Pushing applications to CloudFoundry the Java way

CloudFondry provides a Java API that can be used to do anything just as the CLI. Follows are the steps that shows how to connect and publish an application to CF using Java code:

1. Skip SSL validation
You may have to skip SSL validation to avoid
SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {
  public void checkClientTrusted(X509Certificate[] xcs, String string) {
  public void checkServerTrusted(X509Certificate[] xcs, String string) {
  public X509Certificate[] getAcceptedIssuers() {
    return null;
ctx.init(null, new TrustManager[] { tm }, null);

2. Connect to CloudFoundry
Connect to the CloudFoundry API endpoint (e.g. and authenticatewith your credentials:
String user = "admin";
String password = "admin";
String target = "";
CloudCredentials credentials = new CloudCredentials(user, password);
HttpProxyConfiguration proxy = new HttpProxyConfiguration("proxy_hostname", proxy_port);
CloudFoundryClientclient = new CloudFoundryClient(credentials, target, org, space, proxy);

3. Create an application
String appName = "my-app";
List urls = Arrays.asList("");
Staging staging = new Staging(null, "app_buildpack_git_repo");
client.createApplication(appName, staging, disk, mem, urls, Collections. emptyList());

4. Push the application
ZipFile file = new ZipFile(new File("path_to_app_archive_file"));
ApplicationArchive archive = new ZipApplicationArchive(file);
client.uploadApplication(appName, archive);

5. Check the application state
StartingInfo startingInfo = client.startApplication(appName);
System.out.println("Starting application: %s on %s", appName, startingInfo.getStagingFile());
CloudApplication application : client.getApplications()
System.out.printf("  %s (%s)%n", application.getName(), application.getState());

6. Disconnect from CloudFoundry
