Getting report name from jasperrepots

[hq4ever]

Hello

 

I'm new to jasper and java as a whole.

I would like to know how I can get access to the jasperreport object from within the jrxml file?

 

I would like to print the name I'm giving to the report.

 

 

 

Thank's for your help guys, happy reporting to us all.

There is no (built-in) way to do that. You can post a feature request here.

Here's a kludge to get the objectname:

 

Make a variable $V{tester}

[initial value expression]

this.getClass().getName().substring(0,this.getClass().getName().lastIndexOf('_'))

 

[Variable Expression]

$V{tester}.substring(0,$V{tester}.lastIndexOf('_'))

 

then drop a textfield onto your report

[textfield expression]

$V{tester}.substring(0,$V{tester}.lastIndexOf('_'))

Just pass the name in as a parameter, and set the parameter to have a default value of the name you assign to the report.

 

 

Edit: As an example:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!-- Created using JasperAssistant (http://www.jasperassistant.com) -->
<!DOCTYPE jasperReport PUBLIC "-//JasperReports//DTD Report Design//EN" "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd">

<jasperReport name="Unnamed" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="30" bottomMargin="30">
	<property name="com.jasperassistant.designer.Grid" value="false"/>
	<property name="com.jasperassistant.designer.SnapToGrid" value="false"/>
	<property name="com.jasperassistant.designer.GridWidth" value="12"/>
	<property name="com.jasperassistant.designer.GridHeight" value="12"/>
	<parameter name="REPORT_NAME" class="java.lang.String" isForPrompting="false">
		<defaultValueExpression><![CDATA["My Sample Report"]]></defaultValueExpression>
	</parameter>
	<detail>
		<band height="100">
			<textField>
				<reportElement x="40" y="9" width="132" height="20"/>
				<textElement/>
				<textFieldExpression class="java.lang.String"><![CDATA[$P{REPORT_NAME}]]></textFieldExpression>
			</textField>
		</band>
	</detail>
</jasperReport>
