 Hi , 

Lets suppose if your java Bean , Accounts.java , contain the following properties

Private String fName;

Private String lName;

Private List <BankAccount> bAccounts ;  

 

And BankAccount.java looks like following

private String bankId;

private String branch ; 

 

==================== iReport ====================

 

1) Create a Master Report , Supply the query

2 ) Declare fNname(String) , lName (String) , bAccounts (Object)

3) Drag fName and lName in the Header of the report 

4) In Detail band , create another subreport and pass bAccounts  as a datasource using the following expression

<dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{bAccounts})]]></dataSourceExpression>

 5) Now , in the sub report , declare the fields  ie bankId(String) and branch(String)

6) Drag Drop the fields in detail bank of  Sub report

Hopefully , this will solve your purpose.'

Thank you so much Ankushchhabra. this is what i am looking for. Really thanks. But still I have some doubt. in your explanation you said  "1) Create a Master Report , Supply the query"      I cannot pass a query to the main report. All the data that my main report needs will be coming from a bean like "Accounts.java" I have to pass this bean to the main report in order to fill it. How can i pass this bean to the main report. which data source is suitable. when i check the API i found 2 data sources and both of them take collection and array. I am little confused. I am also new. kindly bear with me. Thanks in advance
