appng application

Welcome to appNG

appNG is a web application platform and a web application framework, based on Apache Tomcat and the Spring Framework.

With appNG, you can build your own applications and deploy them to the platform within minutes.

appNG is very well suited to create and operate your own application platform as a service (aPaaS).

Core Features

  • Clear separation of concerns following the MVC paradigm

  • Declarative UI definition using schema-safe XML files

  • Writing business logic by implementing a handful of interfaces

  • Automatic parameter-binding and type conversion

  • Built-in support for paging, filtering sorting

  • Out-of-the-box support for JPA and Spring Data

  • Built-In connection pooling using HikariCP

  • Database schema migrations powered by Flyway

  • Built-In role based access control, which allows using field-based access

  • Easily provide your own SOAP or REST based webservices

  • Fully supports internationalization (i18n)

  • Easy deployment by providing a repository mechanism

  • Configurable caching powered by Hazelcast

  • Cluster support and horizontal scaling

  • Powerful administration tools, including a graphical user interface (GUI), but also a command line interface (CLI) and a REST-client

  • Supports the Bean Validation API

  • Supports indexing and searching, powered by Lucene

  • Customizable templating mechanism

  • Configurable and extendable authentication mechanism (local, LDAP etc.)

  • Provides job scheduling powered by Quartz

  • Provides tooling for common tasks like resizing images, sending emails, geo-locating, report generation etc.

  • Provides a large set of commonly used libraries such as Apache Commons or Jackson

  • Workflow and business process management support by embedding the Camunda BPMN Process Engine

  • Can serve JSP-content that can make use of the appNG tag library

  • Multi-tenancy allows to separate or group applications

  • Rapid protoyping enables you to design your user interface without writing one line of Java code

Getting started

📎

The dollar sign ($) at the beginning of a line denotes the command prompt. Depending on your operating system and shell you might see other signs like %, # or >. This sign is not part of the command to be executed.

Download and run the appNG standalone version

appNG is available as a standalone version, suitable for evaluation and testing purposes.

The standalone version also comes with appNGizer, the REST-based administration tool for appNG.

The standalone version can be found here: https://appng.org/appng/builds/stable/appng-standalone-1.22.1.zip

Check that Java >= 1.8 is available in your system’s path:

$ java -version
openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-1~bpo8+1-b11)
OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)

Unzip the file, change into the extracted folder and run

./appng.sh
📎

When running under Windows, use appng.bat.

Wait a few seconds, until the console output stops, then visit http://localhost:8080/manager in your browser.

Sign-in with the username admin and the password @ppNG$42.

📎

On the first run, some unpacking and installation operations are performed, this my take a few seconds. The subsequent starts will be much faster.

If you accidentally misconfigured your appNG instance, you can force a clean re-installation with the -i option:
./appng.sh -i

Download and run the appNG web-application version

If you run appNG in production you should use the web-application version, which is a standard web application archive (WAR-file).

For further documentation on installing appNG go to the README of the appNG web-application.

Create your first appNG application

Using the appNG Maven Archetype, you can easily create your first own application.

Therefore, the following command must be used (replace mygroupid and myartifactid with the desired values):

$ mvn archetype:generate -DgroupId=mygroupid -DartifactId=myartifactid -DarchetypeGroupId=org.appng -DarchetypeArtifactId=appng-archetype-application -DarchetypeVersion=1.22.1 -DinteractiveMode=false

Next, change into the created project folder and run mvn package.

In the target folder, a file named myartifactid-1.0-SNAPSHOT-<yyyyMMdd-HHmm>.zip should have been generated. This file is the application archive.

Deploying the application

The next step is to deploy the application through a local repository, e.g. the application archives are served from the local file system.

During installation of the appNG standalone version, a local repository has been created at /path/to/appng-standalone-1.22.1/repository/. So the first step is to copy myartifactid-1.0-SNAPSHOT-<yyyyMMdd-HHmm>.zip to this location.

💡

You can also build the application archive directly in the repository folder by using the Maven option -DoutFolder=/path/to/appng-standalone-1.22.1/repository/

Next, we use the appNG CLI to install the application and to activate it for the site manager (that has been created during installation).

In /path/to/appng-standalone-1.22.1/appng/WEB-INF/bin, execute the following commands:

$ ./appng install-application -n myartifactid -v 1.0-SNAPSHOT -r Local
$ ./appng activate-application -s manager -a myartifactid

Both commands should return without any message, meaning they where successful.

📎

You can also use the appNG Manager or the appNGizer to install and activate an application. To see a list of available CLI commands, execute ./appng or ./appng -h.

If you configure the appNGizer Maven Plugin for your project, you can automatically install and activate your application after the build.

The final step is to reload the site manager. Therefore, login at http://localhost:8080/manager and click on the reload-icon shown next to the site in the overview. A message "Site has been reloaded." should appear.

After a re-login (see details below), a new navigation item named MYAPPLICATION should appear on the site’s navigation on the left. When clicking it, you see the results of your very first appNG application. Congratulations!

📎

During installation, the application’s role Admin has been added to the appNG’s built-in Administrators group, to which your user belongs to. Since the groups of a user are determined once during login, you need to re-login to apply the newly received permissions.

For the following updates of your application, this step is therefore not necessary.

What’s next?

You should import the Maven project into your favorite IDE. Then start browsing the code to get an idea of how an appNG application works. You should also take a look at the Developer Guide.

You may also want to check out appNGizer at http://localhost:8080/appNGizer. The user manual can be found here: https://appng.org/appng/docs/1.22.1/appngizer/html/appngizer-user-manual.html
