Hi,

 

I'm trying to create a cross tab report with networks in the columns and months (including their years) in the rows.

 

When I try to compile the report, I get the following errors:

 

net.sf.jasperreports.engine.JRException: Report design not valid : 1. Variable not found : networkCount 2. Variable not found : networkCount 3. Variable not found : year_monthCount 4. Variable not found : year_monthCount at net.sf.jasperreports.engine.design.JRAbstractCompiler.verifyDesign(JRAbstractCompiler.java:267) at net.sf.jasperreports.engine.design.JRAbstractCompiler.compileReport(JRAbstractCompiler.java:144) at net.sf.jasperreports.engine.design.JRDefaultCompiler.compileReport(JRDefaultCompiler.java:105) 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:510) at java.lang.Thread.run(Unknown Source)

 

My jrxml is as follows:

I used the cross tab sample in the jasper report codes as a basis, but I'm battling to understand it.

 

Can someone perhaps help?

 

Thanks

networkCount and year_monthCount are report variables, and you can't access them in your crosstab.

 

Your crosstab is intriguing; for instance you define a measure having class="java.lang.String" and calculation="Sum" - are you trying to sum Strings? Go over the crosstab samples again to understand how crosstabs work.

Lucian
