WSO2 Tutorial - BPS

In this tutorial of the WSO2 path I'm working with the BPS version 3.0.0 and WSO2 Developer Studio version 3.0.0.

The objective of this tutorial is to show how to implement a simple process and deploy it in the BPS.

I'll use here a standard default installation of the server (no external DB for process management and so on)

TEIID 8.1 tutorial - Part 15 - Support Update

In this new tutorial of the TEIID series I'll show how to update the original table from the VDB view.

Usually when operating with TEIID designer the "orange" view model proposes just to read/select from the source table.

To be able to Update/Insert/Delete from the original table we must enable the "Support Update" checkbox as shown in the figure below.

In the video I'll show the whole procedure.

GeoServer 2.2.5 + JBoss 7.1.1 and Oracle

As I posted some time ago, I'm using GeoServer version 2.2.5 on a JBoss 7.1.1 installation; now I'm working with an Oracle Database so I've added the Oracle extension. And added it in the "$WAR/WEB-INF/lib/" the jar that is downloaded as a separate package (mind to download the same version for the GeoServer you are using).

I had this problem accessing oracle tables:

The problem is due to a classloading mechanism of the AS.

TEIID 8.1 tutorial - Part 10 - TEIID SOAP service + WSO2 + SoapUI

In this tutorial I'll be publishing the book SOAP web service using the API manager from WSO2.

To demonstrate that it works I'll be using as usual SoapUI

The API Manager is composed of two components the Publisher and the Store.

Obviously I need to start from the publisher and create the API: you ger the WSDL endpoint from the JBoss consolle in the webservices TAB.

The API start as CREATED so I need to set into PUBLISHED state.

The API is ready to be used, so is turn of the Store where is quite easy to subscribe to the API.
The main idea is that I'm a developer that uses some of the API published on the Store and I can have different applications that make use of the API and can register to use them with different "Tier" levels that means how much requests I can issue in a given time.
