For a start, you can refer to the quickstart examples which are present in the Fuse installation folder. You can try and build those projects. You can also refer to the github repositories, as there are many projects there as well.https://github.com/pchhabra11/Fuse
It is my repository, you will get many other if you just search there.
It is not necessary to use the JBDS, you can use the eclipse as well for the development.
