View Full Version : Can JFreeReport do this?

10-14-2006, 02:10 PM
I have been playing around with different reporting engines and design tools. What I have settled on is BIRT because I can do the following things:

- changing attributes of report cells depending on complex rules

Really what I want to do is to colour a cell depending on the value of another value from the result set. From discussions here I understand that it is possible to extend JFreeReport to do this or to use the BeanShell to do dynamic colouring and attribute setting. So I guess I answered this part.

- a separate summary table, a separate crosstab table, and a main itemized listing table

As I understand it the current release of JFreeReport only has one table in the report, so having a separate summary table and crosstab table is not possible. Is this correct? Or is it just a limitation of the design tools which show a single simple table.

- is it possible to do crosstabbing?

Even in BIRT you can only do static crosstabbing, which is very tedious to set up each cell, but at least it is possible.

Hey there,

Great questions, and we have answers, and a couple of questions too!

a- For traffic lighting, absolutely - that's actually built in. Check out the ElementTrafficLightFunction.

b- For crosstabbing, the Pentaho Platform has several solutions for that. First, we have the CrosstabComponent which will take data from one column, and turn it into multiple columns (i.e. a crosstab). For dynamically creating a JFreeReport definition, you can use template components and even Javascript components to accomplish this. For more details, see the following tech tip:
