IŽm trying to instance a java object in the data set open method, but the
BIRT canŽt access my class.
I put my jar file in the path that are in help.
<ECLIPSE_INSTALL>\plugins\org.eclipse.birt.report.viewer\birt\WEB-INF\lib.
but is still not working.
I try all this commands in the data set open method:
1. var dados = new Packages.br.com.teste.Dados();
2. var dados = new br.com.teste.Dados();
3. importPackage(Packages.br.com.teste);

iŽm guess that Birt canŽt see my classes.
Anyone can help me?

Did you restart Eclipse after copying the file?

Yes, but the error donŽt stop.
I have a jar file dados.jar and inside him 2 files dados.class and
clientes.class, that belong to the package com.teste,
When i instance the class, like this:
var dados = new Packages.com.teste.Dados();
i get this error:

A Birt exception occurred.
Plug-in Provider:Eclipse.org
Plug-in Name:BIRT Data Engine

var i = dados.getIterator();}
Script engine error: TypeError: [JavaPackage com.teste.Dados] is not a

Do you have any ideia?
Thsnks,

I don't see anything wrong. Sounds and looks right.

Do you see package paths in the jar? In other words, if you open the
jar as a zip do you see com/teste in the path column?

Does your class access any other Jars that may not be in the classpath?
Drop the var if you use this class in the fetch method.

Yes, the class in jar file has the path com/teste. My class donŽt have
imports.
Can anyone send me a example that work?
The commands that i should put in script and the jar file if possible.
Send me to this e-mail: mateaju@ig.com.br
Instancing a java class in birt is extreme important to me.
Thanks,
Mateus

Add the Packages keyword in your script. See example below:

function beforeDrawSeries(series, renderer){
var m = series.getMarker();
var markerMod = new
Packages.org.eclipse.birt.report.viewer.utilities.MarkerModi fier();
var m2 = markerMod.modifyMarker(m,5);
}
