MaintainJ

MaintainJ is an Eclipse plugin that provides a Java reverse engineering tool that generates UML class and sequence diagrams at runtime for a single use case. It lets you know what exactly happens when you run a use case. The sequence diagrams generated are simple to read and explore. The calls can be folded and expanded as necessary to explore what is of interest. The loop calls and recursive calls are removed for a simple and readable sequence diagram. MaintainJ can be used on any Java code or jar files.
