Collection manipulation

[AshishP Gandhi]

I need to take some records and display it on a jsp...and manipulate them like sorting / pagination
These records come through webservice.

Can you guide how should I go about it?

Can I make a class and get all data in collection and manipulate it the class when jsp page asks for sorting which is a button?

Awaiting replies.

try a JSF dataScroller. it will take you 5 minute to implement.

Hi,

Implementing java.util.Collections is possible in WebServices using @XmlJavaTypeAdapter (JAXB 2.0).
have a look on below link and example
https://jaxb.dev.java.net/guide/XML_layout_and_in_memory_data_layout.html

@XmlRootElement
class ComplexStruct {
@XmlJavaTypeAdapter(value=ArrayListDataAdapter.class)
@XmlElement
ArrayList<Data> dataList;
}

class ArrayListDataAdapter extends XmlAdapter<Data[], ArrayList<Data>> {

@Override
public ArrayList<Data> unmarshal(Data[] objectArray2ArrayList) {
if ( objectArray2ArrayList == null )
return null;

return new ArrayList<Data>(Arrays.asList(objectArray2ArrayList));
}
@Override
public Data[] marshal(ArrayList<Data> arrayList2ObjectArray) {
if ( arrayList2ObjectArray == null )
return null;

Data[] dataArray = new Data[ arrayList2ObjectArray.size() ];
int i=0;
for (Data data : arrayList2ObjectArray) {
dataArray [ i++ ] = data;
}
return dataArray;
}
}

regards,
Surya.
