Subreport problems

[maalto]

Hi all,

I am trying and trying and now I seem to be totally lost in this. How to make and understand a subreport.

Could somebody please explain it to me.

I have tried in all different ways, but none has succeded. The most simple way I would think it could have worked was a simple product list from Northwind database (MS-sql2000). I create the subreport and it's working fine. I create the master report and include the subreport into it and also define the "Use connection expression" as $P{REPORT_CONNECTION} and the "Subreport expression" as "D:\rep\t\products.jasper", where I have the .jasper compiled file for the subreport. Still when I run the master I get "The document has no pages", no data seems to be transferred via the subreport ?

What am doing wrong, missunderstanding ?

 

Thanks in advance, Mikael

What is your Subreport Expression Class? Did you try

 

D:/reptproducts.jasper

 

in you Subreport expression?

Sorry I misspelled a bit:

Subreport expression: "D:\reptproducts.jasper"

as java.lang.String class

Does your sub report have any parameters? Are you passing the parameters from the main report?

hi - I was just through this process as well.

 

First of all you need to use the forward slash. also these ".jasper" files are saved at the root of location where JasperSoft has been installed. Liek for me I had to use:

 

"C:/Program Files/JasperSoft/iReport-2.0.2/report_name.jasper"

 

Hope this helps!
