Review of Oracle Service Bus 11g Development Cookbook (Packt Publishing) by Edwin Biemond, Guido Schmutz, Eric Elzinga et. al.
3Recently I gained access to an electronic copy of the just released Oracle Service Bus 11g Development Cookbook, written by five authors – all experts on OSB and three personal acquaintances of mine. I was very interested in learning about the final result after hearing many intermediate comments during the writing process as well as reading the occasional remark on Twitter. Knowing Guido, Eric and Edwin and assuming the same expert level for the other two authors, I anticipated a very interesting read.
Below I will share my impressions from browsing through this solid 500+ page volume. Note: the homepage for the book can be found here: http://www.packtpub.com/oracle-service-bus-11g-development-cookbook/book .
Jouw toekomst als Oracle professional – AMIS !!EXTRA!! informatieavond over jouw ontwikkelingspad
0Als je dit leest en je bent Oracle professional – ontwikkelaar of administrator – is de kans groot dat je jouw carriere bent gestart in de jaren ’90, in het tijdperk van Oracle7, Oracle Forms en Client/Server applicaties – net voor de opkomst van Java, internet, mobiel en SOA. Misschien ligt je start daar nog wel voor en misschien ben je van een tikje later. Maar in elk geval: je hebt een solide fundament en al vele jaren ervaring in Oracle technologie.
Nu is het 2012. En de afgelopen jaren is de technologie in hoog tempo ontwikkeld. Web 2.0 applicaties en multi-tier architecturen dienden zich aan en SOA, Service Bus en BPM zijn opgekomen. Java is overal – en HTML 5 staat op het punt om Flash en Silverlight te verdringen, in desktop browsers en in mobiele devices. Eindgebruikers worden mondiger en veel-eisender en real-time, push-enabled, BI-gedreven dashboards en multi-channel takenlijsten worden in snel itererende agile-projecten gerealiseerd.
Oracle 11g Database doet alle simpele DBA taken zelf – en de uitdaging voor de Database Administrator is verschoven naar groter en interessanter, zeker als 24/7 beschikbaarheid, virtualisatie en de cloud als infrastructuur opduiken. More >
Business Validation in Oracle SOA Suite 11g using Schematron
4In a previous post I’ve explained the Schematron standard, how it works and how to use it. In the Oracle SOA Suite you can ‘Validate Semantic’ on the input (request) of a routing rule in a Mediator component by selecting a Schematron file. This is the Schemtron xml file in which you define your validation rules. The SOA Suite takes care of applying them on the request by executing the double transformation. However, to be able to get the Schematron file working you need to declare the namespaces of the input message and rewrite a report rule to an assert rule. In this post I will show you how to do this with the same business rules (so the same Schematron rules and Schematron file) as the last example in a previous blog explaining Schematron. (more…)
Difficulties with a more complex Business Rule Engine in Oracle SOA Suite
0In my previous post I’ve shown how to create a composite in the Oracle SOA Suite with a simple decision table in a Business Rule Engine component. For that post I had used quite a simple data model resulting in a small xml/xsd tree. For our project I wanted to repeat the exercise with the real data model, so a larger xml tree defined by multiple imported xsd files. Unfortunately it wasn’t as easy as I hoped for. In this second blog post about the Business Rule Engine I’ll show you about the difficulties I had and how I’ve solved them. (more…)
Cookbook creating Business Rule Engine with a simple Decision Table in Oracle SOA Suite
5For educational purposes I’ve created a cookbook in powerpoint format on how to create a simple decision table in Oracle SOA Suite with a Business Rule engine. To share this I’ve uploaded it to slideshare and post it here in the Amis blog as well. (more…)
How to call a webservice directly from Java (without webservice library)
7In this blog I will show you how you can call a webservice programmatically in Java without using a webservice library like JAX-WS or Apache Axis. Normally you would use of course a webservice library, but in some cases this can be useful and quick; for example when you have problems generating a client proxy with a webservice library or if you only need some small specific parts of the SOAP response XML tree.  It shows that a SOAP call is just XML over HTTP, from a plain piece of Java code. Then, I will show you an example how you can use this and make your own servlet webservice-tester like a simple SoapUI in JDeveloper 11.1.1.3.
