Error "java.lang.NoClassDefFoundError: sun/security/provider/Sun" in 10.1.2

Question

Hi,
I developed an ADF UIX application in JDeveloper 10.1.2. It works fine when I run on embedded oc4j in my machine.
I deployed it to Oracle Application Server 10g in AIX. When I run the application from the Application Server and try to open a uix page with data I get the following error:
500 Internal Server Error

Can anybody tell/help why I am getting this error?
Thanks

I believe this counts to be a bug in adf. I met with such errors as well in migration 1012 from NT to AIX platform, and after decompiling adf jar code and tak a look at it, the following code block indicates that In class- oracle.jbo.client.Configuration
, it is hard coded to get secure provider- sun/security/provider/Sun, as listed below...
import sun.security.provider.Sun;
static void checkSecurityProviders()
Provider aprovider[] = Security.getProviders();
boolean flag = false;
for(int i = 0; i < aprovider.length; i++)
if(!aprovider.getName().equals("SUN"))
continue;
flag = true;
break;
if(!flag)
try
Sun sun = new Sun();
Security.addProvider(sun);
catch(Exception exception)
exception.printStackTrace();
