duplicate class error

I decompiled a jar file (using jad) and then created a new Java Project using JCreator (an IDE). Now when I am compiling the project it gives 4 different kinds of errors (70 total) :

1. "duplicate class" errors for some classes like:

C:\Program Files\Xinox Software\JCreatorV3LE\MyProjects\WhiteBoard\com\inMeeting\client\mde\MDEView.java:21: duplicate class: com.inMeeting.client.mde.MDEView.JTabbedPaneChangeListener
class JTabbedPaneChangeListener
^
C:\Program Files\Xinox Software\JCreatorV3LE\MyProjects\WhiteBoard\com\inMeeting\client\whiteboard\gui\ColorDlg.java:16: duplicate class: com.inMeeting.client.whiteboard.gui.ColorDlg.SymWindow
class SymWindow extends WindowAdapter

2. "cannot resolve symbol" errors like:

C:\Program Files\Xinox Software\JCreatorV3LE\MyProjects\WhiteBoard\com\inMeeting\client\white\ConvWhiteBoard.java:8: cannot resolve symbol
symbol : class WhiteEventHandlerImpl
location: package impl
import collab.interfaces.impl.WhiteEventHandlerImpl;

3. "package does not exist" errors like:

C:\Program Files\Xinox Software\JCreatorV3LE\MyProjects\WhiteBoard\com\inMeeting\client\white\ConvWhiteBoard.java:9: package collab.interfaces.rmi does not exist
import collab.interfaces.rmi.*;

4. "not an enclosing class" error like:

C:\Program Files\Xinox Software\JCreatorV3LE\MyProjects\WhiteBoard\com\inMeeting\client\whiteboard\gui\TextPropertyDlg$1.java:20: not an enclosing class: com.inMeeting.client.whiteboard.gui.TextPropertyDlg
TextPropertyDlg.access$updateFigureFont(TextPropertyDlg.this);

I have not coded this but have to get it working. Does anyone have some idea why these errors could be coming and how I should proceed to rectify them ? Any help or suggestions would be appreciated. Thanks.

Did you ensure that your directory structure matches the package
structure declared in the source files?

I am not sure what you mean here about matching directory structure but this
is what I did:

1. unzip whiteboard.jar which leads to a main directory com and some further
subdirectories.
2. Next I went to the top directory and ran jad which decompiled all .class
files into .java files into a folder src.
3. Then I created a new project in Jcreator and added the folder src to the
project.
4. Now when I compile the project I get the following errors:

1. "duplicate class" errors for some classes like:

C:\Program Files\Xinox
Software\JCreatorV3LE\MyProjects\WhiteBoard\com\inMeeting\client\mde\MDEView.java:21:
duplicate class: com.inMeeting.client.mde.MDEView.JTabbedPaneChangeListener
class JTabbedPaneChangeListener
^

2. "cannot resolve symbol" errors like:

C:\Program Files\Xinox
Software\JCreatorV3LE\MyProjects\WhiteBoard\com\inMeeting\client\white\ConvWhiteBoard.java:8:
cannot resolve symbol
symbol : class WhiteEventHandlerImpl
location: package impl
import collab.interfaces.impl.WhiteEventHandlerImpl;

3. "package does not exist" errors like:

C:\Program Files\Xinox
Software\JCreatorV3LE\MyProjects\WhiteBoard\com\inMeeting\client\white\ConvWhiteBoard.java:9:
package collab.interfaces.rmi does not exist
import collab.interfaces.rmi.*;

4. "not an enclosing class" error like:

C:\Program Files\Xinox
Software\JCreatorV3LE\MyProjects\WhiteBoard\com\inMeeting\client\whiteboard\gui\TextPropertyDlg$1.java:20:
not an enclosing class: com.inMeeting.client.whiteboard.gui.TextPropertyDlg
TextPropertyDlg.access$updateFigureFont(TextPropertyDlg.this);

Am I missing something very basic here ? I think the directory structure of
the source files is or shd be the same as that in the jar file ... Thanks.

This is just so that I know how detailed the answer needs to be: Are you
a Java programmer?

As you might have guessed I am not an experienced Java programmer... I was
however able to resolve the errors I mentioned in my previous post by
including a jar file from which packages were to be imported. It was a very
basic error I guess but since I am new to Java I couldnt make that out in
the beginning ! Thanks for your help and suggestions.
