JHipster provides tools to generate a project with a Java stack on the server side (using Spring Boot) and a responsive Web front-end on the client side (with Angular/React and Bootstrap). It can also create microservice stack with support for Netflix OSS, Docker and Kubernetes.
To enable generation of the cloud artifacts, the users can use the cloud build option in the Ballerina.toml file. Use docker to generate just the Docker image and the Dockerfile and use k8s to generate Kubernetes artifacts as well. Minimal sample config TOML files would look something like the following: Ballerina.toml file:
The docker-compose.yml file is used to define an application's services and includes various configuration options. For example, the build option defines configuration options such as the Dockerfile path, the command option allows one to override default Docker commands, and more. [ 32 ]
Vagrant is written in Ruby, but it can be used in projects written in other programming languages such as PHP, Python, Java, C#, and JavaScript. [7] [8] Since version 1.6, Vagrant natively supports Docker containers, which in some cases can serve as a substitute for a fully virtualized operating system. [9]
The installation of a JVM or Java interpreter on chips, devices, or software packages became an industry standard practice. The catch is that since there are multiple JVM implementations, on top of a wide variety of different operating systems, there could be subtle differences in how a program executes on each JVM/OS combination, possibly ...
Apache ZooKeeper is an open-source server for highly reliable distributed coordination of cloud applications. [2] It is a project of the Apache Software Foundation.. ZooKeeper is essentially a service for distributed systems offering a hierarchical key-value store, which is used to provide a distributed configuration service, synchronization service, and naming registry for large distributed ...
Most application servers load classes from a deployed EAR file as an isolated tree of Java classloaders, isolating the application from other applications, but sharing classes between deployed modules. For example, a deployed WAR file would be able to create instances of classes defined in a JAR file that was also included in the containing EAR ...
The AWT is part of the Java Foundation Classes (JFC) — the standard API for providing a graphical user interface (GUI) for a Java program. AWT is also the GUI toolkit for a number of Java ME profiles. For example, Connected Device Configuration profiles require Java runtimes on mobile telephones to support the Abstract Window Toolkit.
