Hello,
I know this problem is well known and you can find many hints when
searching (google,...). But I can't find any solution.
The problem:
I wrote a small java application.
This program uses a dll file.
The dll file (it's the jacob.dll from
http://sourceforge.net/projects/jacob-project/) is in
"C:\WINDOWS\system32".
When I start the program manually (windows console) with
"java -classpath .;D:\Projekte\jar\jacob.jar JacopProbe"
everything work fine/perfect.
But the same code in a eclipse java project doesn't work.
As you can see (in the error message) my java.library.path property points
to "C:\WINDOWS\system32". Setting
-Djava.library.path="C:\WINDOWS\system32" as an vm argument in the run
configuration doesn't work too.
I'm using Eclipse SDK Version: 3.1.0 Build id: I20050610-1757.
Any suggestions?
Thanks in advanced,
Gerd Richter
