IText is a library that can be used by developers to enhance their web and other applications with PDF functionality. create PDF, fill out PDF forms, examine and manipulate existing PDFs. JasperReports is a Business Intelligence / Reporting tool that uses an old iText version to create reports. It is distributed by JasperSoft / TIBCO. JasperReports only uses a limited part of the complete iText functionality. Creating PDF is just one of many features of JasperReports, and JasperSoft uses iText to implement that feature. Hope this helps
