smartGWT: retrieve data from server to populate a listGrid
- by Gabriele
I'm searching a way to populate a ListGrid with an XML response from a server.
This is an example of my server response:
<?xml version="1.0" encoding="UTF-8"?>
<tbody id="tbody">
<tr>
<word>The</word>
<frequence>12</frequence>
</tr>
<tr>
<word>best</word>
<frequence>3</frequence>
</tr>
...
And this is how I can populate the ListGrid using a file (item.xml) where I have saved the xml result:
public class Frequenze extends DataSource {
private static Frequenze instance = null;
public static Frequenze getInstance()
{
if (instance == null) {
instance = new Frequenze("frequence");
}
return instance;
}
public Frequenze(String id)
{
setID(id);
setRecordXPath("//tr");
DataSourceTextField wordField = new DataSourceTextField("word", "Word");
wordField.setRequired(true);
DataSourceIntegerField frequenceField = new DataSourceIntegerField("frequence", "Frequence");
frequenceField.setRequired(true);
setFields(wordField, frequenceField);
setDataURL("ds/item.xml");
setClientOnly(true);
}
}
Now I want not to use the file, but I'm searching a way to retrieve the data directly from the server. Anyone know how I get this?
