If you can run Eclipse I guess you can also run JasperAssistant.

Re: Page Break

You can either configure a group to create a page break at each grouping expression change, or you can use the page break element to control page break manually.

Re: Dynamic Query to create JRXML file

Hi,
You need to write data source class in that class you will execute the query and get that result to pass to array list. Then Pass that array list to JRBeanCollectionDataSource.
JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(arraylist);

JasperReports will look for an image in several locations using this order:
* Interpret the location as remote URL (ex: http://etc)
* Interpret the location as file location on disk
* Interpret the location as classpath resource

JRXML DTD problems (markup attribute of textElement)

Anthony Quinn — Mon, 03 Nov 2008 11:12:00 -0000

Hi everyone, I'm new to Jasper and I'm having a bit of trouble with compiling my report.

I've designed my report in Jasper Assistant which works fine when I preview it, but when I come to compile and generate the report programmatically I hit exceptions with the XML.

Here is the code I'm using to compile the report:

try {
jasperReport = JasperCompileManager.compileReport("reports/Merchant Report.jrxml");
jasperPrint = JasperFillManager.fillReport(jasperReport, model, conn);
JasperExportManager.exportReportToPdfFile(jasperPrint, "reports/Merchant Report.jrxml");
} catch (JRException e) {
logger.error(e.getMessage(), e);
result = false;
}

It complains that I do not have the markup attribute declared for textElement which I do and even then I've checked the DTD the report is using and it says it's and optional element.

Here is the exception:

log4j:WARN No appenders could be found for logger (org.apache.commons.digester.Digester.sax).
log4j:WARN Please initialize the log4j system properly.
2008-11-03 11:03:04,434 ERROR ( ReportTask.java:83)-org.xml.sax.SAXParseException: Attribute "markup" must be declared for element type "textElement".

Any ideas?

how can I use eclipse/jasperassistant from a thumb drive

markroberg — Sun, 02 Nov 2008 02:15:00 -0000

need a portable development environment. I deal with a few customers that will not permit me to connect my notebook computer to their network. They will permit me to run anything I can from a thumb drive. I currently am not using u3 thrumb drives but have figured out how to run oracle's sqldeveloper and dbvisualizer. I need to be able to do the same with jasperassistant.

Someone out there must have done this??

Re: Tiny fonts in jasperassistent on Windows

Peter Severin — Thu, 30 Oct 2008 10:49:00 -0000

Simon,

Are you able to reproduce the problem on other Windows machines? Send me one of your jrxml files and I will try to reproduce the problem.

Tiny fonts in jasperassistent on Windows

Simon — Thu, 30 Oct 2008 09:08:00 -0000

We have previously been happily developing with jasperassistant 2.x using Eclipse on Linux. Just recently we upgraded to Eclipse 3.4.1 + jasperassistant 3.0 on Linux, and all works fine. But one developer has also started working on Windows 2008 server, and there the fonts used to render text in the jasperassistant "design" and "preview" pages are tiny (too small to read), for exactly the same .jrxml files.

Modifying the jasper report settings to change the font from "sansserif" to "Times New Roman" makes the text readable again on that windows platform - but we don't want to change the font for each report. And certainly there should be a "sansserif" font available on Windows platforms!

I don't know whether the problem is Windows config, Eclipse config or jasperassistant config.

Has anyone else seen this problem?

We are trying to image in a report created from our web application. It won't display. I have tried various directories. Where is the default location it will look?

I tried UNC //server/folder/image.jpg
package name com/company/a/b/c/image.jpg
just image.jpg

Hi Can I append results of multiple calls to fillreport into a single report ??

pass a Custom datasource

Antonis — Tue, 21 Oct 2008 10:27:00 -0000

Hello,
I am trying to pass an object ("myListArray" with one field "testArrayA", which is a list) to iReport.
But,I cannot pass a custom structure through the create function in the myListArrayDatasource class :
public JRDataSource create(JasperReport report, ArrayList list)
throws JRException {
return new JRBeanCollectionDataSource(list);
}

If I try to change it to :
public JRDataSource create(JasperReport report, myListArray list)
throws JRException {
return new JRBeanCollectionDataSource(list);
}

it through an error that "the constructor JRBeanCollectionDataSource(myListArray) is undefined".

So, I am forced to let it as an ArrayList constructor , but I am getting the following errors when it executes the fillReport method :

net.sf.jasperreports.engine.JRException: Error retrieving field value from bean : testArrayA

Caused by: java.lang.NoSuchMethodException: Unknown property 'testArrayA'

Can anyone help me with this?

Thank you in advance.

Re: jasperReport subreport inside subreport

Chigozie Damian — Mon, 20 Oct 2008 10:23:00 -0000

Follow these steps
Step 1
======
Create two different reports for both the questions and the answers list.

Step 2
======
Construct JRBeanCollectionDataSource objects for the questions and answers lists. Like this :

<code>
List<Paper> paperList = new ArrayList<Paper>();
paperList.add(this);// ie the paper object

JRDataSource paperDataSrc = new JRBeanCollectionDataSource(paperList);

JRDataSource questionDataSrc = new JRBeanCollectionDataSource(getQuestions());

JRDataSource answerDataSrc = new JRBeanCollectionDataSource(getAnswers());

InputStream mainRptStream = getClass().getResourceAsStream("../masterRpt.jasper");

InputStream answerStream = getClass().getResourceAsStream("../answers.jasper");
InputStream questionStream = getClass().getResourceAsStream("../questions.jasper");

JasperReport mainRpt = (JasperReport) JRLoader.loadObject(mainRptStream );
JasperReport questionSubRpt = (JasperReport) JRLoader.loadObject(questionStream);
JasperReport answerSubRpt= (JasperReport)JRLoader.loadObject(answerStream);

Map<String, Object> main = new HashMap();
main.put("questionDataSrc ", questionDataSrc );
main.put("answerDataSrc ", answerDataSrc );
main.put("questionSubRpt ", questionSubRpt);
main.put("answerSubRpt", answerSubRpt);

Then inside the master report, embedd both the questions and answers subreports in the detail band of the main report.

Configure their dataSourceExpression properties to map to their respective JRDataSource objects.

Configure their subReportExpression properties to map to the respective JasperReport objects

JasperPrint jPrint = JasperFillManager.fillReport(mainRpt , main, new JREmptyDataSource());
JasperExportManager.exportReportToPdfFile(jPrint, "D:/test.pdf");
</code>

I hope it works. All the best.
