Last Updated on 30/05/2021 by Patryk Bandurski It is always desirable to reuse as much code as possible. We can do the same regarding DataWeave transformations and custom functions. In this article, I will describe how to reuse code in the newest DataWeave using modules. For those working with DataWeave 1.0, I will describe how…
Last Updated on 25/08/2022 by Patryk Bandurski During transformation to JSON, we often do not want null properties. It is easy to remove them, by just using the skipNullOn attribute. However, for empty objects, it is not that trivial, especially when you have to deal with many such cases within one transformation. In this article,…
Last Updated on 04/05/2021 by Patryk Bandurski Content Enricher is definitely a useful integration pattern. It allows easily enrich message content with new data gathered from external resources. In the vast majority of Mule’s apps, I have been using the Message Enricher Component. Today I will point main differences in Mule 3.x and Mule 4.x…
In this brief article I will describe the problem and solution that I have lately faced. As it is a good practice not to hard-code connection data I have extracted them to external file called connection.properties. I did not expect to receive an error something like $[smtp.host]. I did not know what it can means. Below I have described what it is.
After I have passed mule Integration Professional exam I got a lot of questions from the community. What materials did I use? What are the main points to learn. What to expect on the exam. I have decided to share some of my experience with the certification. In this blog’s post you can find all materials that I have used.
Raml 1.0 introduces new concept called DataType. This fragment is used to declare type in a separate yaml file. This is not just a simplification of JSON schema to conform raml/yaml. It also brings simple improvements and syntax sugar that allows to write types in more concise form. And therefore more readable. In this article we will look at how to define own data types and reuse them in API and its implementation
Last Updated on 03/05/2021 by Patryk Bandurski In the last article, I have described a nuisance with casting to an integer value. This time we will look at huge numbers and their formatting. In addition, I will mention scientific notation. All these topics are around the number format used by the DataWeave engine. So let’s…
Last Updated on 26/07/2022 by Patryk Bandurski Errors occur all the time. All you can do is implement error handling. In this article, I will describe how to use the introduced abstraction layer in the exceptions area. Before Mule 4, developers only could access raw Java exceptions as Mule is a Java-based ESB. This led…
Anyone who has designed RESTfull API appreciate API Kit Router available in Mule. It not only generates flows based on API definition but also route and validate messages. Our flows looks more concise and easy to read. This feature is available for both Community and Enterprise editions. For SOAP Web Services SOAP Router is available. However this time this utility works only for Enterprise Edition. Some time ago I developed a couple of services on Mule Community Edition. All services have WSDL contracts and I must say that when I now think about the implementation I would appreciate such router. So I have decided to write something similar that would work for Mule CE.
Last Updated on 03/05/2021 by Patryk Bandurski There are times when you need to get one particular element from an array, but not based on the index. This item needs to fulfill some requirements like equality and so on. In order to perform that task filter selector ‘?‘ was introduced. This is applicable for both…
