It includes the server which is a simple REST application designed to work over the web (via https), making it possible for many apps across many servers to leverage a central jans-client-api service for OAuth 2.0 security.

Packaging and running the application


  1. Verify file route of next parameters in clientApi_ConfigurationEntryDN field:jansConfDyn configuration json:

Source Packaging

You can build the jans-client-api server using Maven. The code is available in Github.

Create a folder to clone ${PATH_REPOSITORY}, and clone inside.

git clone
cd jans-client-api
mvn clean install -Dmaven.test.skip=true -Dcompile.jans.base={JANS_AUTH_SERVER_CONFIG_PATH, example: /etc/jans}

After the built is finished jans-client-api-server.war is generated in ${PATH_REPOSITORY}/jans-client-api/server/target/.

Jetty 11 Deploy

Download jetty 11 zip, here a link:

Create a folder to unzip Jetty ${PATH_FOLDER_JETTY}, and unzip Jetty inside.

export JETTY_HOME=${PATH_FOLDER_JETTY}/jetty-home-11.0.9
mkdir jetty-base
export JETTY_BASE=${PATH_FOLDER_JETTY}/jetty-base/
cd jetty-base
java -jar $JETTY_HOME/start.jar --add-module=server,deploy,annotations,webapp,servlet,resources,http,http-forwarded,threadpool,jsp,websocket,logging/slf4j,logging-jetty
cp ${PATH_REPOSITORY}/jans-client-api/server/target/jans-client-api-server.war $JETTY_BASE/webapps/
java -jar  $JETTY_HOME/start.jar jetty.http.port=9999

After jans-client-api server is started, status can be checked using health-check url: http://localhost:9999/jans-client-api-server/health-check.

Compile and running tests

Compile with tests

mvn clean install -Djans.base=/etc/jans

Djans.base is the conf path of the local running jans-auth-server

Running tests

mvn test -Djans.base=/etc/jans

Djans.base is the conf path of the local running jans-auth-server

Running tests with external jans-client-api

mvn test -Dtest.client.api.url=http://localhost:9999/jans-client-api-server/

Dtest.client.api.url is the url of a running jans-client-api-server
