This plug-in requires WebSphere Application Server. Most of the steps include the Command Path parameter, which specifies the folder that contains the wsadmin command-line tool. Therefore, you must run the steps on an environment that includes an installation of WebSphere Application Server.
You can also use this plug-in to import information about a WebSphere Application Server cell as a resource. Then, you can add the cell to an environment. See Creating an environment from a WebSphere Application Server cell.
