While creating new reports i follow the below steps:
1. create jrxml file using ireport.
2. compile the file to produce .jasper file by passing required parameters.
3. display the report in desired format html. pdf, etc.

So basically i have the report template/design in jrxml file. Depending on the requirement/parameters i populate the values.

Now i want an advanced report. where the report column needs to get build dynamically and the value for those columns will also be queried dynamically.

For example:
A report that displays the number of products available in each branchs.
So the branchs can vary over time.

Product chennai Bangalore pune ......... Total
abc 1 5 4 10
vnn 3 1 1 5
Total 4 6 5 15

Inorder to do it we need to build the report dynamically.
Any one can provide me with some solutions.

Some solution which i read from forums are
1. generate the xml dynamically and produce a .jasper file.
2. generate jasperreports using API

Can you provide me with some simple examnples.


Awaiting for immediate response. As i need to a immediate solution.
