Hi,

Check the "datasource" sample for details about
how to use this type of data source.

The reporting engine is only interested in "pure data"
and this is why it only needs a TableModel,
not the entire JTable.
However, JTable has a getModel() method that
you could use.

I hope this helps.

Hi,

If you want to use the JRTableModelDataSource
to wrap a TableModel object, you have to make
sure you have declared a report field for each
column in the TableModel, having the same name.

If not, you could still access the colmun values by
index, if you declare report fields like:
COLUMN_1, COLUMN_5 or COLUMN_100

I hope this helps.

Hi,

It means (in your case) that even if you declared
corresponding report fields for each table column,
their type does not seem to correspond.
It's like a type mismatch between the TableModel
columns and the report fields.

I hope this helps.

Hi,

If this is the exact case, then you should
pay attention to the "class" attribute that you
choose for each report field you declare in the
report.
It has to correspond exactly to the type of the
values found in the corresponding TableModel
column.

I hope this helps.
