Pushed applications to CF or PCF you would of most likely used a manifest.yml file and at some point wanted to use variable substitution. manifest.yml files don't support that and a feature request has been asked for this as follows
With a recent customer we scripted the creation of a manifest.yml file from a Jenkins job which would inject the required ROUTE to the application by creating the manifest.yml (more...)
I had a requirement to implement a HttpSessionListener in my Spring Boot application which has no web.xml. To achieve this I did the following
1. My HttpSessionListener was defined as follows
public class SessionListener implements HttpSessionListener
protected static Logger logger = Logger.getLogger("controller");
private HttpSession session = null;
The demo below is a full working example of using Spring Boot Application which will build/deploy to Pivotal Cloud Foundry using Concourse. Concourse pipelines can easily be created within your source code as this demo shows and hence created / executed quite easily. Concourse limits itself to three core concepts: tasks, resources, and the jobs that compose them.https://github.com/papicella/SpringBootSimpleRest
Detailed instructions on how to setup/run this demo using Concourse see the link referenced above (more...)
PCF Dev is a small footprint distribution of Pivotal Cloud Foundry (PCF) intended to be run locally on a developer machine. It delivers the essential elements of the Pivotal Cloud Foundry experience quickly through a condensed set of components. PCF Dev is ideally suited to developers wanting to explore or evaluate PCF, or those already actively building cloud native applications to be run on PCF. Working with PCF Dev, developers can experience the power of (more...)

In this example I am going to show how to use IntelliJ IDEA 15 to create a service application from the IDE to be consumed by the Service Registry service in Pivotal Cloud Foundry (PCF). For more information on this service view the docs page below.http://docs.pivotal.io/spring-cloud-services/service-registry/index.html
Service Registry for Pivotal Cloud Foundry® (PCF) provides your applications with an implementation of the Service Discovery pattern, one of the key tenets of a (more...)
I created the following demo for PCF using spring boot / PCF. After showing a colleague he decided he would write a Kotlin version of the same application. It's interesting to see how the Kotlin classes differ to those of Java.https://github.com/papicella/PivotalSpringBootJPA
The Kotlin version of the same application is here.https://github.com/papicella/Kotlin-PivotalSpringBootJPA
Kotlin is a functional language developed by the JetBrains guys. Its main benefits are:

Apigee and Pivotal partnered to provide comprehensive API management capabilities that expedite the scalable delivery of apps on the powerful Pivotal Cloud Foundry platform. Apigee Edge is available for rapid deployment as a partner service in the Pivotal Network
The following link talks about this service in detailhttp://apigee.com/about/solutions/pivotal-cloud-foundry-apigee
In this blog post we walk through how we would use this Service on Pivotal Cloud Foundry 1.7 to expose Telstra SMS Api.
Working with a customer last week we determined that Spring Boot applications using Liberty Buildpack failed to allow the "Auto-Scale" service to show up "Throughput" metrics and essentially mean we couldn't scale out or down application instances using Throughput metrics.https://console.ng.bluemix.net/docs/runtimes/liberty/index.html
It turns out the Agent within the IBM Liberty buildpack isn't quite picking up application WAR files created using Spring Boot and hence "Monitoring and Analytics
" and " (more...)

I almost always use the tomcat buildpack within IBM Bluemix for my Java based applications. By default IBM bluemix will use the IBM Liberty buildpack for java apps unless you specify otherwise. The buildpacks on Bluemix can be viewed using "cf buildpacks
" and the tomcat buildpack is referred to as "java_buildpack
So to use the tomcat buildpack in a manifest.yml you would target it as follows
- name: pas-javaapp (more...)

I rarely need to save state within the Servlet Context via an application scope, but recently I did and here is what your controller class would look like to get access to the ServletConext with Spring. I was using Spring Boot 1.3.2.RELEASE.
In short you implement the "org.springframework.web.context.ServletContextAware
" interface as shown below. In this example we retrieve an application scope attribute.
There is now a new command line plugin for IBM containers on Bluemix so you can push and run docker images using CF CLI itself. The steps below show you how to set this up and I use a basic spring boot application as a docker image to test this out.Steps
Take a note of the docker local host IP. In this example it was as follows, as I test my docker image on (more...)
