Every now and then you might want to store some configurations in simple configuration files and use them as OSB Resources in pipelines. In most cases OSB functionality is sufficient to fulfil your requirements. However sometimes you might not be able to get to your goal directly. Recently, I had to retrieve a list of all values in a specific domain column within a Domain Value Map (DVM). As DVMs are primarily used to map one domain value to one or multiple other domains, existing DVM functions do not provide the capability to retrieve all values from a domain column. Therefore, I developed a Java Callout to get the desired result. The solution is applicable to all OSB resource types. This blog post presents the basic concepts used to implement a solution.
