Help on iReport and JRDatasources

2005-09-14 09:55

Hi, im very new at iReport,

I have this problem, I need to use an implementation of JRDatasource, but have no idea what parameter I have to set inside iReport so I can use it, the class is already done and its inside a jar file, I have tried to set the classpath and after that set a Datasource/Connection, but when i try to compile it to a .jasper file it doesnt work, only this shows up:

 

Compiling to file... ./reportePrueba.jasper -> /home/cmi/.javadev/iReport-0.5.1/bin/reportePrueba.java Errors compiling ./reportePrueba.jasper! it.businesslogic.ireport.ReportClassLoader@1423820 net.sf.jasperreports.engine.JRException: Report design not valid : 1. Field not found : getDescripcionBreve at net.sf.jasperreports.engine.design.JRJdtCompiler.compileReport(JRJdtCompiler.java:146) at net.sf.jasperreports.engine.design.JRDefaultCompiler.compileReport(JRDefaultCompiler.java:129) at net.sf.jasperreports.engine.JasperCompileManager.compileReportToFile(JasperCompileManager.java:127) at net.sf.jasperreports.engine.JasperCompileManager.compileReportToFile(JasperCompileManager.java:109) at it.businesslogic.ireport.IReportCompiler.run(IReportCompiler.java:461) at java.lang.Thread.run(Thread.java:595)

 

Im really new at this, if you can try to explain it step by step it will be greatly appreciated

 

Thanks

Gabriel,

 

You have a field object on your report called

 

getDescripcionBreve

 

probally like this $F{getDescripcionBreve} ???

 

but you have not declared this field in the field list. it might be a typo? You should look at some of the examples in the jasperReport zip/distro. They are the best place to start and there is an example for each of the different datasource types.

 

i use jasper 0.6.1. and the path to the example code is

 

jasperreports-0.6.1demosamples

 

luck
