Add client certificate for outgoing OSB call

Posted on by — 4 Comments ↓

Simple use case……you want to connect to a customer system over the internet. The customers system has an API but requires 2-way SSL. This means we have to send a client certificate along to make sure the SSL handshake can be completed. If your server has already a server certificate installed, it will send this one along by default but the customers system won’t accept it as it is different Continue ReadingAdd client certificate for outgoing OSB call→

Custom 11G XPath function not showing up in JDeveloper 12C

Posted on by — Leave a reply

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→

OFM 12C: An example of the Business Rule Engine with Java facts

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→

CI

In the part 1 I have shown how to setup a simple CI environment and how to build a Service Bus project using Maven. In this part I will try to make a release pipeline which builds, deploys, tests, packages and release a whole service using Jenkins and if all successful and finally install the artifact in Nexus. Lets start where we left of. Startup Tomcat and log into Jenkins. Continue ReadingContinuous Integration using Oracle SOA Suite 12C: Part 2. Building a SB and SOA project using maven and the MDS→

Creating a template in Oracle Service Bus 12C

In this article I will show how to use the new templating functionality in Oracle Service Bus 12C. When building a lot of services through different projects, you will always duplicate certain functionality such as Logging, Validation etc… All conform your current development rules and guidelines of the project. This means tedious copying and pasting of certain pieces of code and the old OEPE IDE isn’t always precise with that. Continue ReadingCreating a template in Oracle Service Bus 12C→

Oracle released their new 12C edition of Oracle Fusion Middleware so lets have a look at some of the changes. We are going to make a simple Service Bus project which will take two currencies as input and will return the exchange rate. I installed locally Weblogic 12C and created a base domain. For a brief description how to install SOA Suite 12C see here. After you have installed weblogic, Continue ReadingBuilding a simple service using Oracle Service Bus 12C→

Synchronous BPEL process with a wait activity fails with a timeout

Posted on by — 6 Comments ↓
OFM

Recently we had a timing issue in our project. We were processing certain events and one event got processed before another one which caused a problem. A quick fix seemed possible by adding a Wait activity in our BPEL process which got processed too quickly. We added the Wait and set it to 2 seconds. We deployed it, ran our unit test again but it seemed to ignore the 2 Continue ReadingSynchronous BPEL process with a wait activity fails with a timeout→

Creating a custom XPath function for the XSLT mapper in the SOA Suite

Posted on by — 1 Comment ↓

Sometimes the default XSLT-mapper in the SOA Suite just is not enough. You want a little bit more or you want something that is re-usable for other components. The answer lies in writing your own XPath function. The first thing we need is to create a jar file which contains our functionality. Say we want a function which creates a displayname based on a few parameters. We will use Maven Continue ReadingCreating a custom XPath function for the XSLT mapper in the SOA Suite→

Using JDeveloper to deploy to weblogic over SSL

Posted on by — 1 Comment ↓

When you start working with the SOA Suite 11G the server has a default keystore set. Connecting to this setup over HTTPS usually doesn’t give any problem as the CA’s used are generally trusted by default by the JDK used. One of the things you maybe are going to encounter when you equip your server with a genuin certificate with CA’s in the chain which are not trusted by default, Continue ReadingUsing JDeveloper to deploy to weblogic over SSL→
