[Wrapper-user] Unable to load wrapper.dll

[<Ale...@Qu...>]

Hello, Wrapper users,

[Duplicate because I sent the first copy from the wrong address - 
moderator please discard first copy]

I am having trouble running my application under the Wrapper because
it is unable to load the wrapper.dll. As you can see from the console
log below, the Wrapper code can "see" the dll, but the system gives an
UnsatisfiedLinkError. As you can see at the foot of the log, a dir
command using the path cut-and-pasted from the error message says that
the DLL is there. I have reloaded the wrapper.dll from the unzipped
issue kit a couple of times, and viewed it with the Microsoft
Dependency Walker to see if it is corrupted, and it does not appear to
be.

I have run the WrapperTest from the distribution directory and it
works fine. My application still will not run even when I set its
library search to point to the copy of the dll being used by
TestWtqapper i.e.
wrapper.java.library.path.1=C:\Wrapper\wrapper_win32_3.1.2\lib

I know this problem has come up before on the list, but I did not see
any resolution posted.

Thanks in advance for any assistance.

Alec Cawley
