Jasper report for the data which is not in databas

[rsathish_gandhi]

Hi,

I'm not having some values in database....That values are calculated in java method itself...

If I want to show that value in report means, Shall I Pass this as parameter?

If So, How can I pass the dynamic parameters? else,

               I stored that values in ArrayList... The size of the arraylist is not constant...How can I pass? How can assign parameter name?

See that code

Code:

public void orgInquireListReport(String contentType, String filename)throws  JRException, SQLException{        System.out.println("ContentType:"+contentType);        System.out.println("filename:"+filename);        String file=getClientLogoName();               String logopath=path+file;           Map map = new HashMap();               JRDataSource simpleDS;        Util util = new Util();               JRBeanCollectionDataSource jrbds = new JRBeanCollectionDataSource(this.getShowPayClient());            List m1=new ArrayList();            m1.add(1);            m2.add(2);               try {            util.GenerateReport("D:/docs/OrgInquire.jrxml", m1, jrbds, contentType, filename);        } catch (IOException e) {            // TODO Auto-generated catch block            System.out.println("Error in IOException");            e.printStackTrace();        } catch (Exception e) {            // TODO Auto-generated catch block            System.out.println("Error in Exception");            e.printStackTrace();                   }    }    is it possible?Please help me?

yes, you can. JasperReports APIs provide a way to pass an arbitrary number of parameters to the report using an hashmap, all the parameters must be defined in the report with name and type.
This allows you to create a "parameter of parameters" creating a parameter called for instance myParametersArray of type ArrayList.
