Installation issue with Scilab-5.0.3

[Prakash Velayutham]

Hi,

I have tried to install Scilab 5.0.3 on my OpenSUSE 10.3 system (and  
also tried to compile from source), but when I try to invoke scilab  
binary after installation, I get

Warning: Could not find Java package '/usr/local/src/prakash/scilab/ 
new/newscilab/scilab//modules/helptools/jar/ 
org.scilab.modules.helptools.jar'.
Some problems during the loading of the Java libraries occured.
This could lead to inconsistent behaviours.
Please check SCI/etc/classpath.xml.
Could not create a Scilab main class. Error:
Exception in thread "main" java.lang.NullPointerException

Scilab cannot create Scilab Java Main-Class (we have not been able to  
find the main Scilab class. Check if the Scilab and thirdparty  
packages are available).

Any idea how this can be resolved?

Thanks,
Prakash
