The documentation of software is an everyday business of a software developer and engineer. Especially for integration scenarios a diagram on the flow of a message through the system or the whole landscape is an essential illustration. Fortunately there are standardised messaging patterns which can be used. Unfortunately, however, there is no tool which can create such visualizations out of the box directly of source code. In this article we will have a look at Apache Camel and how it is possible to get a graphical representation of an integration route. We will also discuss about debugging it, as some tools have the feature to do this.
