Bonita Java API

Q&A

I am trying to deploy a process in a BAR file using Bonita’s Java API. I was able to create a Business Archive object from the BAR file and log in to the server but when I try to deploy the process, I get the following error:

This is the code:

        org.bonitasoft.engine.api.APIClient apiClient = new APIClient();
        try {
            apiClient.login("install", "install");

            final LoginAPI loginAPI = TenantAPIAccessor.getLoginAPI();
            APISession session = loginAPI.login("install", "install");
            ProcessAPI processAPI = TenantAPIAccessor.getProcessAPI(session);

            BusinessArchive businessArchive = createBusinessArchive(barFilePath);
            System.out.println("BusinessArchive created successfully!");

            ProcessDefinition processDefinition = processAPI.deploy(businessArchive);
            System.out.println("Process deployed: " + processDefinition.getName());

            loginAPI.logout(session);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static BusinessArchive createBusinessArchive(String barFilePath) throws IOException, InvalidBusinessArchiveFormatException {
        File barFile = new File(barFilePath);

        try (InputStream inputStream = new FileInputStream(barFile)) {
            // Read BusinessArchive from InputStream

            return BusinessArchiveFactory.readBusinessArchive(inputStream);
        }
    }
}

I am using maven to build the dependencies.
