[Scilab-Dev] [javasci] running scilab from a eclipse rcp application

[G. Azema]

He meant he cant get it to work when used in an eclipse based application, not
in eclipse. (an eclipse plug-in , or RCP application whichever you want 
to call it).

I have exactly the same problem, it works fine when used in a regular java
project, but doesnt work when used in an eclipse RCP application.

Did anyone find the solution for this ?

Thank you.

PS :
Here is the post I made on Scilab bugzilla :






Hello,

I am trying to use Scilab in my Java Application using javasci.

I am running under Windows 2000, and using Eclipse 3.6.

I have followed the steps indicated in the help which were
set the SCI environnement variable to scilab root
set the PATH environnement variable to SCI/bin

Create a java project from scratch.
Properties of project  --> Java Build Path -->  
librairies --> Add external jars
: javasci.jar.
Add a simple BasicExample.java file to my project

// A simple Java example 
// Filename: BasicExample.java

import javasci.Scilab;

public class BasicExample {
        public static void main(String []args){
        Scilab.Exec("disp((%pi^2)/6);");
        }
}

Run this and this works.
----------------------------------------------------

Now I am trying to do the same, in an eclipse plugin 
for my eclipse RCP application.
Compilation works fine but when I run the application I get a popup window
saying Scilab cant reach main java scilab
class. Please check thirdparty .... etc.
And in Eclipse console :
Ne peut pas accéder à la Classe Principale de Scilab:
java.lang.NoClassDefFoundError: org/scilab/modules/jvm/Scilab
        at javasci.Scilab.Initialize(Native Method)
        at javasci.Scilab.<clinit>(Unknown Source)
.........
Caused by: java.lang.ClassNotFoundException: 
org.scilab.modules.jvm.Scilab
        at
org.eclipse.osgi.internal.loader.BundleLoader.
findClassInternal(BundleLoader.java:506)

It seems that It cant find org.scilab.modules.jvm.Scilab.

So I also added the org.scilab.modules.jvm.jar to 
my classpath and run my application again and now I get this :
