Blank report?

2003-10-05 04:11

Hey All!

 

Came across a strange anomaly that I wanted to post here:

 

If a report is compiled that doesn't have a query associated with it. If I pass in a java.sql.Connection object, then a blank report is generated!

 

So I was able to solve it by:

 

JRQuery query = report.getQuery();

 

if (query == null) {

JasperManager.fillReportToFile(report,

tempFile.getAbsolutePath(), getReportParameters(),

new JREmptyDataSource());

} else {

JasperManager.fillReportToFile(report,

tempFile.getAbsolutePath(), getReportParameters(),

con.getConnection());

}

 

However, it just seemed really strange that the report filler would care about the datasource if there was no query. If it's a bug, I wanted to point it out (JR 0.5.0), and if not, hopefully it'll help somebody else working with it!

 

Thanks for a fine library!

Hi,

 

This is the intended behavior.

Why would someone expect the reporting engine

to iterate over some records when a connection

object was supplied, but inside the report there

is no query.

 

However, you might consider using

whenNoDataType="AllSectionsNoDetail" for your

report, if you want the engine to generate something

even when there are no records in the data source.

 

Thank you,

Teodor
