Pass JRDataSource to SubReport

2005-05-24 05:29

How do I do this?

 

I have the the data source set to "Use Connection Expression" : $P{REPORT_CONNECTION}

but I am guessing it should be "Use Data Source Expression", but dont know what to put instead of $P{MyDataource}

 

My datasource is a JRMapCollection:

JasperPrint jasperPrint =

JasperFillManager.fillReport(

jasperReport,

parameters,

new JRMapCollectionDataSource(Arrays.asList(dataMapArray()))

));

I tried that, but get a java.lang.ClassCastException: java.util.HashMap exception.

I defined my parameter in the main report, and the sub reports as java.util.HashMap, but still get the error? Any ideas?

Are you sure, that you have Maps in you collection?

Write here your jrxml, server code and stack trace for error.

Thanks for your help. I am a complete newby when it comes to JasperReports, and your help is greatly appreciated.

 

 

I am using iReport 0.3.2 and JasperReports 0.6.6

 

 

JasperDesign jasperDesign = JRXmlLoader.load("ODSP001.jrxml");

JasperReport jasperReport =

JasperCompileManager.compileReport(jasperDesign);

 

JasperDesign jasperDesignSub = JRXmlLoader.load("ODSPAcceptance.jrxml");

JasperCompileManager.compileReportToFile(jasperDesignSub, "ODSPAcceptance.jasper");

 

 

 

 

// Map SubReport

Map paraSub = new HashMap();

paraSub.put("AcceptanceName","The sub map exceptance name");

paraSub.put("Test","The sub map test value");

 

// Map of parameters passed to the report.

Map parameters = new HashMap();

parameters.put("Title", "ODSP Test Report");

parameters.put("ProgramName", "The Program Name");

parameters.put("dataSourceSub", paraSub);

 

JasperPrint jasperPrint =

JasperFillManager.fillReport(

jasperReport,

parameters,

new JRMapCollectionDataSource(Arrays.asList(dataMapArray()))

);

 

 

 

jrxml for the main form:

RE: Pass JRDataSource to SubReport

2005-05-25 04:06

if you want to use the Parameter as datasource for your subreport, it has to implement JRDataSource ( like JRMapCollection or an own one) and should be defined in the masterreport like that:

 

<parameter name="yourSubreportDataSourceParameter" class="net.sf.jasperreports.engine.data.JRMapCollectionDataSource"/>

 

then you can pass it to your subreport as following:

 

<subreport>

<reportElement .. />

<datasourceExpression>

$P{yourSubreportDataSourceParameter}

</datasourceExpression>

<suportExpression ... > your Subreport </subreportExpression>

</subreport>

RE: Pass JRDataSource to SubReport

In your sub form you have to use not

<parameter name="dataSourceSub" isForPrompting="false" class="net.sf.jasperreports.engine.data.JRMapCollectionDataSource"/>

but

<parameter name="dataSourceSub" isForPrompting="false" class="java.util.Map"/>

This is a reason for your classcastexception.

But i don't find any subreport tags in your code.

 

 

 

 

By: Andreas Icecold - cubcuz

RE: Pass JRDataSource to SubReport

2005-05-25 04:24

your code can?t work

you have to nest a subreport in your mainForm like i wrote before in one of your sections. You have to write your compiled subreport into a file so your mainReport

can load the Object from it.

 

<detail><band height="20">

...

<subreport>...

<subreportExpression>Path to your Report</subreportExpression>

</subreport>

...

</detail>

 

 

in your subreport you have only to define a field to

get the single values of the passed datasource

 

<field name="record" class="java.lang.Object" />

 

then you can work with it in your subreport like

 

<textField>...

<textFieldExpression>$F{record}</textFieldExpression>

</textField>

 

Best you look in the subreport sample

And it works now. I set the properties on the sub report to not use data source or expression.

But the sub report is displayed as a blank page.

you want to display the values of a datasouce of type JRMapCollectionDataSource in your subreport, am i right?

