create jrxml file at run time and modify at run time

Question

Hi

I have a requirement to develop custom reports where we already have some reoprts developed using JasperReports using iReport tool. Now the requirement is to modify those reports design at run time. I should use those existing jrxml files and save as to new report then change the design at run time. Also I should see those newly created reports whenever I want.

I have gone through the Jasper API and Dynamic Reports where we can create the reports dynamically at run time but we can't save the design (like JRXML).

I am looking for any other JRXML design API to create and modify and save the Jasper Reports at run time.

I appreciate if any one can help me.

Thanks in Advance Srinivas

Answer 1

First thing you will need to draw a flow chart of how you want to do things.

For example, if the report already exists, and you want it as is, what will you do? In case you want to modify it a little, do you want to save as jrxml and compile each time? Or do you want to compile to jasper, store on local storage then populate later.

It seems you want to build a reporting engine and answering all those questions is basic. In that case here is something to start from. Find a factory called DocumentBuilderFactory which will help you parse the XML into DOM object, modify then save it.

Here is a good tutorial on using it

It seems DynamicJasper can do this.
