variable Columnname as Fieldname

2003-06-26 03:25

Hallo,

 

I am using JTableModel as DataSource for my Subreports. The name of Columns are not static ( it is like xy.getName()).

 

In subreport i use expression like $F(xy.getName()) but there was nothing to see in the generated report file.

 

can anyone help?

 

Thanks,

 

hamza

$F{X} is used to refer to a field that was declared with the name X. You

can't use a variable expression as a field name; it has to be hard-coded.

You can refer to a column with the name:

 

$F{COLUMN_1}

$F{COLUMN_2}

....

 

Thay are special keywords useb by jasperreports in no table header is supply.

For store your column names, usa parameters.
