Deploying for a scripted function in "RCP BIRT Report Designer"

Hi, 
 
i just have a little problem: 
 
I did that tutorial for creating a scripted datasource / dataset. 
Here is the link: 
<a class='bbc_url' href='http://download.eclipse.org/birt/downloads/examples/scripting/scripteddatasource/scripteddatasource.html'>Created by Camtasia Studio 3</a> 
Within of eclipse it works fine. 
 
But if I would like to deploy it into "RCP Report Designer" I get an exception 
that the class SimpleClass isn´t defined. 
 
Following exception I get: 
<pre class='_prettyXprint _lang-auto _linenums:0'>
A BIRT exception occurred.
Plug-in Provider:Eclipse.org
Plug-in Name:BIRT Data Engine
Plug-in ID:org.eclipse.birt.data
Version:2.5.0.v20090605
Error Code:data.engine.BirtException
Error Message:A BIRT exception occurred: There are errors evaluating script "__bm_open()":
ReferenceError: "SimpleClass" is not defined. (<inline>#3). See next exception for more information.
There are errors evaluating script "__bm_open()":
ReferenceError: "SimpleClass" is not defined. (<inline>#3)
</pre>
 
The aim is to put the classes into a jar-file, later I would like to use more classes for scripting in the future. 
A jar-file is tidier 
 
I packed this classes into a jar-file and put it into that folder: 
BIRTbirt-rcp-report-designer-2_5_0pluginsorg.eclipse.birt.report.viewer_2.5.0.v20090520birtscriptlib 
 
After a restart of the "Birt Report Viewer" it doesn´t work. 
 
 
Here are the java-class and the scripts for you to copy in: 
 
java-class: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
package test;
import java.util.Vector;
public class SimpleClass
{
public Vector readData(){
//This function simulates a read from an EJB/DB
Vector rtnV = new Vector();
rtnV.add(new String[]{"ANG Resellers", "1952 Alpine Renault 1300","Red"});
rtnV.add(new String[]{"AV Stores, Co.", "1969 Harley Davidson Ultimate Chopper","Blue"});
rtnV.add(new String[]{"Alpha Cognac", "1969 Ford Falcon","Blue"});
rtnV.add(new String[]{"American Souvenirs Inc", "1968 Ford Mustang","Green"});
rtnV.add(new String[]{"Amica Models & Co.", "1969 Corvair Monza","Blue"});
rtnV.add(new String[]{"Anna's Decorations, Ltd", "1969 Corvair Monza","Yellow"});
rtnV.add(new String[]{"Anton Designs, Ltd.", "1970 Plymouth Hemi Cuda","Orange"});
rtnV.add(new String[]{"Asian Shopping Network, Co", "1969 Dodge Charger","Plum Crazy Purple"});
rtnV.add(new String[]{"Asian Treasures, Inc.", "1969 Corvair Monza","Red"});
rtnV.add(new String[]{"Atelier graphique", "1972 Alfa Romeo GTA","Metalic Silver"});

return (rtnV);
}

public static void main(String[] args)
{
SimpleClass sc = new SimpleClass();
Vector rtn = sc.readData();
for( int i=0; i<rtn.size(); i++ ){
String[] sa = (String[])rtn.get(i);
System.out.println(sa[0] + "--" + sa[1] + "--" + sa[2] );
}
}
}
</pre>
 
open: 
<pre class='_prettyXprint _lang-auto _linenums:0'>
importPackage( Packages.test );
favoritesClass = new SimpleClass();
favorites = favoritesClass.readData();
totalrows = favorites.size();
currentrow = 0;
</pre>
 
fetch: 
<pre class='_prettyXprint _lang-auto _linenums:0'>
if( currentrow >= totalrows ){
return(false);
}
var favrow = favorites.get(currentrow);

var Customer = favrow[0];
var Favorite = favrow[1];
var Color = favrow[2];

row["Customer"]=Customer;
row["Favorite"]=Favorite;
row["Color"]=Color;
currentrow = currentrow + 1;
return (true);
</pre>
 
close: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
favoritesClass = null;
favorites = null;
</pre>
 
 
Do you know where I have to put the jar-file for working of 
scripts within of "RCP Report Designer"? 
 
And what anything else I have to do for the correct working? 
 
Thank you very much.

On the website: 
<a class='bbc_url' href='http://www.eclipse.org/birt/phoenix/deploy/reportScripting.php#javaevents'>Report Scripting</a> 
 
I could find following: 
 
If you are testing the event handler in the designer either add the jar to the scriptlib folder of the viewer plugin (org.eclipse.birt.report.viewer_version located in the designer install/eclipse/plugins directory) or add the Java project that contains the event handler to the workspace which contains your BIRT report project. 
 
--> I have done that. 
 
So what is my mistake?

Hi, 
 
a short update to tell you something misterious: 
 
Firstly, on my computer there are installed following: 
- Eclipse with BIRT plugin 
- BIRT Report Designer 
 
I copied the content of that folder eclipsepluginsorg.eclipse.birt.report.viewer_2.5.0.v20090520 
 
into that place: 
birt-rcp-report-designer-2_5_0pluginsorg.eclipse.birt.report.viewer_2.5.0.v20090520 
 
In that folder is also the jar-file, which includes the package test and inside the Class "SimpleClass". 
 
Both folders org.eclipse.birt.report.viewer_2.5.0.v20090520 in eclipse and birt report viewer are therefore the same. 
 
 
In Eclipse I can run a new Eclipse-Instance. In this instance i open the report design view and create a scripted data source / data set (see my previous posts). 
After running of this report: ---->>> it works 
(I get the data of the Java-class SimpleClass with no exception) 
 
 
But in "rcp birt report viewer" with the same jar-files and properties-files, nearly everything is the same and --->>> it doesn´t work 
I get the BIRT exception withe the "SimpleClass" is not defined message. 
 
What can I do? Where is my mistake? 
 
Please experts would you help me? 
 
The whole day I tried to find a solution. 
 
Thanks

Now I tested it a lot of times and on different computers.

I copied the same "rcp report designer" with the same reports to the other computer.

It is very strange: It works on the one computer, but not on the other.

Does anybody know, why?

Is it maybe because of the java version?
How can I change the java version, which will started the designer?

Hopefully somebody knows that problem.
It's enough to drive one to despair.

Thx+Bye

I could solute it. The firm, where i work for, has updated
the java version of 1.5.x. But on my local pc I program
with java 1.6.
The default java version was therefore 1.5. and with this
version it doesn´t work.

Now I have to reinstall java 1.6 and the default one was the 1.6.

It was exhausting to indentify this problem, but now it works again.
