How about a Security Layer?

I recently had a great discussion with Wendy Nather from the 451 Analyst Group. She had found one of my previous posts on using a service gateway to protect against the OWASP Top 10 and had some follow up questions. I wanted to share some of the discussion as well as her questions because it really got me thinking more about Enterprise application architecture and security.

Beyond the Simple Proxy: Using a Service Gateway to Secure the Extended Enterprise with Bi-Directional Protocol Handling

Large Enterprises face a constant challenge in balancing technology costs with new business goals. Many enterprises have existing business processes bound up in applications that communicate using ‘legacy’ protocols such as FTP and MQ, which were really designed for behind the firewall operation in a trusted network. Given these constraints what’s the best way for a large Enterprise to extend these applications to external customers and partners without relying on an expensive re-engineering effort or concentrating risk in a single vendor?

Applying a Service Gateway architecture to integrating your e-Invoicing

Surfing the Eisbach riverI was recently asked to talk at the European eInvoicing and eBilling conference about better ways to integrate the transfer of e Invoicing and e billing into existing applications and security solutions. By the way, it was held in Munich and, if you go, definitely check out the surfing at the south end of the Englischer Garten.

How to extend XSLT using built in extension functions.

XSLT 2.0 and to some extent 1.0 are powerful languages when it comes to transforming documents and even for performing some tasks. But, as is often the case, to do something odd or unusual can often be impenetrable or just plain difficult.  One of the advantages of using Intel® SOA Expressway is that most of the extension functions we have written to make configuration easier for BPEL based workflow are also available to the XSLT developer.

Practical Application of Data Convergence

A typical Healthcare Information Exchange (HIE) accepts data from an array of disparate sources. Often the data it accepts is semantically and syntactically altered by a providing system to satisfy interfacing requirements. However, there are also cases where data from different sources need to be properly merged before reaching the HIE's interface.

XSLT 2.0: Regular Expression Functions and Instructions

XSLT 2.0: Regular expressions

One of the weaknesses in XSLT 1.0 was the very simple set of string manipulation features. In comparison to many popular programming languages, the string functions lacked one very powerful feature, regular expressions. Intel SOA Expressway actually offers this functionality with extension functions for our customer base. In XSLT 2.0, the XSLT working group plugged this hole for everyone in a couple of ways that we’ll look at in this post.

XSLT 2.0: Sorting

As conformance testing and fixing progresses for the Intel SOA Expressway XSLT 2.0 processor, I’ll continue examining new XSLT 2.0 features. In my previous post, I talked a bit about grouping, which puts items from a sequence into groups by key value or by relative position. With the right input, that might also sort the sequence, but typically that won’t be the result. So in this post I’ll talk about a close relative, sorting.
