“JSON Web Token (JWT) is a JSON-based open standard (RFC 7519) for creating access tokens that assert some number of claims. For example, a server could generate a token that has the claim “logged in as admin” and provide that to a client. The client could then use that token to prove that it is logged in as admin. The tokens are signed by the server’s key, so the client Continue ReadingSOA Suite 12C: Generating a JSON Web Token (JWT) in OSB→
A while back I did a post about the business rule engine. See here. In the end of the post I added some considerations. One was the very annoying performance of the business rule component in JDev when using decision tables. If you were editing them, the memory usage started growing and after 5 minutes JDev would crash. Also editing large decision tables was very slow. The worst part back Continue ReadingSOA Suite 12C : Patch to fix the JDev business rule component performance→
Retrieving data from a back-end system or executing something in a business rule engine can cost quite some time. When we build services we want to strife for performance but sometimes you make services which you just can’t make any faster. One thing to keep in mind is that it is possible to cache in SOA Suite using the coherence adapter. For example retrieving data from a back-end system in Continue ReadingUsing the Coherence Adapter in SOA Suite 12C→
You can write your own XPath lib in Java to make certain things easier and re-usable. For an example see here. From the documentation of 12C, nothing indicated that things would have been changed so I stuck in an old library and restarted JDev. When I opened the xslt mapper, I didn’t see my functions under User Defined. This made me wonder if maybe something did have changed. Last week Continue ReadingCustom 11G XPath function not showing up in JDeveloper 12C→
A few days ago, we needed a some business functionality to validate an IBAN account number. You can use inline Java in your BPEL process but there are more elegant ways as you don’t want to pollute your orchestration layer with business functionality. An nice and elegant way, in my opinion, is the use of the Spring component. By using this component you can expose a Java bean as simple Continue ReadingSOA Suite 12C: Simple example of using the Spring component→
One of the components of the Oracle SOA Suite is the Business Rule Engine. The Oracle Business Rules engine….and I quote ‘allows the externalization of specific business logic and parameters. Business analysts can easily define, update, and manage key parameters and decision trees that are likely to change based on business evolution (for instance discount levels, credit rates, etc.) without having to involve IT and developers. This all sounds pretty Continue ReadingOFM 12C: An example of the Business Rule Engine with Java facts→
Continuous Integration has been a big deal in Java land for many years now. We all want to integrate and test our software as soon as possible and preferably automated. With the new 12C edition, we can now build OSB projects and SOA composites using Maven. That is great because Maven has all sorts of nice features out of the box and available plugins. In this blog post I will Continue ReadingContinuous Integration using Oracle SOA Suite 12C: Part 1→
