JasperSoft uses a repository data source to store its profile data and this repository database is an integral part of the JasperSoft application. Without it, JasperSoft will not function. If making any changes to this repository data source such as its database server (Postgres, MySQL, SQL, Oracle, etc), configuration (port), and/or access credential (name and password), changes are required to the application context to reflect the repository data source changes.
