I am posting my detail Section, which has only 1 field. When an output file is created every line has an extra blank line... The content of field 'tranLine' are shorter than the width. <detail> <band height="20" isSplitAllowed="false"> <textField isBlankWhenNull="true"> <reportElement x="0" y="0" width="1250" height="20" isRemoveLineWhenBlank="true"/> <textElement> <font size="14"/> </textElement> <textFieldExpression class="java.lang.String"><![CDATA[$F{tranLine}]]></textFieldExpression> </textField> </band> </detail> Here is my output...
