Java collection as a Table data source?? [message #114226]

Hi!!

I'd like to use my Java object collection as a data source in a table.
Is it possible to do ??

I can send my collection to the report as a scriptableJavaObject but how
should I read it in my report ??

Regards, Wojtas

Hello,
in your java code, you must pass your collection as a
scriptableJavaObject.
in your report, you create a datasource with a script.
then you create a dataset which use the new datasource.
then you link your table with the new dataset.
then open your dataset in code view :
in open method :
var iterate = myCollection.iterator();
in fetch method :
if (!iterate .hasNext()) return false;
var person = new
Packages.com.my.package.Person(iteration.next());
row["name"] = person.getName();
row["phone"] = person.getPhone();
return true;

(replace Person by your class in your Collection).

You must have in your class Person a constructor like this:
public Personn(String name, String phone) {
this.name = name ....
}

if you don't understand something, ask it.

Bye

thanks too, i try and that does work :

in my webapp :
task.addScriptableJavaObject("myCollectionObjectReport",myCollection);

my dataset :
in open method :

iterate = myCollectionObjectReport.iterator();
(and not with "var" like : var iterate =
myCollectionObjectReport.iterator();
why ? i don't know :D)

in fetch method :

if (!iterate.hasNext()) return false;
myObject = iterate.next();
row["myObject_code"] = myObject.getCode();
row["myObject_libelle"] = myObject.getLibelle();
return true;

(and not with "var" and "Packages.XX.XX" like : var myObject = new
Packages.com.my.package.MyObject (iteration.next());
why ? i don't know :D)

and my table link with the new dataset.

Regards.
Denis.

I don't understand in my case it doesn't work without
Packages.com.my.package.MyObject (iteration.next());

For 'var' key word, i have already the probleme in some case.

Which version of birt do you use ?

Regards.
