If you want to show none of the content of your report when there is no data (no title, headers, footers, etc.) then you should add a noData band to your report and put the message there. Then change the whenNoDataType report parameter to NoDataSection.

From the JasperReports Ultimate Guide:

If the <noData> section is defined in the report template, and if the data source is empty, then the <noData> section will be the only one taken into account at fill time

Example:

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" 
        name="report1" 
        whenNoDataType="NoDataSection">

    <pageHeader>
        <band height="20">
            <staticText>
                <reportElement x="0" y="0" width="100" height="20"/>
                <text><![CDATA[Page Header]]></text>
            </staticText>
        </band>
    </pageHeader>
    <detail>
        <band height="20">
            <staticText>
                <reportElement x="0" y="0" width="100" height="20"/>
                <text><![CDATA[Detail]]></text>
            </staticText>
        </band>
    </detail>
    <pageFooter>
        <band height="20">
            <staticText>
                <reportElement x="0" y="0" width="100" height="20"/>
                <text><![CDATA[Page Footer]]></text>
            </staticText>
        </band>
    </pageFooter>
    <noData>
        <band height="20">
            <staticText>
                <reportElement x="0" y="0" width="555" height="20"/>
                <text><![CDATA[No data found for this request]]></text>
            </staticText>
        </band>
    </noData>
</jasperReport>

There is a property of the template WhenNoDataType.

Just set it to WhenNoDataType: AllSectionsNoDetail.

This will have the template(static fields) but no dynamic data from database.

If you just want to print some message than you will have to change the design up a bit. You would need to place a condition at the beginning of your report to check if data is coming from database, and act accordingly.
