Social Coding Resolves JAX-RS and CDI Producer Problem

The inimitable Bruno Borges picked up tweet earlier today commenting on a problem using @Produces with non-CDI libraries with WebLogic Server 12.1.3.

The tweeter put his example up on a github repository to share - quite a nice example of using JAX-RS, CDI integration and of using Arquillian to verify it works correctly.  Ticked a couple of boxes for what I've been looking at lately

Using the WebLogic Embedded EJB Container

The WebLogic Server 12.1.3 EJB Developers Guide was recently updated to note that the embedded EJB container can be used by adding a reference to weblogic.jar to the CLASSPATH when the EJB client is being executed.

https://docs.oracle.com/middleware/1213/wls/EJBAD/embedejb.htm#EJBAD1403

This is very convenient since it enables the WebLogic Server embedded EJB container to used by simply adding weblogic.jar to the classpath when running the client:

Exclude folders from you subversion update

Working in an IT project, means working with version control. A lot of times, this means subversion in combination with Tortoise SVN. In bigger projects it sometimes happens there are folders in the tree structure that you are not really interested in. 
It is a good things, that you can exclude this folders from your update, so you don’t get distracted by de commits done on folders you don’t care about.

Hows many steps did I walk yesterday: using Cordova, HealthKit, and JavaScript, and a handful of Promises

As people who know me might know I have been playing around with various wearables for some years now, starting with a Nike Fuel Band, and also trying out products from Misfit and UP along the way. I have mostly just watched with interest as my exercise levels, and indeed sleep now we have a little one in the house, has gone up and down over time.

More recently with the arrival of HealthKit there (more...)

MAF 2.1 – Debugger Improvements and Mobile REST Client

Today I'm going to blog the next step in the same series - MAF client consuming REST service exposed from Oracle Mobile Suite ESB. I'm going to highlight improvements in debugging process for MAF, provided with the latest 2.1 release. I had couple of challenges implementing and mapping programmatic MAF client for REST service, all these were (more...)

I'm looking at the most popular content on my blog from time to time and try to address your needs the best. So, reading my blog is the one way for my fellow readers to drive the content. Another way is to reach out to me in comments or via email. For today, I am going to revamp my JDBC Realm example with Primefaces and update it to latest WildFly server.

WebLogic Maven Plugin – Simplest Example

I've seen a question or two in recent days on how to configure the weblogic maven plugin.

The official documentation is extensive ... but could be considered TL;DR for a quick bootstrapping on how to use it.

As a late friday afternoon exercise I just pushed out an example of a very simple project that uses the weblogic-maven-plugin to deploy a web module.  It's almost the simplest configuration that can be done of the plugin (more...)

Updated WebLogic Server 12.1.3 Developer Zip Distribution

We've just pushed out an update to the WebLogic Server 12.1.3 Developer Zip distribution containing the bug fixes from a recent PSU (patch set update).

This is great for developers since it maintains the high quality of the developer zip distribution and the convenience it provides - avoids reverting to the generic installer to then enable the application of patch set updates.  For development use only.

How To Add New Operation in Oracle Mobile Suite Service Bus REST Service

I will use sample app from my previous blog post as the basis - Oracle Mobile Suite Service Bus REST and ADF BC SOAP. I was describing there the main steps in defining transformation from SOAP WS based on ADF BC to the REST WS interface. I will dive a little bit deeper into the same topic and will explain how to add new operation to the REST WS interface.

Using Code Snippets in JDeveloper

In JDeveloper, it can be helpful to set up code snippets to be of easy use later. Personally I use this mainly to set up code snippets for demo purposes and this is rather easy to set up.
First of all, if not already open, open your Components Window in JDeveloper: 

Now open the file that you want to create the code snippet from, this can be any file in JDeveloper as example I opened (more...)

You’re Cleverer Than You Think

I often train experienced developers in new tools, and I’ve found that most underestimate what they can do – their actual skill level is higher than their own perceived skill level.

Skill development

This is different from new developers, who tend to overestimate their skills.

The reason this happens to most experienced people is the “loss of control” feeling overcomes the feeling of accomplishment. If you are very skilled with one tool, you are acutely aware that (more...)

SSL with WildFly 8 and Undertow

I've been working my way through some security topics along WildFly 8 and stumbled upon some configuration options, that are not very well documented. One of them is the TLS/SSL configuration for the new web-subsystem Undertow. There's plenty of documentation for the older web-subsystem and it is indeed still available to use, but here is the short how-to configure it the new way.

Grails on Openshift

I created a simple Grails application which makes it possible to store client data inside a MySQL database. I created this application since I want to learn more about GORM (Grails Object Relational Mapping).

I already tested the application in the internal server from Grails, but I wanted to deploy it to a remote server. So I created a development account on Openshift and there I created the following server:

showPopupBehavior align property examples

I always struggle to understand the official descriptions for the align attribute of the af:showPopupBehavior tag. A picture is worth a thousands words so I just created screenshots of all the possible values:

afterStart: The popup appears underneath the element with the popup's upper-left corner aligned with the lower-left corner of the element. The left edges of the element and the popup are aligned


afterEnd: The popup appears underneath the element with the (more...)
