Parameter values are null before query execution

[kavi_mathi]

I m passing Parameters from first report to the second report  Eg: param1 ,param2. In the second report , some calculations and processes are to be done with the passed parameters param1 ,param2 . These calcuations are to be done before query execution. So in the query , I m using a new parameter $P!{calculate}.  The parameter 'cacluate' calls a java method and takes input as param1 ,param2.But the values of the param1 and param2 are printed as 'null' before query execution . The original value is printed in the fill portion of the report after query execution. 

How to get the value of the parameter before query execution?

Try move $P{calculate} down in list of parameters in iReport(Studio?). The example:
Parameters
param1
param2
calculate

Sometimes order of parameters (variables?) is important

When we try this in the Server , the parameters are not getting passed .

The reason may be I m trying to get hold in the Query Execution itself . But not sure.

Thanks for the suggestion. The order of Parameters are followed .Inspite of that , the parameters are null in the Java method.
