Creating password-protected reports with Windward.
At this time, this is not fully supported by Windward Reports.
One option (external to the Windward report engine) is to serve the report in a password protected zip file.
Another option for PDF reports is to require a password to view the report. Again this can be done using an external PDF.
If you're using the engine, you can use library.ProcessPdf.setOwnerPassword() and setUserPassword(). Also look at setSecurity().
