WSO2 ESB 5.0.0: Data Mapper

One of the features i missed within the WSO2 Developer Studio was a data mapper.
We had to write our own XSLT or PayloadFactory within the product.
But everything is going to change with the release of ESB 5.0.0 !

Or is it ? ....

There is a first blog item on the datamapper that i read and tried:
https://nuwanpallewela.wordpress.com/2016/04/10/how-to-use-wso2-data-mapping-mediator-in-esb/

A very good blog indeed. However when i tried the new developer studio, i was somehow disappointed. I am positive about the fact that the Mapper is a real resource (even project) now. But i miss a lot of features (like for example XPath functions, if-then-else-construct, constraints) within the mapper.

As you can see from the picture below, only the following operators are supported:

  • Concat
  • Split
  • LowerCase
  • UpperCase



And when you investigate the generated project files, you will notice that JScript? is generated to do the actual mapping.



So my first impression is disappointed but it is a good start ! Hopefully new features and operations will be added soon, because at the moment i doubt if it is production ready.

But hey that's my opinion ;-)

OSB 10gR3 and SWA and MTOM

This blog is about using soap with attachments and the use of MTOM within the OSB (10gR3). A service is created that accepts a soap with attachment (DocumentService) and translates it to a service that accepts a binary element. MTOM is used for performance reasons for the second. Some notes: * For the use of attachments you need RPC-style document instead of the usual document-style. This due to the fact that the document-style limits a message to a single . * A service can not have both SWA and MTOM within OSB. First a WSDL is setup for the DocumentService: The $attachments variable holds the attachments and the body holds the attachment data. Also other data is stored within the attachment element (see h...

Cloud to Cloud Application Integration

A lot of applications have integration possibilities, so do cloud applications. The question I got from a customer is whether to have a point-to-point integration with Cloud applications or to go through their ESB solution. This blog describes some considerations. Context The customer has a HRM application in which job vacancies are managed. Furthermore that system also handles the full applicant process flow. They also have another cloud application that handles the job vacancies. This application posts the jobs to social sites and other channels to promote the vacancies. Furthermore this application has some intelligence for job seekers to advice some new vacancies based on previous visits or profiles. The job vacancies need to be sent to the Vacancies application and applicant information needs to be sent to the HRM application, when a job seeker actually applies for a job. Furthermore status information about the job application is als...
