steps to test call scilab

BUG DESCRIPTION:
----------------

Firstly，I  try to prove I can call scilab in a Java Project,it is succeed. I test java1 project(Java project), run as>Java Application, it's ok to
call scilab and I can get the result in console.
PS. To call scilab, I have set some system variables in my laptop.
Classpath=.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;C:\Program
Files\scilab-6.0.1\modules\javasci\jar\org.scilab.modules.javasci.jar;C:\Program Files\scilab-6.0.1\modules\types\jar\org.scilab.modules.types.jar
Path=C:\ProgramData\Oracle\Java\javapath;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0;%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;C:\Program
Files\scilab-6.0.1\bin
SCI=C:\Program Files\scilab-6.0.1


Secondly,I try to call scilab in eclipse application, but it didn’t succeed.
1.    I create a plugin project plugin1, choose "Hello world command" template.
2.    plugin1> right click>new folder lib, add three jars about calling scilab.
3.    In MANIFEST.MF>Runtime, Classpath, I add the jar from lib.
4.    add call scilab code in SampleHandler.java like the picture
5.    launch the second eclipse application
6.    click the sample menu, the hello is shown , but the result should be called from scilab is not shown in console.

I think it is due to the path C:\Program Files\scilab-6.0.1\bin I didn't set in plugin project, so it can not find related jars.
where should I set ? In Environment when launch? or the error is caused by other reasons.



ERROR LOG:
----------
It tells me that if Scilab is used form java, make sure that your IDE(ex:Netbeans, etc)is not adding extra dependencies which could not be found at
runtime.
