jasper reports - How to pass parameter value in JasperReport from JSP or Java code?

I have successfully created a report and successfully exported to HTML and PDF. However it is a static report. I have a query as:

select * from personal where id= 'val' 

I want to send this parameter "val" from Java/JSP at runtime. How to do this ?

Create a Map containing parameters and put parameters as key value pair.

Map parametersMap = new HashMap();  
parametersMap.put("id",7);

When generating Jasper Report from JSP:

JasperPrint jasperPrint = JasperFillManager.fillReport(
jasperReport, parametersMap, jdbcConnection);

where the keys in the parametersMap shoud be excatly the same as the parameters defined in your report template.

So, Declare the parameter in your report template (jrxml):

<parameter name="id" class="java.lang.Integer"/>

Pass parameter in query in Jasper Report

select * from personal where id= $P{id}
