Racer API | AnyPoint Speedway

Image
Anypoint Speedway ( The MuleSoft API Race Where Acceleration Meets Integration ) is launched with Season 3. So, Muleys all around the world get ready to RACE . Once we scroll through the  instructions , we see a need for Racer API, which will be used to compete in the race. Currently, Racer API can be built in any of the platforms, all it needs is a public endpoint with implementation as per specification . But, we are the MuleSoft developers, so let's build the API in MuleSoft. If you are a beginner or professional Muley, this article will help you implement the Racer API and participate in the race. Let's fasten up the seatbelt and start developing the  Racer API . Anypoint Speedway has made our lives easier by providing the readily available specification file. Pre-requisite racerId To enter the race, the RACER is required to register for the race and get a racerId. 1. Go to Anypoint Race API, and Click on Request Acces...

Configure Custom Domain in Private Space : CloudHub 2.0

Image
 With CloudHub 2.0, applications are deployed in public spaces or private spaces. Private space isolates the applications deployed, and different network customizations can be done within the private space. Earlier in CloudHub 1.0, DLB used to be configured to balance the incoming load along with configuring the custom/vanity domain instead of using *.cloudhub.io We can configure vanity/custom domains in the private space, avoiding accessing the applications through the default *.cloudhub.io domain. Configuring the custom domain will require the public certificate and the private key as a prerequisite. Generating the self-signed public certificate and the private key For simplicity, we will try to create certificates for the wildcard domain. To generate the self-signed public certificate and private key, we will require OpenSSL . 1. Create a config file as below, name it config.cfg , and change the values as per the domain detail...

Experimenting Recursion in DataWeave - Fibonacci Series

Image
  In various programming languages, recursion is a process in which a method or function calls itself to simplify a complicated problem. Understanding recursive solution sometimes become difficult. Let's try to solve a mathematical problem through recursion with a twist by using DataWeave . The Fibonacci series is a generic use case that recursion can solve. This is a very generic question in programming interviews. Photo by Natalya Letunova on Unsplash What is Fibonacci Series? A Fibonacci series is a set of integers starting with 0 followed by 1, and a series continuing with the sum of the preceding two integers in the sequence. For example, F n =0,1,1,2,3,5,8,13,21,34... Mathematically, F 0 =0 F 1 =1 F n =F (n-1) + F (n-2) Now transforming the above logic in the form of a recursive function to find the nth digit in the Fibonacci series. DataWeave Recursive Function: %dw 2.0 output application/json fun fib_r(n)= if...

DateTime formatting using xp20:format-dateTime ()

xs:dateTime Format In XML, we generally use xs:dateTime(xs:xmlns="http://www.w3.org/2001/XMLSchema") data type to store date time data. The generic representation of date time, that is supported by xs:dateTime in xml: YYYY-MM-DDThh:mm:ss[.SSS][Z|(+|-)hh:mm] Example :  2019-09-11T10:16:31.943+05:30 Code Description Example YYYY represents a 4-digit year 2019 MM represents a 2-digit month 09 DD represents 2-digit date 11 hh represents 2-digit hours 10 mm represents minutes in 2-digits 16 ss represents seconds in 2-digits 31 SSS represents milliseconds 943 T represents time separator T Z represents UTC time zone or 0 time zone offset (+|-)hh:mm represents time zone offset +5:30 Few more valid examples : 2019-09-11T21:32:52, 2019-09-11T21:32:52+02:...

Create Delimited String from XML Nodes and Vice Versa in SOA 12c

A delimited string is a string representation of data separated by a delimiter(e.g. ","). A simple representation of the delimited string will look like. Delimited String Examples Sample-1-- Delimiter as ","        Value1,Value2,Value3   Sample-2-- Delimiter as "|"        Value1|Value2|Value3 If we want to represent the above set of delimited values in the form of an XML document under some root and parent tag. The representation will look like this. XML Example <root xmlns="http://test.com/sample/xml">   <Values>     <value>Value1</value>     <value>Value2</value>     <value>Value3</value>   </Values> </root> Sometimes we may need to convert values coming in delimited string to an xml document or vice versa. Since delimited strin...

Import and Export MDS artifacts in SOA 12c

Image
Oracle SOA-MDS (Metadata Store) repository can be used to access artifacts that can be shared among various SOA composites. For example, we have one common schema for a business fault that is consumed by various applications. Instead of having a localized copy of that schema file in each SOA composite, we can have it in a centralized repository (SOA-MDS). Another benefit of using SOA-MDS is that we can change the file at runtime and need not redeploy the complete code. While developing SOA composites, we use SOA design-time repository, later these changes can be synced to the SOA servers. In this article, we will discuss 2 ways to sync the artifacts available in the SOA design-time repository and the SOA servers. Establishing the connection to SOA-MDS in Jdeveloper. Using SOA em console or Fusion Middleware control console. Moving a file between SOA composite to SOA design-time MDS repository Let's assume, we created a businessFault.xsd which wi...
