Beginner needs help

2004-10-21 06:40

Hello,

 

I am a beginner with Jasper and I have problems with parameters, fields and variables. I have read the tutorials and did not find the answer to my question.

 

I have added a parameter (?_1?) in my jasper report and I am trying to compile my .xml into a .jasper and the compiler says it cannot find the parameter. I intended to give jasper the parameter at runtime with the fillreport function.

 

Where do I need to declare the parameter in order to avoid the compile-time problem?

 

Here is the java class that exports the report into a pdf:

 

public class MonTestJasperDeux {

 

public static void main(String[] args) throws Exception {

Map map = new Hashtable();

map.put("_1", "un");

map.put("_2", "deux");

map.put("_3", "trois");

 

List list = new ArrayList();

list.add("toto");

list.add("titi");

 

 

JRDataSource data = new JRBeanCollectionDataSource (list);

 

 

InputStream jasperFile = MonTestJasperDeux.class.getResourceAsStream("JasperReportUn.jasper");

JasperPrint jPrint = JasperFillManager.fillReport(jasperFile, map, data);

JasperExportManager.exportReportToPdfFile(jPrint, "D:\DocsJulienMartin\dev\TestUnJasper\TestJasper\testDeux.pdf");

 

 

 

}

 

}

 

 

Here is my design:

Hi Julien,

 

In your XMl jasper file your must declare your parameters as <parameter>...</parameter> not as <variable>..</variable>

Variable are used for report local calculation.

 

Try to use an editor (JasperAssistant for eclipse or iReport), it will help you to avoid this kind of mistake.

 

Regards,

 

Benjamin

Hi Julien,

 

In your Java class you never compile the template in order to

transform jrxml file to jasper file.

Caution, in your template one variable and one parameter have the same name "_1".
