A wrapper component for JasperReport. Depending on your browser, clicking the "Get Report" button would either embed a report in the browser or a native dialog would be invoked to prompt you to save the file.
This demo shows following file type reports :

• PDF
• HTML
• Word (RTF)
• Excel
• Excel (JXL)
• CSV
• OpenOffice

<div apply="org.zkoss.bind.BindComposer"
