ireport iterating through data Collection and accesing fields

I want to create simple report with jasper iReport. I don't know how to iterate thought object C fields. For that purpose I created sub report. Example of my classes:

public class D {
    private A a;
    private B b;
    private ArrayList<C> c;
    //getters setters
}

public class C {
   int id;    
   String name;
   // getters setters
}

In main report I declared :

<subreport>
.....
<dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{c})]]></dataSourceExpression>
<subreportExpression><![CDATA["C:\\path\\report1_subreport2.jasper"]]></subreportExpression>
</subreport>

In sub report :

<field name="c" class="java.util.Collections"/>

My question: how to access fields of class C?

I tried to change class java.util.Collections to C, to create fields with names of C but nothing helps.

When you define the fields, do it as follows

<field name="c.id" class="java.lang.String"/>

<field name="c.name" class="java.lang.String"/>

where c is the object and, id and name are the fields of class C. Also make changes in the class as in the code.
