Hello,
I am new to eclipse, I just installed the latest eclipseSDK_3.1M6 & tptp
builds. and wrote my first SWT app by just copying main() from the eclipse
tutorial which is somewhat outdated. Somehow the dll file is not in the
plugins\, but somewhere in the configurations\, so I copied it to the
following location.
-Djava.library.path=C:\eclipse_org_SDK3.1M6\eclipse\plugins\ org.eclipse.swt.win32_3.1.0\os\win32\x86
Still, it still can not find swt-win32-3128.dll. Can somebody help me with
this?
Thanks!

I saw people had similar problem, and I also unjar the following jar file
from the plugins\. But I still got the same error, I can see the 3128.dll
file is in the java.library.path, but it just can not be found from the
simple swt program, what's wrong, any ideas??
C:\eclipse_org_SDK3.1M6\eclipse\plugins\org.eclipse.swt.win3 2_3.1.0.jar
The above jar also included in the CLASSPATH.
