java.library.path and "can't find dependent library"

Hello,

I have begun looking into the webclient API. It seems quite nice for my
needs. However, I have begun stumbling over some issues with Netbeans
and using the webclient.  In this case, I'm printing out the value of
java.library.path to the console when I perform my tests.

In a nutshell, these are the facts:

- Test browser runs fine from console (by running ant against
build.xml)
- Without setting java.library.path, I run the app. It complains of "No
webclient found". The value for java.library.path is what is on the
system PATH variable.
- I stripped the trailing ";;" from my system path prior to running (I
read somewhere that trailing empty values may confuse the JVM)
- Running my simple client from the IDE with JVM parameters:

  -Djava.library.path='C:\Program Files\mozilla 1.7'

  The resulting error was "Can't find dependent library".  Printing the
java.library.path yields soley: C:\Program Files\mozilla 1.7
- With a file monitor enabled, I can see it successfully finding
webclient.dll. The problem is when the java.exe process is searching
for xpcom.dll.  Ironcially, it is in the same folder as webclient.dll.

So, I am at a loss.  There do seem to be a couple of vars set in
build.xml, but I'd like to see if anyone else has some ideas.

Best regards,
-Sean
