данный вопрос решил использованием JRDataSource
например
| Код |
public class ExampleDataSource implements JRDataSource {
private int m_nIdx;
private ArrayList<SampleObject> v = new ArrayList<SampleObject>();
public ExampleDataSource() {
v.add(new SampleObject("user1","passwd1"));
v.add(new SampleObject("user2","passwd2"));
v.add(new SampleObject("user3","passwd3"));
v.add(new SampleObject("user4","passwd4"));
v.add(new SampleObject("user5","passwd5"));
v.add(new SampleObject("user6","passwd6"));
v.add(new SampleObject("user7","passwd7"));
v.add(new SampleObject("user8","passwd8"));
v.add(new SampleObject("user9","passwd9"));
v.add(new SampleObject("user10","passwd10"));
m_nIdx = -1;
}
//public ExampleDataSource(Vector<AccountCashFlow> v)
//{
// this.v=v;
//}
public Object getFieldValue(JRField field) throws JRException {
System.out.println("get field(ExampleDataSource): " + field.getName());
Object o = null;
String sName = field.getName();
SampleObject obj = v.get(m_nIdx);
System.out.println("obj " + obj);
if (obj == null)
return null;
if (sName.equals("userName"))
o = obj.getUserName();
else if (sName.equals("passWord"))
o = obj.getPassWord();
System.out.println("returns " + o);
return o;
}
public boolean next() throws JRException {
m_nIdx++;
return (m_nIdx < 10);
}
}

Есть некоторые проблемки, есть кто нить кто работал с JasperReport? |
