Tobi modular server

Tobi is a modular server framework which is Microprofile 3.0 compliant. You only plugin what you really need. Thus it is highly flexible and pluggability needs no extensive configuration. With Tobi you are not restricted to HTTP. It can serve any proprietary protocol. Currently modules exist for HTTP/S with plugins for REST, SSE and WebSocket and many features from the Microprofile orbit.

Overview

This modular server framework consists of the core server, modules, plugins and features. Modules, plugins and features can be enabled just by adding their dependency. Each module can have multiple plugins, e.g. the HTTP/S module can have one, multiple or all of JAX-RS plugin, SSE plugin and/or WebSocket plugin. Features can be used globally by all modules and plugins.

Currently only HTTP module is provided. Any other protocol can be implemented and integrated very easily (see IServerModule). There are 3 plugins that can be used with the HTTP module:

1. JAX-RS plugin
2. SSE plugin
3. WebSocket plugin

Below is an overview of the features:

• CDI Open-Web-Beans integration 2.0.11
• CDI Weld integration 3.6.3
• Microprofile Config 1.3
• Microprofile Fault-tolerance 2.0
• Microprofile Health 2.0.1
• Microprofile JWT-Auth 1.1.1
• Microprofile Metrics 2.0.1
• Microprofile Open-API 1.1
• Microprofile Open Tracing 1.3.1
• Microprofile Restclient 1.2.0

User guide

To start using Tobi as a server you need to add the following dependency:

<dependency>
	<groupId>com.ai-republic.tobi</groupId>
	<artifactId>server-core</artifactId>
	<version>1.0.0</version>
</dependency>

Then you can decide whether you like to use OpenWebBean (OWB) or WELD as your CDI container and add the appropriate dependency.

Using OpenWebBeans

To use OpenWebBeans add the following dependency:

<dependency>
	<groupId>com.ai-republic.tobi</groupId>
	<artifactId>feature-cdi-owb</artifactId>
	<version>1.0.0</version>
</dependency>

Using WELD

To use WELD add the following dependency:

<dependency>
	<groupId>com.ai-republic.tobi</groupId>
	<artifactId>feature-cdi-weld</artifactId>
	<version>1.0.0</version>
</dependency>

Adding a module

To add a module like HTTP/S to you project you either just add the plugin(s) as which have the dependency of the module or add the module explicitly like:

<dependency>
	<groupId>com.ai-republic.tobi</groupId>
	<artifactId>module-http</artifactId>
	<version>1.0.0</version>
</dependency>

Adding a plugin

To add JAX-RS (REST) support simply add the following dependency (this will also add the dependency to module-http):

<dependency>
	<groupId>com.ai-republic.tobi</groupId>
	<artifactId>plugin-http-jaxrs</artifactId>
	<version>1.0.0</version>
</dependency>

Now you just need to add your javax.ws.rs annotated resources to your project. Similar you can use/combine other plugins such as plugin-http-sse or plugin-http-websocket.

Adding a feature

The feature-logging-java and feature-mp-config features are automatically added with the core-server. To add other features to use in your project just add the appropriate dependency like:

<dependency>
	<groupId>com.ai-republic.tobi</groupId>
	<artifactId>feature-mp-faulttolerance</artifactId>
	<version>1.0.0</version>
</dependency>

Configuration

Configuration can be done in 2 ways. Either you place a microprofile-config.properties file in your projects META-INF folder and configure the port parameters like this (recommended):

workerCount=5
host=localhost
http.port=8080
http.ssl.port=8443
http.keystore.file=~/keystore.jks
http.keystore.password=changeit
http.truststore.file=~/cacerts.jks
http.truststore.password=changeit

NOTE: All properties starting with http. belong to the HTTP/S module . http.port and http.ssl.port are the ports under which the HTTP/S module will be servicing. In fact if you would like Tobi only to accept HTTPS you simply don't add the http.port property. See also the documentation on the HttpModule.

Another way to configure these properties is to pass them as system properties on startup.

Starting the Tobi server

Then just call:

Tobi.start();

to start your Tobi server. It will automatically discover all your resources.

Example application
