CSV DataSource

Problem with the Custom DataSource

I read the tutorial: 4.4 Implementing a new custom datasource and tried to run this tutorial on my computer.

I design the .jrxml or xml file with iReport

I put the .jasper, .jrxml and test.csv on the same folder an the CSVDatasourceTestFactory.java, ,JRCSVDataSource.java .class, in teh folder itbusinesslogicireportconnection.

Then I adapt the compiler directory.

Then selected the menu BUIL->compile all, then Built-> run with active connection(The connection test was successful).

The result is:

Compiling to file... C:Dokumente und EinstellungenAAZIGE.ireportbspDataSourcemyDataSource. -> C:Dokumente und EinstellungenAAZIGE.ireportbspDataSourceuntitled_report_1.java

Errors compiling C:Dokumente und EinstellungenAAZIGE.ireportbspDataSourcemyDataSource.!

Hi

Thank you for your help. But could you provide me with an example, So I can see what am I doing wrong. Because I have provide fields but how would it know COLUMN_1 vs COLUMN_2 vs COLUMN_3 and etc. Thanks for your time and response again.
