Subreport data source expression

[Asdfghjkl123]

I have problem to display a subreport in a master report. Data sources for both are collections. When I put a subreport element into a master report it's need to define "Connection/data source expression". So I wrote in a text field "new JREmptyDataSource(1)". After this in a pdf appears a null information from a subreport. Please could you help me to write the data source expression?

Subreport data source class looks liki this:

Code:

public class ServiceBean {

    private String name;
    public static List createBeanCollection() {
        List list = new ArrayList();

        ServiceBean serviceBean = new ServiceBean();
        serviceBean.setName("name1"«»);
        list.add(serviceBean);

        ServiceBean serviceBean1 = new ServiceBean();
        serviceBean1.setName("name2"«»);
        list.add(serviceBean1);

        return list;
    }
    public String getName() {
        return name;
    }
    public void setName(final String name) {
        this.name = name;
    }
}

Thanks in advance.

Regards, Denis.

Try something like this.

 

Datasource Expression:

 

new JRBeanCollectionDataSource(ServiceBean.createBeanCollection())

 

Hope this helps.
