Hi,

has anybody a more detailed example for scripting a datasource for POJO,
than what is found here
http://www.eclipse.org/birt/wiki/index.php?n=FAQ.DataAccess
?

I would be very happy if anybody can share some more details.

thanks a lot

Yours
Johannes

We will be adding some examples of this shortly.
In the meantime check out Stavros's Example

thx. Thats a fine example. But i've got an other problem.

everytime i try to call a function like

myreport = new Packages.com.evivax.bi.test.bi_report_1.getinstance();
myreport.initialize();

i got the following error:

A Birt exception occurred.
Plug-in Provider:Eclipse.org
Plug-in Name:BIRT Data Engine
Plug-in ID:org.eclipse.birt.data
Version:1.0.1
Fehlercode:data.engine.JSScriptInvalid
Fehlermeldung:Ungültiger Javascript-Ausdruck. Quelle:
DataSet:Datensatz.open, Zeile: 0, Ausdruck:
function_prefix_1126250336655();function
function_prefix_1126250336655(){myreport = new
Packages.com.evivax.bi.test.bi_report_1.getinstance();
myreport.initialize();}
Script-Engine-Fehler: TypeError: [JavaPackage
com.evivax.bi.test.bi_report_1.getinstance] is not a function.

i pushed my jar file into
eclipse\plugins\org.eclipse.birt.report.viewer_1.0.1\birt\WE B-INF\lib

but i doesn't feel like it's getting a touch on it. But i'm not sure if
its a missing jar error. With other functions the same error appear.

didn't you miss a pair of brackets after bi_report_1 in this line:
myreport = new
Packages.com.evivax.bi.test.bi_report_1.getinstance();?

I believe it might be better using:
myreport = new
Packages.com.evivax.bi.test.bi_report_1().getinstance();

But I'm not sure, since I didn't use Packages to instanciate an object
yet...

no that will normaly do.

My Problem lays in an other direction:
http://www.mozilla.org/rhino/ScriptingJava.html
says:

--
One thing to be careful of is Rhino’s handling of errors in specifying
Java package or class names. If java.MyClass is accessed, Rhino attempts
to load a class named java.MyClass. If that load fails, it assumes that
java.MyClass is a package name, and no error is reported:

js> java.MyClass

[JavaPackage java.MyClass]

Only if you attempt to use this object as a class will an error be reported.
--
So my jar file isn't loaded correctly and the error misleads me into
wrong direction.

Johannes,

Are you doing this on the Open method of the Datasource or Dataset?
I believe there is a bug on the Open of the Datasource.
Try it on the Dataset.
