It consists of a repository for storing different kinds of knowledge, as well a web application that allows users to view and update the information in the repository.
You can edit these variables in the properties view see below when selecting the user task node, or the most important properties can also be edited by double-clicking the user task node, after which a custom user task node editor gjide opened, as shown below as well.
It will help first time huide with the following tasks:. Each type of work item can define additional parameters that are jb;m for that type of work. In the demo, and in general, there are three types of persistent entities used by jBPM:. This chapter describes how to define such processes and use them in your application.
