If Actuate 8 can export its reports to an XML file, you could develop an XSL template that transforms the report to a .jrxml
format suitable for reading by iReport and JasperReports.
If Actuate 8 only exports its report format in a proprietary binary format, you are out of luck (without a significant time invested in translating from binary to .jrxml
). At that point, I would lodge a feature request with Actuate to create an XML data format for their report files.
I doubt everything can translate perfectly from Actuate 8 to JasperReports, though, so you might lose a few details the translation.
