Monitoring DevOps Style With WildFly 9 And Jolokia

DevOps is among the hottest topic these days. And the wide range of topics around it makes it hard to actually find a complete description or something that covers everything on a decent granularity. One thing is for sure: One of the most important parts is to deliver the correct metrics and and information for monitoring of the application.

Java EE and JMX
The standard way of monitoring Java EE servers is JMX. This is (more...)

Using JRE 1.8 for the Liberty Buildpack in Bluemix

The latest Liberty biuldpack update now adds the ability to switch to JRE 1.8 runtime. Given I am now switching to JDK 1.8 for all my projects this has come in very handy, and of course Spring Boot favors JDK 1.8 as well. The default is still JRE 1.7 so to switch to 1.8 set an ENV variable as follows in your manifest.yml as shown below.



Using JPA And CDI Beans With Camel on WildFly

I didn't really plan for it, but with a conference free month, I had the chance to dig around a little more and show you even more of the Camel on WildFly magic, that the WildFly-Camel subsystem provides.

The Business Background
The demo is derived from one on JBoss Demo-Central by Christina Lin. She demonstrates the use of File and JDBC connectors in Camel and also added the use of Spilt pattern and Exception handling method. (more...)

How to Hide Actions in OBPM 12c Workspace

In this article I explain how to hide the actions in the drop-down in Workspace.

In some situations you may need to hide the actions that are shown in the Actions drop-down in Workspace.

One way to do so is by configuring the access that users with a specific Workspace role have for a specific task (not to be confused with a swim-lane role), by going to the task definition -> Access -> Actions. For (more...)

Auto Refresh for ADF BC Cached LOV

You can configure auto refresh for ADF BC cached LOV and this works out of the box, no special coding is needed. My previous post describes how ADF BC session cached LOV behaves - ADF BC Session Cached LOV - Understanding Expire Time. Auto refresh can be configured for both application and session caching. One important thing - auto refresh doesn't work when ADF BC is configured with disconnected mode (ADF BC Tuning with (more...)

Starting a Process using a Timer with a Duration in Oracle BPM

In this blog article I explain three options to configure a timer start event based upon some configurable duration.

As far as I know firing a timer based on a duration is only applicable in case of a Timer Event Sub-process. Let me know if you think otherwise.

In case of an Event Sub-process the timer starts at the same moment when the process instance starts. There is no way to change it at any (more...)

Sending JMS Messages From WildFly 8 To WebLogic 12 with Camel

System integration is a nice challenge. Especially, when you're looking for communication standards and reliable solutions. In today's microservices world, everybody talks about REST services and http-based protocols. As a matter of fact, this will never be enough for most enterprise projects which typically tend to have a much more complex set of requirements. A reasonable solution is a Java Message Service based integration. And while we're not looking at centralized infrastructures and ESBs anymore, (more...)

ADF BC Session Cached LOV – Understanding Expire Time

ADF BC offers LOV caching feature. There are two caching levels - application and session. With application level enabled, it makes LOV rows available for all users. On contrary for session level LOVs, data is cached for single session only. In this post I will focus on session level LOV's and I'm going to explain when cached data expires and is re-fetched.

You can configure caching level for LOV's in Model.jpx file, open AppModules (more...)

Using Camel Routes In Java EE Components

I've been working with Camel since a while now and I really like it's simplicity. Using it on top of Java EE always was a little bit of a challenge and one of the recent talks I gave about how to do this and the different methods of bootstrapping Camel in Java EE actually proposes to use the WildFly-Camel Subsystem. In an ongoing series I am going to explore the different ways of doing this (more...)

Using a Parallel Gateway without a Merge in OBPM

In this blog article I give a brief explanation regarding some aspect of the behavior of the parallel gateway in Oracle BPM.

For the BPMN modelers among us, I have a small quiz.

Given a process model like this, what would be the behavior of Oracle BPM?

  1. It does not compile because OBPM thinks it is not valid BPMN
  2. The flows with Activity 1 and 2 are merged, the token moves to the End event (more...)

Oracle Process Cloud Service – SOAP Web Service Integration

Oracle Process Cloud ( allows to invoke SOAP services, along with REST services. You can define a library of SOAP services in Oracle Process Cloud application and use them within the process. This helps to integrate with business logic running on premise.

I have implemented regular SOAP service in ADF BC, just to test how it works to invoke it from Process Cloud:

SOAP service method accepts employee ID and checks (more...)

Oracle Process Cloud Service – Consuming ADF BC REST Service in Web Form

With the introduction of Oracle Process Cloud Service ( there is an option to run your business process in the cloud. You can implement very similar things as it is possible with BPM 12c in JDeveloper, but only in the cloud. There is no option to implement human task UI with ADF, it must be done with Web Forms (light UI forms implementation framework). This is disadvantage, as it will require (more...)

ODTUG KScope15: One week in a nutshell

Last week I visited ODTUG KScope15 in Hollywood Florida. In this post I will share my findings and hope that you can benefit from it. My general impression of the conference is that it was to hot for me in Florida. At least to hot for a conference. If you can sit on the beach whole day long, it is a great place to be, but hey, I had to work.... From a content perspective, (more...)

IoT Hackathon Part II : Overview of Grove Pi sensors

This post gives you an Overview of Grove Pi sensors and the fun things that you can do with it. I will add the real content later, but for now we need a placeholder.

IoT Hackathon Part I : Setting up your Raspberry Pi

This post describes how you can setup your Raspberry Pi in order to start working with it. I will add the real content later, but for now we need a placeholder.

Intercepting Table Filter Query and Manipulating VO SQL Statement

I’m going to describe one non declarative use case. Imagine, if there is a table with filter functionality, you may want to intercept filter items and apply the same for another VO. This another VO should be based on the same DB table, so it could apply criteria items against the table.

Sample application -, implements a fragment with table component and a chart. Table component can be filtered, criteria is intercepted (more...)

Groovy Time! How to use XML dateTime and duration in BPM 12c

In this article I show some examples of handling XML dateTime and durations in Groovy in the context of a Oracle BPM 12c application.

Working with dates and durations in Java has always been painful. Mainly because date and time is a complex thing, with different formats and time zones and all, but I sometimes wonder if it has not been made overly complex. Anyway. Working with XML dates is even more complex because the (more...)

Oracle BPEL & BPM 12c Set Flow Instance Title

In this article I describe how to set the instance title for a composite in Oracle BPEL or BPM 12c.

Sometimes little, annoying things that are fixed with a new release can give great joy. With 11g you could set the composite instance title using the (advanced) XPath function setCompositeInstanceTitle(). This helps to find or identify instances in Enterprise Manager. However, for high volume composites you may want to configure in-memory-optimization as well by adding (more...)

ODTUG KScope15: Sunday Symposium

Sunday symposium took of at 8:30. Unfortunately i had to skip the first two session due to some work That had to be done first. The first session I really got to attend was Brian Fry's session on Oracles Developer Cloud Service. JDeveloper, Eclipse or Netbeans was the way you would work with Oracle Developer Cloud. Now there is a new feature (not publicly available) that is a browser based IDE.
