java.lang.ClassCastException

2003-03-21 05:56

I'm sorry if this topic was previously posted:

 

I'm trying to print a report that has a column that is a calculated field using a jsp page, ie:

 

select descripcion, count(1) as cantidad from coincidencias inner join estados on (coincidencias.estado = estados.id_estado) group by descripcion

 

I get the following error: java.lang.ClassCastException

at ConsolidadoEstados.evaluate(ConsolidadoEstados.java:129)

at dori.jasper.engine.fill.JRCalculator.evaluate(JRCalculator.java:678)

at dori.jasper.engine.fill.JRCalculator.evaluate(JRCalculator.java:614)

at dori.jasper.engine.fill.JRFillTextField.evaluateText(JRFillTextField.java:342)

at dori.jasper.engine.fill.JRFillTextField.evaluate(JRFillTextField.java:329)

at dori.jasper.engine.fill.JRFillBand.evaluate(JRFillBand.java:360)

 

java -version prints:

java -version

java version "1.4.1_02"

Java 2 Runtime Environment, Standard Edition (build 1.4.1_02-b06)

Java HotSpot Client VM (build 1.4.1_02-b06, mixed mode)

 

TIA

Found a solution.

 

Aparently the calculated field is of type Long, not Integer. I was using postgresql.
