Problem: Jasper Server Excel Export Configuration Doesn't Work

1. Environment

Jasper Server 5.6.2 Community Edition.

2. Problem

I tried to modify the default excel export configuration, revised the setting in /WEB-INF/applicationContext.xml as follows:

<bean id="xlsExportParameters" class="com.jaspersoft.jasperserver.api.engine.jasperreports.common.XlsExportParametersBean">
        <property name="detectCellType" value="true"/>
        <property name="onePagePerSheet" value="false"/>
        <property name="removeEmptySpaceBetweenRows" value="false"/>
        <property name="removeEmptySpaceBetweenColumns" value="false"/>
        <property name="whitePageBackground" value="false"/>
        <property name="ignoreGraphics" value="false"/>
        <property name="collapseRowSpan" value="true"/>
        <property name="ignoreCellBorder" value="false"/>
        <property name="fontSizeFixEnabled" value="true"/>
        <property name="maximumRowsPerSheet" value="0"/>
        <property name="xlsFormatPatternsMap" ref="formatPatternsMap"/>
    </bean>
    
    <bean id="odsExportParameters" class="com.jaspersoft.jasperserver.api.engine.jasperreports.common.OdsExportParametersBean" parent="xlsExportParameters">
    </bean>

And I also cleaned the Tomcat's temp folder and work folder before starting Tomcat Server.

However, it doesn't work! Frustrating!

3. Workaround

In short, make empty rows not empty, just looks like empty :)
