Find problems when you develop: using XRebel with Oracle ADF

Some days before ZeroTurnaround has released XRebel , a new tool to recognized problems in your web applications, when you make your developer test.
This was promising, so I give it a short try for Oracle ADF applications. For this blog I use the Summit ADF application, delivered by Oracle, but I have tried with our own application too. Test is done in JDeveloper 12.1.2.
After the download there are some easy steps of setup to do:

Node Road show recap. When to use and not use node.

First, that node is designed for high concurrency low latency.  In case you didn't know node has 1 execution thread.  

Publish data over REST with Node.js

Of course the best way to expose database data over REST is with Oracle REST Data Services.  If you haven't read over the Statement of Direction, it's worth the couple minutes it takes.  The auto table enablement and filtering is quite nice.

For anyone interested in node.js and oracle, this is a very quick example of publishing the emp table over REST for use by anyone that would prefer REST
