Eclipse Californium is a Java implementation of RFC7252 - Constrained Application Protocol for IoT Cloud services. Thus, the focus is on scalability and usability instead of resource-efficiency
like for embedded devices. Yet Californium is also suitable for embedded JVMs.

and http://coap.technology/.
Build using Maven
You need to have a working maven installation to build Californium.
Then simply run the following from the project's root directory:
$ mvn clean install
Executable JARs of the examples with all dependencies can be found in the demo-apps/run folder.
Using Californium in Maven Projects
We are publishing Californium's artifacts for milestones and releases to Maven Central.
To use the latest released version as a library in your projects, add the following dependency
to your pom.xml (without the dots):
<dependencies>
...
<dependency>
<groupId>org.eclipse.californium</groupId>
<artifactId>californium-core</artifactId>
<version>2.0.0</version>
</dependency>
...
</dependencies>
...
Current Builds
You can also be bold and try out the most recent build from master.
However, we are not publishing those to Maven Central but to Californium's project repository at Eclipse only.
You will therefore need to add the Eclipse Repository to your pom.xml first:
<repositories>
...
<repository>
<id>repo.eclipse.org</id>
<name>Californium Repository</name>
<url>https://repo.eclipse.org/content/repositories/californium/</url>
</repository>
...
</repositories>
You can then simply depend on 2.1.0-SNAPSHOT.
Eclipse
The project can be easily imported into a recent version of the Eclipse IDE.
Make sure to have the following before importing the Californium (Cf) projects:
- Eclipse EGit (should be the case with every recent Eclipse version)
- m2e - Maven Integration for Eclipse (should be the case with every recent Eclipse version)
- UTF-8 workspace text file encoding (Preferences » General » Workspace)
Then choose [Import... » Maven » Existing Maven Projects] to import californium into Eclipse.
IntelliJ
The project can also be imported to IntelliJ as follows:
In IntelliJ, choose [File.. » Open] then select the location of the cloned repository in your filesystem. IntelliJ will then automatically import all projects and resolve required Maven dependencies.
Interop Server
A test server is running at coap://californium.eclipse.org:5683/.
It is an instance of the cf-plugtest-server from the demo-apps.
The root resource responds with its current version.
More information can be found at http://californium.eclipse.org/.
Another interop server with a different implementation can be found at
coap://coap.me:5683/.
