Do you mean that your application is working correctly without using the 
Wrapper,
but when using the Wrapper you are getting the error below?

 From this part of your output, I can see that the Wrapper will only 
load native libraries
from the C:\WINNT\System32 directory.  You must have the following in 
your config
file:

wrapper.java.library.path=C:/WINNT/System32

Are you installing the Wrapper.DLL file into the C:/WINNT/System32 
directory?
That will work, but it will mean that all applications on a given 
machine will have
to be using the same version of the Wrapper.   I usually keep the 
Wrapper.DLL
and Wrapper.exe files with the application being installed.  That also keeps
the Windows directory from getting cluttered.  (Just personal preference 
though)

This error usually means that the npjavanative3.DLL file can not be 
found on the
java.library.path.   I assume that this is a DLL that is specific to 
your application?
Please verify that it exists.

If you wish, starting with Wrapper version 2.2.9 (The one you are 
running) you can
specify multiple directories in the library search path.

wrapper.java.library.path.1=C:/WINNT/System32
wrapper.java.library.path.2=C:/Program Files/AppHome/lib

Can you go back and check the command you are using to launch your 
application
when not using the Wrapper.  Make sure that there are not any other 
directories
where libraries are being loaded.   Note that the current directory will 
only be
searched if it is included in the path:

wrapper.java.library.path.1=C:/WINNT/System32
wrapper.java.library.path.2=./

My only guess right now is that your npjavanative3.DLL file is not being 
found. :-/
