Upgrade your Groovy Scripts in Mule with DSLDs

Posted by Edward McLoughlin on 29 September 2015

The groovy script transformer component is a very powerful piece of Mule. I use it for almost every message transformation that I need to make. Its XML and JSON libraries reduce message format conversion down to little more than building a map, while closures give you some powerful processing tools for handling complex data structures.

Advanced File Handling in Mule

Posted by Robert Valk on 15 June 2015

With all the drag-and-drop goodness of AnyPoint Studio these days, it’s easy to forget that under the hood Mule ESB remains a very powerful, configurable and extendible framework. This power comes in handy when you’re faced with demanding file processing requirements in advance of Mule’s out-of-the-box functionality.

LDAP Security in Mule

Posted by Devendra Khanolkar on 26 February 2015

On a recent client engagement we adopted SOAP over HTTP as our preferred communication channel for Web Service consumers. Since the transport protocol was HTTP, our next requirement was to setup HTTP Basic Authentication and role-based authorization. We tend to prefer simpler transport-level authentication over WS-Security which is overkill for most situations.

Developing Bulk APIs with Mule, RAML and APIKit

Posted by Robert Valk on 02 December 2014

Recently we’ve been writing quite a few ‘bulk’ APIs - where consumers don’t want a single resource, or a screenful of search results but instead need (close to) the entire record set. In this blog we discuss several features of the Mule ESB platform that make is easy to design and implement bulk APIs over a variety of back-end technologies.

Value Cross Referencing in Integration

Posted by Edward McLoughlin on 25 September 2014

In almost every integration project in existence, you’ll find that at some point you need to map one set of representative values to another. It doesn’t take long to think of a few common examples. Lets take two hypothetical systems named Xup and Yonder. How do they each represent countries in addresses?

A Groovy way to implement a JMS Request Response client using Camel

Posted by on 16 September 2014

While working for one particular client we were under the particular constraint of not having access to the JMS management console (in this instance the ActiveMQ Console). So when it came time to test out integration workflows we needed a quick and easy way to call the SOAP over JMS services. The Deloitte Platform Engineering folks are well versed in their Groovy scripting and came up with this awesome Groovy script:

Here at Deloitte Platform Engineering Continuous Delivery has become a central part of the way we work. Naturally, we were very excited by the news that ThoughtWorks – who introduced Continuous Delivery (CD) to the world – have recently open-sourced their CD server software ‘Go’.

Reliable Messaging with Mule ESB and Amazon SQS

Posted by Andy Evans on 19 June 2014

I recently used Mule ESB with Amazon's Simple Queue Service (SQS) as the supporting messaging infrastructure. Whilst I was able to achieve a reliable outcome that satisfied all requirements, there are a number of aspects of SQS that make it different to the typical JMS-based messaging system. In this post I’ll cover these key points of difference and walk through an example of a robust and reliable Mule flow that can be applied to a range of common integration scenarios.

Formatting Dates and Times using XSLT 2.0 and XPath

Posted by on 17 December 2013

A handy addition in XSLT 2.0 is a nice set of date and time format XPath functions. XSLT 1.0 was decidedly lacking in these functions, so you may have used a third-party library such as EXSLT for this purpose. EXSLT offers arithmetic functions on dates and times (still absent in XSLT 2.0) but the XSLT 2.0 offering is perfect for formatting dates and times as strings. It also means that you don't have to worry about importing the third-party library.

Data Mapping with Groovy - Part 1

Posted by on 14 November 2013

ESB services involve working with a variety of different data formats and structures e.g. XML, JSON, CSV, spread sheets, key-value structures. Transformations between XML and other data structures are quite common when it comes to developing an ESB layer. Mule ESB provides a wide range of choices when it comes to scripting and data transformation.  There’s enough choice to satisfy the proclivities of any developer.