RE: Pass JRDataSource to SubReport

2005-05-25 04:36

Icecold wrote you, but repeate once again:

look in the subreport sample.

It is very simple and all became clear for you.

Define parametersMapExpression, dataSourceExpression

 

 

 

 

By: new2jasper - villihelga

RE: Pass JRDataSource to SubReport

2005-05-25 04:36

Yes.

 

All I get is a blank page. The subreport has static text, and I can't even see that. I must be doing something terribly wrong.

 

 

 

 

By: new2jasper - villihelga

RE: Pass JRDataSource to SubReport

2005-05-25 04:54

I looked at the subform example, but, like all the examples, it uses a JDBC connection to get the data. I am not allowed to access the data directly (J2EE, WSAD, MVC crap)

RE: Pass JRDataSource to SubReport

2005-05-25 05:08

define dataSourceExpression for subreport

 

 

 

 

By: Andreas Icecold - cubcuz

RE: Pass JRDataSource to SubReport

2005-05-25 05:14

so do what i told you, put your datasource ( type JRDataSource) as Parameter to your main report,

add the parameter as dataSourceExpression to the subreport Element nested in your main report.

 

in your subreport define a field to get access to the single records.

 

best you just test the subreport itself without the main report.

 

JasperDesign jasperDesignSub = JRXmlLoader.load("ODSPAcceptance.jrxml");

JasperCompileManager.compileReportToFile(jasperDesignSub, "ODSPAcceptance.jasper");

 

 

Map parameters = new HashMap();

parameters.put("Title", "ODSP Test Report");

parameters.put("ProgramName", "The Program Name");

...

 

JasperPrint jasperPrint =

JasperFillManager.fillReport(

jasperReportSub,

parameters,

new JRMapCollectionDataSource(Arrays.asList(dataMapArray()))

);

 

this should work.

 

with mainreport it would be like that:

 

JasperDesign jasperDesign = JRXmlLoader.load("ODSP001.jrxml");

JasperReport jasperReport =

JasperCompileManager.compileReport(jasperDesign);

 

JasperDesign jasperDesignSub = JRXmlLoader.load("ODSPAcceptance.jrxml");

JasperCompileManager.compileReportToFile(jasperDesignSub, "ODSPAcceptance.jasper");

 

 

 

 

// Map SubReport

Map paraSub = new HashMap();

paraSub.put("AcceptanceName","The sub map exceptance name");

paraSub.put("Test","The sub map test value");

 

// Map of parameters passed to the report.

Map parameters = new HashMap();

parameters.put("Title", "ODSP Test Report");

parameters.put("ProgramName", "The Program Name");

parameters.put("dataSourceSub", new JRMapCollectionDataSource(Arrays.asList(dataMapArray()))

);

 

JasperPrint jasperPrint =

JasperFillManager.fillReport(

jasperReport,

parameters,

new JREmptyDataSource());

 

 

 

 

 

 

By: Andreas Icecold - cubcuz

RE: Pass JRDataSource to SubReport

2005-05-24 06:49

Just use a JREmptyDataSource as datasource for the fillManager and put the datasource for your Subreport into the Parametermap of your masterreport,

then you can?t access to it via $P{parametername}

 

something like that:

Map parameters = new HashMap();

parameters.put("parametername",yourJRMapCollection);

 

asperFillManager.fillReport(

jasperReport,

parameters,

new JREmptyDataSource());

 

Hope i could help you.

Hello,

 

My subreport iterate one time, in next register of master report the subreport not display but exister register for this subreport.

 

I send in parameters, one paremter DATA, DATA is JRBeanCollectionDataSource.

 

"

if (!m.isEmpty()){

JRDataSource dsDetail = new JRBeanCollectionDataSource(m);

map.put("DATA", dsDetail);

} else {

JREmptyDataSource dsDetail = new JREmptyDataSource();

map.put("DATA", dsDetail);

}

"

 

Somebody help me?

 

My subreport not iterate more time!

 

Sorry to my bad english
