Deploying Spring Boot Applications to Pivotal Cloud Foundry from STS

The example below shows how to use STS (Spring Tool Suite) to deploy a spring boot web application directly from the IDE itself. I created a basic spring boot web application using the template engine thymeleaf. The application isn't that fancy it simply displays a products page of some mock up Products. This blog entry just shows how you could deploy this to Pivotal Cloud Foundry from the IDE itself.

1. First create a Pivotal (more...)

Java EE with NetBeans on OpenShift

Today was NetBeans Day in Munich. I had the pleasure to present one session about the integration of Red Hat's products with my famous IDE. So, I've been talking about WildFly, EAP, Git, OpenShift Online and showed all the different ways optimize your development workflow with that tool-set.

It's been roughly 100 attendees and it was a pleasure to be there. Thanks everybody for making it, even if half of Germany was on (more...)

Adaptive Form with Dynamic ADF LOV Value Binding

Previously I had a post about dynamic ADF attribute binding creation and dynamic ADF form generation - Adaptive Form with Dynamic ADF Attribute Value Binding. Blog reader was asking how to generate dynamic ADF LOV binding using similar approach. This is possible and actually documented in Eugene Fedorenko post here - Dynamic LOV binding. I will use the same piece of code to extend my sample application with dynamic ADF LOV binding support.

Here you (more...)

Apex Interactive Report: The difference between CIR and RIR

You’ve probably already used the reset functionality in an Interactive Report, but do you know the exact the difference between CIR (Clear Interactive Report) and RIR (Reset Interactive Report)?

RIR or CIR, what is it?

First, let’s explain what CIR and RIR is and how you can use it.

With CIR and RIR you can clear or reset your Interactive Report after using filters. This can be handy if you’ve applied a filter on a (more...)

Developer Interview (#DI 8) – The Red Hat Devoxx Keynote Demo Team explains it all

The last blog post about Devoxx and what happened there. Promised. But I really wanted to do this very special developer interview with the team behind the Demo. You already know everything about the technical details behind it and now it it time to let those speak, who actually implemented it.

Sit back, relax and get a #Coffee+++! Thanks to the team for taking the time!

Suppressing ADF LOV Like Operator Filtering V2

I had a post about the solution to suppress ADF LOV Like operator and prevent LOV popup loading when user is typing existing value - Suppressing ADF LOV Like Operator Filtering. Thanks to a blog reader, there was one use case found, when Like operator was not suppressed properly. This is fixed now and I would like to post updated sample application here.

Additional method is overridden in LOV VO implementation class - applyViewCriteria(ViewCriteria, boolean). (more...)

PL/SQL Webservice deployment with Apache Ant on Weblogic

I created a PL/SQL Webservice using Oracle JDeveloper. I want to use the same generated source tree for development and testing. 

Deploy/Undeploy/Redeploy
To deploy the webservice to the weblogic applications server I found some Ant deployment examples. 

<target name="deploy">
<wldeploy action="deploy" adminurl="t3://${wls.hostname}:${wls.port}" failonerror="false" name="${deploy.name}" password="${wls.password}" source="${deploy.folder}/${deploy.name}${buildnr}.war" targets="${deploy.target}" user="${wls.username}" verbose="true"/>

Fabric8 Gateway for the Unified Push Server

If you want to run the Unified Push Server behind a firewall, you still need to expose those RESTful endpoints that are accessed from the mobile apps running on the different devices:

With the help of the Fabric8 Gateway Servlet this is a fairly simple task!

I have created such a gateway that only exposes the above URLs, nothing else. Checkout therepository on github!

Have fun!

Recently i came cross a use case where i need to add  a new column into a table which being already used in production and we need to support this new changes on both version of table schema.
However gradually we will get ride of old version of table. but for now we need to support both schema.
In my case it's only related to fetch operation ,so here i am going to (more...)

Why You Should Create BPM Suite Business Object Using element (and not complexType)

In this article I describe why you always should base your business object based upon an element, instead of a complexType.

With the Oracle BPM Suite your process data consists of project or process variables. Whenever the variable is based on a component, that component is either defined by some external composite (like a service), or is defined by the BPM composite itself, in which case it will be a Business Object. That Business (more...)

JDeveloper Debugging Tips (Watchpoints & Beep)

In a previous blog post I talked about scoping breakpoints for debugging purposes, next to scoping breakpoints JDeveloper has more interesting debugging features to offer.

I created a simple example to show both the watchpoint as well as the beep functionality. To illustrate this, I created a page with an inputText and a button, both bound to a backingBean. 

This  is the jsf code:
 



The code from the bean is also pretty straight forward:

The Case for migrating your Oracle Forms applications to Formspider

We’ve been getting a lot of inquiries asking whether we have a tool that will automatically convert Oracle Forms applications to Formspider.
We don’t have an automatic converter. We don’t view this as a disadvantage at all. We are solving the modernization problem with a different approach:
Formspider does not automatically converts your Forms applications to web apps but it converts your Forms developers to first rate web developers.
We think this approach produces the (more...)

Here I'm going to describe how you could authenticate with BPM from ADF through a proxy user, on top you could apply only business user name, password will not be required.

There is API method available - authenticateOnBehalf(context, userName), you must have a valid connection context created and with authenticateOnBehalf (more...)

MAF 2.0 : Loading Images in a Background Process – Part I

Images are heavily used in Mobile apps. For instance a list that contains employees usually shows the images of these employees. This works well when you have a WIFI connection, but what if you are using slower connections ? If you look at a mobile twitter app you will see that, depending on connectivity, images are loaded instantaneously or delayed. In this post I explain how you can load the

But that’s impossible, or finding out that the JIT has broken your code.

Every now and then you look at some code and think that it cannot be possibly be wrong. Once you have ruled out a simple programmer screw up / enemy action in code (Make sure you read Java Puzzlers or similar) or a concurrency issue (Read Java Concurrency or go on Dr Heniz excellent course) you should sit back and take a few days and then starting thinking about whether the JDK is indeed (more...)
