Deploying Spring Boot Applications on Google Application Engine (GAE)

I previously blogged about how to how to deploy a Spring Boot application to Flexible VM's on Google Cloud Platform as shown below.

In this example below I use Google Application Engine (GAE) to deploy a Spring Boot application without using a Felible VM which is alot faster and what I orginally wanted to get back to doing when I first did this previously. It short this is using the (more...)

Uploading Tiles into Pivotal Cloud Foundry Operations Manager from the Ops Manager VM directly

When deploying PCF, you start by deploying Ops Manager. This is basically a VM that you deploy into your IaaS system of choice and it orchestrates the PCF installation. The installation of PCF is done by you through a web interface that runs on the Ops Manager VM. Into that web interface, you can load various "tiles". Each tile provides a specific set of functionality.

For example, Ops Manager comes with a tile for Bosh (more...)

Installing Pivotal Cloud Foundry (PCF) on Google Cloud Platform (GCP)

I decided to install PCF 1.8 onto Google Cloud Platform today and I thought the experience was fantastic and very straight forward. The GCP Console is fantastic and very powerful indeed. The steps to install it are as follows

Here are some screen shots you would expect to see along the way when using Operations Manager

Finally Once Installed here is how to create an ORG, USER and (more...)

Accessing the Cloud Foundry REST API from SpringBoot

Accessing the Cloud Foundry REST API is simple enough to do as shown in the example below using curl we can list all our organizations.

Cloud Foundry REST API -

Below shows just the organizations name and I am filtering on that using JQ, if you wnat to see all the output then remove the PIPE or JQ. You have to be logged in to use "cf oauth-token"

Declarative REST Client Feign with Spring Boot

Feign is a declarative web service client. It makes writing web service clients easier. To use Feign create an interface and annotate it. It has pluggable annotation support including Feign annotations and JAX-RS annotations. Feign also supports pluggable encoders and decoders.

In this example I show how to use Spring Cloud / Spring Boot application with Feign. The source code for this is as follows

1. Include the required maven dependency for Feign (more...)

WS Security – enabling passwordDigest authentication in an Oracle FMW environment

To have a basic level of authentication on web services (especially where there's no transport layer security) without having to pass clear text passwords in the WS Security headers. 

The concepts are fairly generic but this post is highly Oracle Fusion middleware specific. There can be complex decision tree (see [1]) involved when selecting the 'appropriate' level of security for any system. As security involves trade-offs between cost, performance, usability (more...)

Managing shared metadata (MDS) in a CI enviornment

Goals and Summary:
* Package shared metadata in a SOA environment and make it widely distributable (SOA MDS [2], Servicebus, maven artifact repository) 
* Associated sample:  
* Key command (if you use the associated pom file) 
mvn deploy -Dpassword=*****

Having worked on a wide range of projects, I came to the realisation that SOA can mean vastly different things in different (more...)

OTN Appreciation Day: Programmatically Dismiss Popup

A couple of years ago I blogged about fading user feedback.  Also Duncan Mills had a solution for this, as did Frank Nimphius. Just recently I was triggered by a blogpost of Shay Schmeltzer that in ADF this can be done completely different and 100% declarative. Where Shay's example is declarative, in this blogpost I describe how to do the same when this popup is created

Pushing a Docker image using Docker Hub on Pivotal Cloud Foundry

In this example I will show how to push a Docker image to Pivotal Cloud Foundry (PCF) using Docker Hub. You can use your own private Docker Registry BUT here I am using Docker Hub in this example.

The example spring boot application which can easily created as a Docker Image is per this spring guide below.

1. First we need to ensure the docker is enabled on Diego as shown below.

Displaying Pivotal Cloud Foundry application Instances Buildpacks or Docker Images using CF CLI

I was recently asked how you could display all PCF application instances detected buildpack OR docker image being used from the command line. The CF REST API gives you all of this information and more as per the documentation below to list all applications.

This API call gives you lots of information so to filter that a fellow work college created this script to get just the output we want. You (more...)

Reading VCAP_SERVICES and VCAP_APPLICATION from a Spring Boot Rest Controller in PCF

Note for myself: Reading PCF System and ENV variables
package com.example;

import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

Version Control for PL/SQL

Today, we are happy to announce the new version of Gitora, Gitora 2.0, the version control tool for PL/SQL developers.

Gitora helps PL/SQL developers manage their source code in Git easily. It helps them lock database objects to prevent edits from other users regardless of the editor they use, create, change branches, merge code from other schemas or databases and see the source code in the database change instantly, generate diff scripts automatically and (more...)

Using Oracle 12c with Pivotal Cloud Foundry Applications

In this post I walk through what it would take to access Oracle 12c using a spring boot application deployed to Pivotal Cloud Foundry PCF all from my Macbook Pro. Of course this can be done outside of an isolated laptop like my Macbook Pro but handy while doing DEV/TEST and still being able to use Oracle 12c.

  • Oracle 12c instance
  • PCFDev 
  • Git Client

1. First you will need a 12c Database and the (more...)

Using H2 Console in development with Spring Boot then NOT when deployed to Pivotal Cloud Foundry

Frequently when developing Spring based applications, I will use the H2 in memory database during your development process. H2 ships with a web based database console, which you can use while your application is under development. It is a convenient way to view the tables created by Hibernate and run queries against the in memory database. In this post I show what is required to set this up as well as what it means to (more...)

Spring Boot on Google Cloud Platform (GCP)

I recently created a demo which can be used to deploy a basic Spring Boot application on Google Cloud Platform (GCP). There isn't really anything specific in the code to make this work on GCP BUT the maven pom.xml has what is required to make it one simple command to send this app to GCP.

$ mvn gcloud:deploy

You can run an App Engine application in two environments, the standard environment and the flexible (more...)

Replacing legacy Java EE application servers with microservices and containers

Lightbend recently ran a survey with more than 2000 JVM developers and the results just got published. The survey was launched to discover:  correlations between development trends and IT infrastructure trends, how organizations at the forefront of digital transformation are modernizing their applications, and real production usage break-downs of today‚Äôs most buzzed about emerging developer technologies. While you can download the complete results from the official website, I would love to highlight some particular (more...)

Pivotal MySQL*Web – Web Based Spring Boot / Bootstrap Application for Pivotal MySQL tile (p-mysql)

I have been recently working on a web based interface to Pivotal MySQL Tile which can be deployed to Pivotal Cloud Foundry and bound to a p-mysql service instance for instant access to the MySQL DB. Known as PivotalMySQL*Web this is a browser based SQL tool rendered using Bootstrap UI for MySQL PCF service instances which allows you to run SQL commands and view schema objects from a browser based interface. It includes the following (more...)

JHipster, Spring Boot, AngularJS and finally deployed to Pivotal Cloud Foundry

I have known about Hipster for a while and thought I would finally give it a test drive and deploy a simple scaffolded app to Pivotal Cloud Foundry. In this post I will use the p-mysql (Pivotal MySQL) rather then the ClearDB instance

1. I created a very basic "Monolithic" application as shown below.
