Generate SQL query with library

[darko.jankovic_1]

Is it possible to generate the SQL query that will be executed when generating the report?
I found a way to get the query with the parameters, like this

final JasperReport report = JasperCompileManager.compileReport(layoutStream);String query = report.getQuery().getText();[/code]

What I want to achieve is to get the query with the parameter values inserted. Is there a way to achieve this?
I'm using version 6.1.0 but I can probably upgrade if it's necessary.

So this should be possible. 
Define a string parameter in your jrxml. Set the given parameters as your datasource query and set the query string on run time.

Here is an example of a jrxml. I am running on a oracle db datasource, but hard seleting via dual. 
So in your java code via the jasper java api just figure out to set the given parameter.
