Invoking HTTPS Service Request from Oracle API Platform

Oracle API Platform’s API Implementation has two service naming convention 1) API Request 2) Service Request.

API Request – is the endpoint to which users or applications send requests for your API.

Service Request – is the URL at which your back-end service receives requests.

In this blog we are going to discuss what are the additional configuration we need to done inside API Platform Gateway Server while invoking a HTTPS Service Request URL.

Since, its HTTPS URL obviously there is associated SSL cert with that URL which is signed by Certificate Authority.

Recently, I have been doing one POC where I was invoking a Service Request HTTPS URL but it was not working and later found out it’s because of associated SSL certificate was not configured in Weblogic JKS Keystore.

Before, I get into detailed solution, let me tell you bit more about problem. At very initial stage when I tried creating an API which is in-turn calling an HTTPS service request, it was failing while invoking that service from rest POSTMAN tool and was getting “Internal Server error” as per below snap.

Create and Delete Users in Weblogic using WLST Script

In one of my recent Event engagement, I was expected to provision 50+ users in Weblogic. Creating users in Weblogic is not cumbersome process, it’s fairly easy. However, when you need to do in bulk it can take hours.

So, I just came up with simple WLST script which take an configuration file as input which contains all the server credentials required to make connectivity and list of users, description and group name etc and create and delete users in Weblogic.

Note: I have tested this script in Weblogic 12.2.1.2 but it should work in all Weblogic version as long as the beans which I have used inside python not been change in particular Weblogic Version.

Creating Users

createUserMultiGrp.properties

This is configuration file which keep server credentials and all users name along with description, group and password.

Configure Letsencrypt SSL Certificate in Weblogic 12c

Who doesn’t like the security. This is one of critical element of our IT Infrastructure. Recently I was doing one POC and got requirement to setup a valid SSL certificate in Weblogic. However, since it was just an POC we were not having any valid SSL certificate issued by some Certificate Authority. Later, I came across for one website called https://letsencrypt.org/ . Let’s Encrypt is a free, automated, and open certificate authority (CA). they give people the digital certificates they need in order to enable HTTPS (SSL/TLS) for websites, and its free, yes you heard correctly It’s FREE !!!. You don’t need to pay them at all. So if you need a valid SSL certificate for your POC or even for Production environment you can get one from them. Although their certificate comes with 3 month validity, so while using for Production environment user need to keep renewing with them with simple automated process.

In this blog we will be learning how we can generate letsencrypt SSL certificate, what’s prerequisite to get the certificate and setup that certificate in Weblogic server to enable SSL communication.

So, Lets move on. We will be doing below stuff in sequence –

  1. Get a registered domain name (This required while generating SSL Cert)
  2. Install Certbot ACME Tool and Apache HTTP Server
  3. Generate Letsencrypt SSL Certificate
  4. Configure Letsencrypt SSL in Weblogic Identity Store
