Using 'getClasses' for reflection / introspection - not found in Jdev

Question

Hi people,
I am using Jdeveloper 10.1.3.0.4 and I am trying to use some of java's reflection / introspection features.
- I am trying to use the getClasses method, part of the 'Class' class.
However, Jdeveloper is telling me 'method not found.' The getClass method
is found OK, but not getClasses, which looks like a standard method in 'Class' in the java doc. Anyone know how to pull this one in ? I am coding import java.lang.Class; explicitly as well.
Specifically, my need is to determine, at runtime, a list of the lowest-level 'leaf node' subclasses in a specific class inheritance tree. I reckon I should be able to do this with a recursive routine that uses getClasses on each class; when this returns an empty array I know I am at a lowest-level subclass. However it's failing on the first hurdle -
static House myHouse = new House(); // House is the simple class I want to test
static Class[] array_of_classes ;
array_of_classes = myHouse.getClasses();
-> method getClasses not found in <current package.class>
on a similar vein, I tried adding
import java.lang.reflect;
- this gives java.lang.reflect not found.
My only alternative is to code my program in a totally non-OO way! :-(
please help!
thanks!!!

Hi,
I resolved the other errors by changing all references from com.bea.jcom.Variant
etc to com.linar.jintegra.class name..all were present under the com.linar.jintegra
package.
Thank you all anyways,

Hi,
We are generating java classes for the COM dll using JCOM com2java compiler.
We are getting a compilation error for import class not found when compiling
the
generated Proxy java source code. It can't find the com.bea.jcom.Dispatch
class that
the generated Proxy java source code extends. It also can't find com.bea.jcom.Variant
or com.bea.jcom.Param. These are interfaces or data types or classes used
by COM
library.
I added weblogic.jar to my class path and the only Dispatch class i found
inside
the weblogic.jar is com.linar.jintegra.Dispatch;
We have com objects for which we want to develop an EJB client to interface
with
the COM object using JCOM with Native Mode disabled.
Any help on the compilation error..I tried changing the extends for Dispatch
to com.linar.jintegra.Dispatch
but the other errors are still there.
To begin with, I think the generated code should not refer to any of the
COM data
types.
Any help please.
Thank you in advance,
Regards,
