Detect User Language : Oracle Bots

Oracle Bot comes with a very sophisticated language detection and translation service. You can attach either a Microsoft or Google service to the environment and make use of it within your bot. Oracle Bots dev guide talks about it : https://docs.oracle.com/en/cloud/paas/mobile-suite/develop/localization.html#GUID-997ED305-D011-4E89-9440-566092A4870A

But, these translation services are not free. So for my development purposes I created a custom component, which does the same for me but for FREE.

Introducing Yandex APIs (https://tech.yandex.com/translate/). It is simple and easy to use. And most importantly it is free.
Yandex supports over 90 different languages. The only thing you need to do is, register and create an API key for yourself.

Step 1:
Register and create an API key : https://translate.yandex.com/developers/keys

Step 2:
Download the custom component from my GitHub : https://github.com/sohamda/CustomComponents/tree/master/detect_language

Step 3:
Update the "detect_language.js" and add your key to the detectLanguage() function.

Step 4:
Update "registry.js" to add this new custom component.
'DetectLanguage': require('./detect_language/detect_language')

Step 5:
Add a string variable in the dialog flow, named "detectedLocale".

detectedLocale: "string"

Then update the dialog flow to use this custom component, followed by a "Switch" component in order to decide what to do once you detected the language.


detectLanguage:
  component: "DetectLanguage"
switch:
  component: "System.Switch"
  properties:
    variable: detectedLocale
    source:
      values:
 - "en"
 - "nl"
  transitions:
    actions:
      en: <ENGLISH_STATE>
      nl: <DUTCH_STATE>
      NONE: <EXCPETION_STATE>

 You can use as many as transitions you want in your switch. In the above example I just did two.

Once this is done, test your bot.

That's it!.

Happy "Bot"-ing. :)

Rich Text Editor - Oracle JET

Github project download: https://github.com/sohamda/JET-Web-Components/tree/master/rich-text-editor I will explain in this blog, on how to integrate it in your own Oracle JET project. 1. Create and initialize your JET application and then put the downloaded web component inside "src\js\jet-composites" folder. 2. Once copied update your viewModel first. Add a snippet for passing the default content to be displayed by the editor after load. 3. Update view to load this editor Above you can see the "toolbar-options" property, that controls which options you should display to user on the editor. Those are basically the forma...

Write a separate log file with stacktrace and thread dumps. Redirect the user to an static error page #1.

Override handleException() method.     public void handleException(FacesContext facesContext, Throwable throwable, PhaseId phaseId) throws Throwable {         // this method is going to create a separate file with stacktrace and thread dumps         writeException(throwable);         // redirect to error page         redirectToErrorPage(facesContext);     }  Create a fo...

Layout Management & CSS Classes with Oracle JET

Oracle JET provides automatic responsive layout using CSS classes. So that, from large screens to small screens the application fits itself the best possible way. JET’s layout management are based on 2 types of CSS classes “Responsive Grid” and “Flex”. Responsive grid classes which deals with size, number of columns and functions of a particular <div>. Naming convention of these classes are oj- size - function - columns sizes can be: sm, md, lg, xl functions can be: hide, only-hide columns can be: any number between 1 to 12.   Just like Bootstrap, JET also divides the width of the available space into 12 columns, so for example, if you want a section of your page should take up atleast 5 columns if you divide the available screen into 12 columns, you need use : oj- size -5. Now comes the size part, you need to define that for each size of the screen, from hand-held mobile devices to large or extra large desktop screens. With combination with theses gr...
