Java Reference
In-Depth Information
Our first report will display a static String. Its JRXML follows:
<?xml version="1.0"?>
<!DOCTYPE jasperReport
PUBLIC "-//JasperReports//DTD Report Design//EN"
<jasperReport name="FirstReport">
<band height="20">
<reportElement x="20" y="0" width="200" height="20"/>
<text><![CDATA[If you don't see this, it didn't work]]></text>
There are some elements in this JRXML file that we haven't seen before:
<staticText> defines static text that does not depend on any datasources,
variables, parameters, or report expressions.
<reportElement> defines the position and width of the <staticText>
<text> defines the actual static text that is displayed on the report.
We have seen the <band> element in previous examples. The <detail> element can
contain only a single <band> element as its only sub-element. The <band> element
can contain many different elements that can be used to display text, charts, images,
or geometric figures. In this example, it contains a single <staticText> element.
<reportElement> is a required element not only of the
<staticText> element, but also of all sub-elements of
the <band> element. The x and y coordinates defined in
<reportElement> are relative to the <band> element, which
contains its parent element ( <staticText> in this example) .
Previewing the XML Report Template
JasperReports includes a utility that can be used to preview report designs. This
utility makes designing reports much faster, since we can immediately preview a
report design without having to compile or fill it.
