WS-Addressing callback interception using Service Bus by Jeroen Ninck

January 12, 2017 Leave a comment

 clip_image002

Maarten Smeets posted a nice article describing asynchronous interaction in BPEL and BPM using WS-Addressing and correlation sets. I wanted to use Service Bus 12c to force the callback to go through a Service Bus proxy instead of going directly to the consumer. This can be useful when the target service should not have the ability to call services outsite of its trusted domain or network.

All sources can be found in my GitHub repository.

WS-Addressing

WS-Addressing provides a way for message routing and correlation using SOAP headers. It is an official specification. Service Bus, SOA Suite, JAX-WS and quite a lot of other frameworks and tools support it one way or the other. There are two versions of WS-Addressing: 200508 and 200408.

In an synchronous interaction the following headers are important:

  • Request:
    • ReplyTo
    • MessageId
  • Callback:
    • RelatesTo

In the request the ReplyTo specifies the address where the reply must be send to (or http://www.w3.org/2005/08/addressing/anonymous if no reply address is specified). The MessageId headers contains a unique id which can be used to to correlate the request to a future callback. In the callback the RelatesTo header contains the original MessageId. There are others headers for example Action which are important, but for creating an asynchronous interaction ReplyTo, MessageId and RelatesTo are all that are required.

SOA Suite 11g and 12c support WS-Addressing (don’t mention SOA Suite 10g…) and provide out of the box correlation support. Using BPEL no code is required to use WS-Addressing for correlation (both as consumer and as producer).

Test scenario

A SOA composite will implement an asynchronous webservice (a fire & forget request followed by a future fire & forget callback). It will be exposed using a Service Bus project which will ‘hide’ the implementation for the outside world. For example the SOA composite might be running in a local domain, while the Service Bus project migt be running in a SOA CS cloud instance. This will allow to SOA composite to only receive traffic from ‘trusted’ networks and the Service Bus will handle all security.

This will be the test setup, where SoapUI will play the external consumer: Read the complete article here.

How to create a SOA 12.2.1 docker image on OracleLinux (Now Oracle Certified) by Fabio Persico

Introduction

What is docker?

Unless you’ve been living without internet access for the last two years, it would be hard not to at least heard of Docker. But, as an emerging technology not everyone has taken the time to work out what Docker is, where it fits in and how it can benefit you.
So, what exactly is Docker? Here’s what Docker themselves describe it as:
Docker is an open platform for developers and sysadmins of distributed applications.
Essentially, Docker is a container based system for your applications. If you’re used to the concept of virtual servers, Docker provides further levels of abstraction for your application. Here’s a visual representation of how it differs:

Rather than just being one part of the puzzle, Docker provides a number of components and tools to assist with the entire lifecycle management of the application. This includes the container environment, image management and orchestration.
Docker started it’s life as an internal project within a hosting company called dotCloud, but quickly took off once they open sourced it in early 2013. Since then, it’s benefited from over 15,000 software commits from over 900 contributors.

Why use Docker?

Now that you have a basic understanding of Docker, there are a number of great reasons to start using it.

  • It’s very fast. Start a Docker container can be complete in as little as 50ms. That’s not a typo, it really can be this quick! This is the advantage of having such high levels of abstraction, you reduce the number of components you need to run. This also means that there’s very little to no overhead in it’s implementation.

We’ve been talking about this for a couple years now, but finally did it. The idea is to take the very popular Open World panel session called “Oracle SOA Suite Tips and Tricks from Oracle Engineering and A-team” and bring this content to a much wider audience via webinar. We tested the waters with the first webinar in Jan, 2016 and it was even more successful than we had hoped.

We are now extending this into a larger series, to promote sharing of knowledge and expertise with the SOA Suite community at large. We have the commitment of the A-team and lots of good content from engineering, partners as well as customers. So, please check out the information below and register for the series. Get the slides here.

Valuable Features:
  • The technology adapters (Database, REST, LDAP, File, many more), which allow easy integration with technologically diverse systems.
  • BPEL and Service Bus, which allow diverse integration patterns to be easily implemented.
  • The extensive Enterprise Manager Fusion Middleware Control which provides management and monitoring capabilities.
  • The high availability features (mostly important for performance and stability).

Since the SOA Suite provides many components, it is an extensive toolkit for a developer, who can, with relatively little coding, quickly achieve complex functionality.

Improvements to My Organization:

We implement SOA Suite at different customers. The product helps them achieve their goals in terms of integration requirements (functional and non-functional). This ranges from service-enabling legacy systems to integrating COTS products in a stable, performant, and manageable way. Currently, I work for a customer that is digitalizing a legal processes. At this customer we implement reusable services and processes used by multiple front- and backend applications. … Read the complete article here.

