administrators/pre-installed-extensions
Later edit: only "published" extensions can be added via the registry. see - https://developer.chrome.com/extensions/external_extensions
(2) Can you detect whether an extension is already installed?
-Yes, Chrome Extension: How to detect if an extension is installed using Content Scripts
So maybe its possible to have a two-phase process:
-Your users will head to the web page, which will test for the extension (using #1 above)
-If its not there, have the users download and install the .exe (this will require interaction).
-The .exe will deploy the extension files and register it for Chrome (using #2 above)
-On subsequent visits, the already-installed extension can be used to launch/communicate with the now-already-installed .exe (using Native Messaging)

SharePoint-hosted Task pane app not authenticating

Summary:
I have an Office 365 E3 account where I'm trying to deploy a Word task pane app that will read some SharePoint list data. Right now, I'm just trying to get the task pane app to load, however, it shows the Office 365 login page (in the pane) but does not do anything after clicking Login.
Details:
I went through the instructions provided here:
http://msdn.microsoft.com/en-us/library/office/fp179815.aspx
Basically, I create an App for SharePoint configured as SharePoint-hosted, then in the same project, added an App for Office (Task Pane App for Word only). The SharePoint app also has a custom document library.
I am able to install the app to my App Catalog, and it correctly shows up in Site Contents where I see it being provisioned to the app web. I can also launch Word 2013 with the Trusted App Catalog configured correctly, and I am able to see my Task Pane App and insert it. When I click Insert, it loads it but prompts for credentials.
I am using the same credentials all throughout this exercise so by virtue of being able to install and deploy the SharePoint app, you can trust that I'm providing the right credentials.
It also appears the custom document library is never created - I wonder if both suffer from the same underlying issue.
I encountered the same problem and the solution provided in the answer below did not help.
After some desparation i created a taskpane app using the Napa Cloud App, opened the application in Visual Studio and went looking for differences.
In the Taskpane app manifest.xml file i found the following entries which were missing in my own application manifest:
<AppDomains>
<AppDomain>https://login.microsoftonline-int.com</AppDomain>
<AppDomain>https://login.microsoftonline.com</AppDomain>
</AppDomains>
This solved my problem and cured one horrible friday.
I was able to get this to work. It turns out doing a Deploy from Visual Studio (whether you right-clicked Deploy or F5-debug), the installation of the app isn't enough.
To make it work, I skipped doing a Deploy all together, but instead published my app. I then took the .app file and loaded it in my App Packages folder, and then deployed it from there.
Unfortunately, I don't know the difference between the two, but I'm assuming it has something to do with provisioning the app web for the Office App.

Wso2 ESB don't deploy car

I am trying to remove the car of an Aplication.
I removed the .car by management console and removing the file in wso2esb-4.0.3/repository/deployment/server/carbonapps but wso2 dont put nothing in the log and dont remove the artifacts, I cant shutdown the server.
When I remove de .car and upload the file again the server dont re-deploy anything
The initial problem was that some artifacts had disapeared from management console, but the .car was deployed, a other instance of the .car are in the temp directory.
This was a known issue [1] and fixed from WSO2 ESB 4.5.0. I think its recommended to use the latest version of the product since in that case many bugs fixed and many new features are added to the product. You can find the latest distribution of WSO2 ESB 4.7.0 latest release here [2]
Hope this will help you.

We had this problem too. It can also happen when you have deactivated a proxy within the web console.
Be sure all components from the specific .car file are running.
Uninstall the application (within the web-console)
Wait until all components are gone
If this is not working - you need to stop the server and remove all components (from that .car) from the file system manually. We did that a couple of times and it worked. (search for all affected components and remove them).
We finally solved the issue by upgrading to a new version of WSO2 ESB.

Deploying a Firebreath plugin on a webpage without manual installation

Recently I have been experimenting with Firebreath and developed a plugin in order to showcase my c++ projects on my portfolio website. I would like to make it easy for users to look at the projects without downloading files if they are new on my website.
The only issue I have at this point is that when users visit my page, they will receive a message indicating the plugin is missing. I would like to have an option for the users to automatically install my plugin without having to manually download and run it.
The plugin is mainly targetted at Windows users, since the applications are as well. I intend to support Google Chrome, Firefox, Internet Explorer. Currently I am using a MSI installer to install the plugin.
I have found a question similar to this, but I still needed to save the MSI installer and run it.
My question is: What would be the best way to implement this?
There isn't any way to "automatically" do what you want to do. The closest that I have heard of would be to use a java applet that would download and install the plugin for them. This can be pretty reliable on Mac but far less reliable on windows (for a number of reasons, among which the fact that many windows users don't have java installed and that Chrome blocks java applets by default without intervention by the user).
Other options include:
Creating a CAB file installer (only works on IE)
Creating a XPI firefox extension that packages the plugin (requires restarting the browser, only works on firefox)
Creating a CRX chrome extension that packages the plugin (only works on Chrome)
Microsoft ClickOnce used to work pretty well for one click installs of MSI files from a web page, but recently I think it doesn't work on many (if any) browsers; haven't seen it used in awhile, anyway.
There is no "automatic" way to install plugins; that would be considered a severe security issue. This is probably the #1 reason that plugins are as uncommon as they are.
do what adobe does,
create a tiny activeX application downloader, sign the activeX from with cheap SSL
when a user, enters your site, he will automatically be downloading this tiny ActiveX, after installation complete, inside the tiny ActiveX, have some type of batch script to download the EXE from remote server and silently install it.
adobe does this, on every reboot in boot.ini or startups
very easy
