A theme is the set of all CSS (Cascading Style Sheets) and associated images that define the appearance of the user interface. Themes are stored in the Themes folder in the repository, with special menus on theme folders for activating, uploading, and downloading a theme. You can store any number of themes in the repository and switch among them, to change the UI's appearance.

For multi-organization deployments, administrators can set the theme individually for each organization, or rely on theme inheritance to use the same theme everywhere without needing to set it explicitly. Theme inheritance supports a mix of explicit and inherited settings, so that you can override any setting or image in a local organization, but inherit the rest of the theme from the parent or system-wide theme.

In some cases, the set of files in the default theme changes between versions. Custom themes developed in for earlier version may need to be updated to work with theupdated theme. For more information, see the TIBCO JasperReports Server Upgrade Guide.