The integration possibilities with other Oracle Fusion middleware products is the most valuable feature of the SOA Suite solution. By Andreas Chatziantoniou

Valuable Features:

The integration possibilities with other Oracle Fusion middleware products is the most valuable feature of the SOA Suite solution.

Improvements to My Organization:

I’m a contractor, so my client organizations are the ones who benefit from SOA Suite. With it, it’s quite visible the number of both internal and external processes that are more integrated. Another organizational benefit is that less human intervention is required when running the suite of products in SOA.

Room for Improvement:

Although the SOA Suite solutions integrate well with Oracle Fusion middleware products, it lacks similar integration with Enterprise Manager. This is something that, in my experience working with clients, is needed for SOA Suite to be a better product.  Read the complete article here.

Using eBS Adapter in Integration Cloud Service – Part 2: Configure and Test ISG REST Services by Stefan Koser

January 4, 2017 Leave a comment

clip_image002

 

Introduction

Integration Cloud Service (ICS) enables connecting applications in the cloud or on-premise. It also provides an adapter for Oracle eBusiness Suite. This eBS adapter is different than the eBS adapter in SOA Suite – it does not use a database connection. Instead it uses the REST services provided by eBS as part of Integrated SOA Gateway (ISG).

This article describes the steps needed to get eBusiness Suite including ISG REST services ready – either for using it with any REST client or with ICS. ISG requires some additional patches on top of eBS 12.2.4 – this was shown in this first part , see here.

In this second part, we will show how to enable the REST services, how to enable the metadata provider for ICS and test eBS REST services, first from a native REST client (SOAPUI) and then from ICS. All steps except chapter 4 are also relevant if you want to use Oracle eBusiness Suite ISG REST services without ICS.

Chapter 1 – Configure Integrated SOA Gateway (ISG) in eBS 12.2.4

Enabling ASADMIN User with the Integration Administrator Role

We will execute the steps in section 3 of the MOS note:

Log in to Oracle E-Business Suite as a SYSADMIN user and enter the associated password.
Expand the User Management responsibility from the main menu of the Oracle E-Business Suite Home Page.

Click the Users link to open the User Maintenance page (under “Vision Enterprises”)
Enter ‘ASADMIN’ in the User Name field and click Go to retrieve the ‘ASADMIN’ user.

Click the Update icon next to the ASADMIN user to open the Update User window.
Remove the Active To date field and click Apply.

Click the Reset Password icon next to ASADMIN user to open the Reset Password window. Make sure that ASADMIN’s password is at least eight characters long.
Enter new password twice and click Submit.

In the Update User window, click Assign Roles.
In the search window, select Code from the Search By drop-down list and enter “UMX|FND_IREP_ADMIN” in the value text box.
Click Select.
Enter a justification in the Justification field and click Apply. You will see a confirmation message indicating you have successfully assigned the role.

In my case, a warning is displayed (which can be ignored because the server is restarted later anyway):

Updates to Role data will not be visible in the application until the following processes are started : Workflow Background Engine. Read the complete article here.

Enhancing ICS Mappings with Custom Java Classes by Ricardo Ferreira

January 4, 2017 Leave a comment

clip_image002

 

Introduction

One of the most common tasks performed during the creation of integrations in ICS (Integration Cloud Service) is the implementation of mappings. In a nutshell, mappings are the resources that ICS uses to allow messages coming from the configured source application to be sent to the configured target application. Failure in properly defining and configuring these mappings directly impacts how integrations are going to behave while sending messages downstream.

In order to build mappings in ICS, users make use of the mapping editor. The mapping editor allows for the creation of complex XPath expressions via an intuitive drag-and-drop interface. Besides the support for XPath expressions, it is also possible to use built-in XSLT functions available within the Mapping Components section of the mapping editor, as shown in figure 1.

However, it is not uncommon to find situations in which the set of built-in functions is not adequate to perform a specific data handling operation. When that happens, most people using ICS feel they’ve hit a roadblock due to the fact that there is no way to simply add a custom function. While there is always the possibility to open an SR (Service Request) within Oracle and request an enhancement, sometimes this is not possible because the ongoing project requires at least a workaround in order to be able to finish the use case in a timely manner.

This blog is going to show how classes from ICS’s Fusion Middleware foundation can be leveraged to provide custom data handling in mappings. To illustrate this, the following sections will show how to perform Base64 data decoding, using a utility class from the Oracle WebLogic API.

Programming in XLST Directly

In contrast to what many people think, ICS is not a black box. You can access pretty much everything that is generated by ICS when you export the integration, as shown in figure 2. Once you have access to the integration archive file, you can see what ICS generated for you and in case of mappings, even change it. Read the complete article here.
