Infrastructure Manager Java API

This project offers an API that allows to connect to the Infrastructure Manager REST API. For more information about the IM capabilities check: IM Web.

The javadoc for this project can be found here: Javadoc



This project has been created with maven. To compile it you will need at least Apache Maven 3.0.5 and Java 1.8. Maven will take care of downloading all the extra dependencies needed for the project.


1.2.1 From Maven

To compile the project you need to be in the same folder as the pom.xml file and type:

mvn clean install

this command compiles the code and executes the tests. If you want to compile the code without the tests you can use:

mvn clean install -DskipTests

When the compilation finishes you will have a target folder. Inside you can find the compiled java classes and the packaged jars. The jar im-java-api-x.x.x-jar-with-dependencies.jar includes all the libraries needed by the im-java-api and can be used independently. The jar im-java-api-x.x.x.jar contains only the im-java-api compiled code and needs external libraries to work. The external libraries needed by the project are specified in the pom.xml

1.2.1 From a tarball

The code for the library can also be found in the im-java-api github repository. To download the source code:


After the download you have to untar the package and inside the folder compile the project like in the maven section:

tar zxf im-java-api-v0.4.9.tar.gz
cd im-java-api-0.4.9
mvn clean install

Once the compilation finishes in the folder target you can find the jar.

Also you can download the jar already packaged with all the dependencies from:



This project does not need any configuration files to work. If you want you can define a to log the REST service calls. To configure the logger you have to create a file and set the logger properties. The file of the tests can help you with the logger configuration.


The tests defined in the class InfrastructureManagerTest show how to use the im-java-api. Also check the following lines to see some examples of use:

2.1 From Java

2.1.1 Create the API client

InfrastructureManager im = new InfrastructureManager("IM_ENDPOINT", "AUTH_FILE_PATH");

When creating a new client you have to specify a valid IM URL, and an authorization file path with the credentials required for the infrastructure deployment. More information about the authorization file can be found here: Auth file. You can also check the authorization file used for the tests that is available in 'src/test/resources/'.

2.1.2 Create and destroy an infrastructure

// Infrastructure creation based on a TOSCA file
InfrastructureUri newInfrastructureUri = im.createInfrastructure(readFile(TOSCA_FILE_PATH), BodyContentType.TOSCA);
// Infrastructure destruction

The 'im' client always returns a POJO with the information of the call. If an error occurs, an ImClientErrorException is thrown. This exception contains the error message and the error code returned by the server.

2.1.3 Create authorization headers

Since version 0.4.5 the infrastructure manager allows to use the AuthorizationHeader class and different builders to create the authorization headers. The usage is as follows:

AuthorizationHeader ah = new AuthorizationHeader();
Credentials imCred = ImCredentials.buildCredentials().withUsername("user").withPassword("pass");
Credentials vmrcCred = VmrcCredentials.buildCredentials().withUsername("user").withPassword("pass").withHost("host");
Credentials dummyCred = DummyCredential.buildCredentials();
InfrastructureManager im = new InfrastructureManager("IM_ENDPOINT", ah);

2.2 From the Orchestrator

The im-java-api is used to facilitate the connection between the Orchestrator and the IM.
The Orchestrator is mainly developed in Java and the IM in Python, so this library acts as a mediator between this to systems.
The IM offers a REST API that returns JSON messages and the im-java-api transforms this messages in Java classes that are used by the Orchestrator.

This library library is automatically deployed with the Orchestrator (due to maven dependencies).
Anyhow, if you want to substitute the library packaged with the war, the location inside the war is WEB-INF/lib/im-java-api-X.X.X.jar.
To use this library from the Orchestrator you only have to used the Orchestrator normally and create a deployment that uses the IM endpoint.
More info about the Orchestrator can be found here.
