Error evaluating expression JRBeanCollectionDS

[antoniocv]

Hi:

I am using Dynamique Jasper (DJ) to generata dynamique reports thought I think my problem is with JasperReports (JR) since the DJ interface seems to call directly the JR methods.

My code is below and I am trying to use a bean with String, Date and Long objects as the data for the report. I pass the data bean list to the JRBeanCollectionDataSource and this data source is passed to the DJ method to generate the JasperPrint.

After the generateJasperPrint() invoke, this exception is thrown:

net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression : Source text : $F{fec}

If I remove the Date and Long object, it runs ok, but with these types the above exception occurs. I have tried also with JRMapCollectionDataSource but the same problem occurs with these object types.

Does anybody knows some issues with these objetc types I need to take in account? Can anybody hel me?

I am using JR 2.0.5 an DJ 3.0

Thanks a lot in advance,

Antonio.

 

Code:

ArrayList listaBeans = new ArrayList();listaBeans.add(new BeanDatos("Antonio", "Crespo", "Velasco", "03855305", new Date(), Long.getLong("1000")));listaBeans.add(new BeanDatos("Antonio", "Crespo", "Velasco", "03855305", new Date(), Long.getLong("2000")));listaBeans.add(new BeanDatos("Antonio", "Crespo", "Velasco", "03855305", new Date(), Long.getLong("3000")));listaBeans.add(new BeanDatos("Antonio", "Crespo", "Velasco", "03855305", new Date(), Long.getLong("4000")));listaBeans.add(new BeanDatos("Antonio", "Crespo", "Velasco", "03855305", new Date(), Long.getLong("5000")));          jasperPrint = DynamicJasperHelper.generateJasperPrint(dynamicReport, new ClassicLayoutManager(), new JRBeanCollectionDataSource(listaBeans), new HashMap());

I have been doing more tests in order to discover the problem and I have more information.

If I remove the Date objet of the bean, it seems to run but the Long object is not printed in the report (see file attached).

That doesn't sound like a valid argument to me.  I can directly call java.lang.Integer.parseInt("foo") and it doesn't mean that the resulting exception is caused by a problem in the JDK.

I think you should post this question on the DynamicJasper forums.  On this forum there might not be many people that know how DynamicJasper works, so you might not get the help you need unless you can reproduce the same problem directly with JR.

Lucian

Hello lucianc:

Thanks for your reply and help and sorry for posting here instead of Dynamique Jasper forum.

You are rigth, I should post my problem in Dynamique Jasper forum but I thought it could be a Jasper problem. I have replicated my test with Jasper only code and I don't have the ClassCastException with the java.util.Date objet, but the report print all no-String atributes with null values.

Maybe if I solve this problem with Jasper I could solve in Dynamique and we will not post any other things but jasper in this forum

Find attached my jrxml and my pdf.

Thanks a lot,

Antonio

In my previous post there was an error and I was not passing any date.

I have change the code and the Date is printed in the report but not the Long.

Find included the new code

Any ideas?

Thanks again

Antonio.

[lucianc]

Long.getLong("300") returns null (unless you have system property named "300"), see the Javadoc.  You probably want Long.valueOf("300").

HTH,

Upsss.

Problem solved.

Thanks again for your time.
