The trickle-feed integration pattern
23/9/2007 - 4:33 pm
Posted in AMIS, General, Oracle, SOA & Oracle Fusion Middleware, Technical Architecture | No comments
This pattern was ‘invented’ by our SOA-architects team integrating the Oracle SOA Suite and the Oracle e-Business Suite in an existing IT-landscape.
The trickle-feed integration pattern can be used when
distributed systems integrate with one another by means of asynchronous messaging.
The messages are versioned to each other in such a way that the newest version may
only be [...]
Package java classes (WSIF calls) in BPEL suitcase

Introduction
Is it possible to package java classes which are invoked through WSIF along with the BPEL Suitcase generated by bpelc?
I’ve noticed that when generating and deploying the suitcase using JDeveloper (10.1.3.x) – the class files are compiled to the output directory and packaged in the suitcase, but when I run the same build.xml via Ant [...]

Much has been written on how to trace database sessions through a java application in all sort of different techniques.Since Oracle 10g a new technique is added to the tracing stack: DBMS_MONITOR. This blog briefly describes with code examples how you could use DBMS_MONITOR to trace database sessions via a web application, through a pooled [...]
Solving SOA Suite installation issues

The last months I’ve been a frequent visitor of the SOA Suite forum on OTN. The reason for this is that I’ve been busy getting acquainted with new SOA Suite. And the forum was helpful in resolving some of the problems I’ve encountered during the learning track of this new product and the installation of [...]
Funny ESB?

Hi all,
I’ve used my ESB system – installed on SuSE9, connected to a 10.2 E.E. on the same machine – for a few
months now, so I thought it would be interesting to take a look [...]

Doemscenario voor de toekomst van Java? In five years, Java EE will be the CORBA of the 21st Century. People
will look at it and say, ‘It had its time but nobody uses it any more
because it was too complicated.’

Creating a message based routing service in ESB
7/11/2006 - 7:02 pm
Posted in AMIS, General, Oracle, SOA & Oracle Fusion Middleware | 1 comment
Yesterday I blogged about difficulties in routing messages from an AQ adpater to different outputs using the Oracle ESB (http://technology.amis.nl/blog/?p=1395). I was unable to create a single router that could route incoming messages based on the correlation ID. With help from Dave Berry on the OTN forum, he pointed me to a good ESB sample [...]
Guaranteed delivery not obvious for ESB.

Posted in AMIS, General, Oracle, SOA & Oracle Fusion Middleware | 3 comments
Recently I have made an ESB system based on dequeueing an advanced queue and conditionally forward of the content to different files on the file system. In the development process I ran into some issues which for me raised the question "Are messages processed by the Oracle ESB delivered to the end-point with perfect guaranty?" [...]

Automatic continuous compilation of webforms on linux without X-terminal
In the webforms world you it is not uncommon to compile a webforms application on a linux/unix application server, after you’ve build a forms module on your Window development environment. Modules compiled on Windows typically will not run on another operating system, so the binaries must be [...]
