Fusion Middleware 11gR1 – Patch Set 5 is available (at last) – First impressions
0It had been announced at Oracle Open World 2011 and sort of promised for December 2011 – a promise or at least a suggestion reiterated in early December even. But for whatever reason, it slipped – not shipped – and Christmas break that perfect time of the year for playing with new software came and went. Now at last, it has arrived. As of midnight CET on 22nd February, PS5 (11.1.1.6) was published on OTN and eDelivery (https://edelivery.oracle.com/EPD/Download/get_form?egroup_aru_number=11493752) for download.
One of the reasons for the delay was the certification of FMW 11gR1 PS5 with Fusion Applications that was done over the last few months. Apart from the additional wait time (that is now over), this is quite good and important news: when Fusion Applications certifies software components, they put those components through very rigorous and extensive tests. Additionally, when Fusion Applications adopt a specific release – even a PS release – it makes that release more important to Oracle. So we now know that PS 5 has both been tested to the max and is of strategic importance to Fusion Applications and thereby to Oracle. Adopting PS5 for us mere mortals is therefore a safe bet – More >
Developing and deploying Java Embedding activity in BPEL 2.0 in SOA Suite 11g calling a custom Java Class that has dependencies on 3rd party libraries
0Java Embedded activity can call a custom Java class that relies on 3rd party Java libraries. This means that a lot of existing functionality from the Java open source community is at the disposal of the BPEL developer. This article shows a simple example of developing and deploying a BPEL process that uses Java Embedded Activity that calls a custom Java Class that uses Apache HttpClient to make Http POST calls. The article demonstrates how to develop the BPEL process, the Java Embedded activity, Java Class and how to deploy the SOA Composite application. It also presents the results of running the composite application.
Introduction of BPEL 2.0 forEach activity – valuable loop and standard based successor to FlowN
1BPEL 2.0 introduced the forEach activity – similar to for [-loop] found in many programming languages. Oracle SOA Suite 11g adopted BPEL 2.0, first in run time (PS2) and later in Design Time (JDeveloper) as well (PS3 an beyond). For BPEL processes created using BPEL 2.0, forEach is a looping mechanism – similar to repeatUntil and while – and also the successor to the proprietary Oracle extension to BPEL 1.x called FlowN. In that latter capacity, forEach is the activity that enables parallelism in BPEL processes to a dynamic degree.
The well known Flow activity also supports parallelism – but only for a static number of branches, known at design time. FlowN (1.x) and forEach (2.0) add the ability to execute a scope a dynamic number of times, determined at run time.
For example when an operation needs to be performed on multiple elements in a collection, such as all order lines in an order or all persons in a travel booking, forEach is valuable – especially when it makes sense to perform the operation on multiple elements at the same time.
Note however that parallelism in BPEL is a relative concept: a single BPEL process instance is never operated on in more than one JVM thread, so More >
Keeping your process clean: Hiding technology complexity behind a service
0This blog will explain how you could abstract technology behind a service so your main process will be kept clean of all kind of technology pollution like exception handling, technology adapters and correlation. (more…)

Batch Aggregation of files in BPEL process instances based on correlation
2Remco is an interesting guy with unexpected ideas springing from a creative brain. He can make life interesting, challenging and puzzling. This time he had another interesting challenge – not all that weird to be honest. The challenge in short was:
Our invoicing system produces files that contain one or more invoice entries. Every entry describes an invoice for a certain company we do business with. There can be multiple invoice entries for the same company. The objective is to aggregate together all invoice entries for a company – potentially from many different file. For each invoice entry – some special processing involving service calls is required. Once all entries for a company have been collected and aggregated, some additional action is required – for example recording the company invoice aggregate in a database or in a file and call a webservice to perform additional processing. The files with invoices are produced over a period of a couple of hours. It is important that the processes performing the aggregation are reliable – they should not lose any entries.
The specific question we investigated is: can we solve this puzzle using Oracle SOA Suite 11g? And an early More >
