How to make editable PDF fields in a Jasper report

Two facts:

1. iText can do it. http://www.geek-tutorials.com/java/itext/itext_acroform_javascript.php#code2src

2. JasperReports use iText.

Theoretically, JR can do it, but I don't find methods in javadoc, that used parameters.

Maybe anybody know?

Editable inputs are possible with newer releases of JasperReports.

Example:

<reportElement positionType="Float" mode="Opaque" x="250" y="0" width="200" height="50">
  <property name="net.sf.jasperreports.export.pdf.field.type" value="Text"/>
  <property name="net.sf.jasperreports.export.pdf.field.text.multiline" value="true"/>
  <property name="net.sf.jasperreports.print.keep.full.text" value="true"/>
  <propertyExpression name="net.sf.jasperreports.export.pdf.field.value">"This\nis a multi\nline text inside a single line text field."</propertyExpression>
</reportElement>

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.
