model - the file for which to create the parameters

mimeType - the MIME type of the file, e.g. "image/png" or "application/pdf".

userPortalContentType - the user portal content contentType of the file, e.g. "form", "tenantResource" or "tenantTemplate".

Returns:

the encoded parameters to serve the file, or null if the parameters could not be created.

getFile

public static org.primefaces.model.StreamedContent getFile(javax.servlet.http.HttpServletRequest request)

Serves a file from a project, client resource, client template or portal entity.

Returns:

the streamed content for the file, or an empty content if the parameters could not be retrieved or were invalid.
