Question

public void openReport() {

    try {
        HashMap params = new HashMap();
        params.put("aapor", 19);

        JasperReport jasperReport1 = JasperCompileManager.compileReport("C:/Users/emidemi.emidemi-PC/Documents/NetBeansProjects/FleetManager/src/FleetManager/newReport5.jasper");
        JasperPrint jasperPrint1 = JasperFillManager.fillReport(jasperReport1, params, conn.getConn());

        JRViewer viewer = new JRViewer(jasperPrint1);

    } catch (Exception e) {
        System.out.println(e.getMessage());
    }
}

Above is my script.

This is my error:

com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: Invalid byte 1 of 1-byte UTF-8 sequence.
BUILD SUCCESSFUL (total time: 7 seconds)

Does anyone know why this is occurring and how to fix it?

Answer 1

It’s a problem with the character codification. Have you tried changing the encoding line at the beginning of the report?

i.e. for central european alphabet, change:

<?xml version="1.0" encoding="UTF-8"?>

by

<?xml version="1.0" encoding="CP1250"?>

You have a list of different character encoding standards here:

Hope it works
