Part of the Puzzle: Oracle XMLDB NFS Functionality

This story is long overdue and no its NOT about the Oracle Database 11g Database File System (DBFS). Its about an “undocumented” NFS functionality that, maybe someday, will be serviced by the XMLDB XDB Protocol Adapter. This post is “long overdue” because the actual attempts to try to figure it out were done during the bank holidays between X-mas and new year 2009.

So what is it all about. I once discovered in the Oracle 11gR1 documentation a small entry in the xmlconfig.xsd XML Schema regarding NFS elements that look like that they are or will be used for enabling NFS functionality based on the Oracle XMLDB Protocol Server architecture. In those days, when Oracle 11gR1 was just of the shelve, I made a few attempts, based on the xdbconfig.xsd XML Schema to adjust the corresponding xdbconfig.xml file that controls the XDB Protocol Server functionality, to see what would happen. At that time I only was able to get this far (see the picture) and I promised myself that I should look deeper into it trying to figure out if I could get it working and/or what the concepts were that made it tick in the XMLDB architecture but somewhere down the line I just didn’t come to it and it got More >

Leveraging RESTful Services from Java applications using Jersey (Introduction)

While researching for the Oracle SOA Suite 11g Handbook, I wanted to take a quick look at REST(ful) WebServices and see how those can be integrated into the SCA based SOA Composite Applications that we create with the Oracle SOA Suite. Currently, it does not have the HTTP binding that the 10.1.3 release of the SOA Suite used to have. So what are the alternatives? But first, how does one call a simple HTTP only (no SOAP/WS*) service from a piece of Java code? With as little programming and as much framework lifting as possible.

One of the frameworks available for RESTful operations is Jersey – a framework that should be more REST aware than plain HTTP communication oriented libraries like Apache HTTP Client, as well as offer some support for typical formats used in RESTful interactions, such as JSON, XML, RSS, CSV. So let’s create the simples Java application consuming a RESTful service – the Google Translation service – using the Jersey library.
