  Introduction The idea behind this blog article is to generate fast a microservice application with an Oracle JET front end. Simply put JHipster is a code generation tool, that can generate all sorts of project structure, but I’m more interested in the microservice type of project. Microservices applications usually have a gateway that holds

The case story for my project implied creating a custom authentication method, which incorporates LDAP and APEX users. Firstly, it verifies if the user can connect to LDAP.

For various reasons, you may be required to mock method calls on objects which are created ad-hoc in other objects (not injected via Spring Dependency Injection) Normally, you would use PowerMock for

This is a rather short article about an error that we had during the development phase using a test H2 Database. Context We have a microservices-based application generated with the help of JHipster which, during development phase, uses an H2 Database to store dummy data.

As prerequisites, I’ve created a page with an Interactive Grid region on it, I’ve given it a Static ID (‘interactive_grid’) and I’ve saved two alternative reports (‘A’ and ‘B’, each with a different setting). In order to change the saved reports dynamically, I use JavaScript. For our case, I’ve just written code in the ‘Execute

In order to complete this task, it would be required to write some JavaScript code. It might seem complex, but don’t worry. I will keep it as simple as possible. Before we start, we will need an Interactive Grid region implemented on a page. Now, we will go to the Attributes > Advanced > JavaScript

The declarative component of this sample was build using JDev 11g (11.1.1.9.0 to be exact). I received a couple of question on how to work with this declarative component in JDev 12c projects. In general, you
