I am getting an error "unknown hyperlink target 0" when I try to run a Jasper Report.

Question

I recently noticed that something was wrong with a Jasper Report I was running, so I downloaded the latest version of iReports, edited the .jrxml file with iReports, and compiled it to generate a new .jasper file. Now, when I try to run the report, I get a weird error "unknown hyperlink target 0". What's going on?

Answer 1

I don't know if this is the only reason this error would happen, but in my case, I compiled the report with iReport-3.7.3, but the software I am using to run the report uses jasperreports-3.6.2.jar. Once I replaced the jar file with jasperreports-3.7.3.jar, the report ran happily. It turned out to be a version incompatibility.
