OSLC 2020 Reference Implementation

Introduction

Reference implementation of four OSLC Servers covering each of the 4 OSLC Domains:

How to run

Follow the 3 sections below to:

Run the OSLC Servers
Populate with sample data
Navigate to OSLC servers

Run the OSLC Servers

There are multiple options to run the OSLC Server.

Using built-in servers directly

This is the simplest option if you don't want to use anything except JDK and a Maven installation. Prerequisites:

JDK 17
Maven 3

Follow these steps to start 4 servers:

cd src/
mvn clean install
# if you have Docker running, you can run integration and acceptance tests
# mvn clean verify -Pacceptance

cd server-rm/
mvn clean jetty:run-war

cd ../server-cm/
mvn clean jetty:run-war

cd ../server-qm/
mvn clean jetty:run-war

cd ../server-am/
mvn clean jetty:run-war

After following these steps, proceed to the steps listed in the next section Navigating OSLC servers.

Using Jetty-based containers with Docker

If you wish to run 4 OSLC servers as 4 containers similar to how one would deploy them in the cloud, you could follow steps listed in this subsection. Prerequisites:

JDK 17 (only for non-Docker builds)
Maven 3.9 (only for non-Docker builds)
Docker CE 19 or equivalent
Docker Compose v2

Docker Compose setup was also tested with Rancher Desktop 1.0.1.

cd src/
# Using Docker Compose
docker compose up --build

Make sure all is up and running:

$ docker ps
CONTAINER ID   IMAGE               COMMAND                  CREATED          STATUS          PORTS                    NAMES
7a719e58b909   refimpl-server-am   "/docker-entrypoint.…"   2 seconds ago    Up 1 second     0.0.0.0:8803->8080/tcp   oslc-refimpl-am
ea678fe26dbe   refimpl-server-qm   "/docker-entrypoint.…"   10 seconds ago   Up 10 seconds   0.0.0.0:8802->8080/tcp   oslc-refimpl-qm
e7cdcb427f78   refimpl-server-cm   "/docker-entrypoint.…"   19 seconds ago   Up 18 seconds   0.0.0.0:8801->8080/tcp   oslc-refimpl-cm
37b905ccc0a0   refimpl-server-rm   "/docker-entrypoint.…"   28 seconds ago   Up 27 seconds   0.0.0.0:8800->8080/tcp   oslc-refimpl-rm

After following these steps, proceed to the steps listed in the next section Navigating OSLC servers.

To see logs:

docker logs oslc-refimpl-am -f

Running on Tomcat in Docker

cd src/
docker compose -f docker-compose.tomcat.yml up --build

Running on Tomcat via Maven

cd src/
mvn clean install
# if you have Docker running, you can run integration and acceptance tests
# mvn clean verify -Pacceptance

cd server-rm/
mvn clean package cargo:run -D"cargo.maven.containerId=tomcat10x" -Pwith-jstl-impl

cd ../server-cm/
mvn clean package cargo:run -D"cargo.maven.containerId=tomcat10x" -Pwith-jstl-impl

cd ../server-qm/
mvn clean package cargo:run -D"cargo.maven.containerId=tomcat10x" -Pwith-jstl-impl

cd ../server-am/
mvn clean package cargo:run -D"cargo.maven.containerId=tomcat10x" -Pwith-jstl-impl

Populate with sample data

Once running, you can populate the reference implementation servers with some OSLC resources using one of these 2 alternatives:

With a Kotlin plugin or IntelliJ: run the client under src/client-toolchain/src/main/kotlin/co/oslc/refimpl/client/Main.kt
As a java program: run the client using java -jar client-toolchain/target/client-toolchain.jar.

Parameters:

Use --help to see all accepted arguments.
If you omit the argument, all 4 servers will be initialized.
You can initialize one or more servers with - for example - --init-servers am,qm.

Navigate to OSLC servers

After that, OSLC servers are available at the following URLs:

Currently, OAuth 1.0 with Basic fallback is enabled only on the OSLC RM server (port 8800). Use admin:admin credentials for Basic authentication. In order to enable OAuth support on other servers, uncomment the following lines under src/main/webapp/WEB-INF/web.xml of each server:

<filter>
    <display-name>CredentialsFilter</display-name>
    <filter-name>CredentialsFilter</filter-name>
    <filter-class>co.oslc.refimpl.rm.gen.servlet.CredentialsFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>CredentialsFilter</filter-name>
    <url-pattern>/services/*</url-pattern>
</filter-mapping>

Swagger endpoints are available at the following URIs (use sp_single as a serviceProviderId where required):

Root Services for the RM Server is under: http://localhost:8800/services/rootservices (similar for other servers).
