did u find a solution for this , I'm facing the same problem with websphere application server??!!!

I found the cause of the problem, The problem is because the application server contains a older version of
Rhino's js.jar, while BIRT uses the latest version (1.6RC1). Because the js.jar
in the application server is loaded before the one in BIRT, the older version
of class org.mozilla.javascript.Context is loaded. Since the older version of
class org.mozilla.javascript.Context doesn't contain function
initStandardObjects, a runtime java.lang.NoSuchMethodError happened.

its a bug on eclipse Bugzilla Bug site with no 105853
this is the link to this bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=105853

I test the solution with websphere application server V5.1 and it works.
