Problem with "double" type elements in JAXB

I have recently faced quite a lot of problem using JAXB objects to invoke SOAP webservices.

There were several elements declared as :
<xs:simpleType name="someAttr"><xs:restriction base="xs:double"/></xs:simpleType>

When I used "wsimport" command line tool to generate Java classes for the WSDL, all those attributes generated as

private double someAttr;

What happened later was all the values were transformed automatically to scientific notation like : 2.85292746E8

This was a major issue, as the actual values were getting truncated. 

After a long search and trial and error, I found an easy solution to my problem, to change the declaration 
private double someAttr;

To : private BigDecimal someAttr;

No value truncation or transformation happened after that.

Chatbots and Oracle Cloud Services

Thanks to Oracle A-Team, I had a chance to work with Chatbots. 3 pure NodeJS applications, on couple of Oracle Cloud platforms and Facebook messenger, and my chatbot was running. Let me explain, the architecture a bit. To start with, following is the simple representation of how it works. Message Platform Server : Is a NodeJS application, deployed on Oracle Application Container cloud, acts as a channel between Facebook Messenger and the chatbot engine. It simply converts the incoming messages from Facebook and sends it to chatbot readable format. Also, when chatbot replies, it converts to Facebook readable formats and passes it to messenger. Chatbot Engine : Is a NodeJS application, which communicate with some REST APIs based on a conversation flow document and moves the flow of the conversation from one state to another. Flow JSON : Where we document, every state of a conversation and which APIs to call to generate a response. For example, at the beginning of the con...

Rich Text Editor - Oracle JET

Oracle JET has a lot of excellent UI components, but according to Murphy's law, client always comes up with something which you don't have at your disposal. So, driven by one of my client's requirements, I created a Rich Text Editor or WYSIWYG editor for Oracle JET. This is based on Quill JS and fully customizable. 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...

Exception Handling in ADF

This blog will give you an overview on how you can successfully deal with unhandled Runtime exceptions in an ADF application. This will give you an idea of: How to catch the unhandled exceptions. Write a separate log file with stacktrace and thread dumps. Redirect the user to an static error page #1. Catch unhandled exceptions :  Create a class "MyExceptionHandler" which extends : oracle.adf.view.rich.context.ExceptionHandler. 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...
