Is there a way to export a Jasper report in PDF where designated fields can be left editable? I'm using iReport to design the report templates.
It's not possible today. It's an unusual requirement, but it's not unreasonable. It's really not an iReport limitation but rather a JasperReports limitation. If anyone coming to this post in the future would like to have this feature, the best thing to do would be to log it in the Jaspersoft bug tracker.
Two facts:
iText can do it. http://www.geek-tutorials.com/java/itext/itext_acroform_javascript.php#code2src
JasperReports use iText.
Theoretically, JR can do it, but I don't find methods in javadoc, that used parameters.
Maybe anybody know?
No you can't but technically it is not impossible. AFAIK,PDF editable field is specific to PDF format itself, JasperReport API is meant to produce only the commons elements to the major files format like text, tables, shapes, images... The best way to find out the tip, is trying with input text for html format, you know you can have html elements in the jrxml. PDF also support html elements isn't it ?
Added a "net.sf.jasperreports.export.text.isInputForm" to switch text field and static text component to pdf form text fields. Just set this property to "true" on static text or text field. The fix is just using itext's form within jasperreports.
