Hi,
I'm migrated a proof of concept project from JSF to GWT, so far it
rocks.
Part of the deal is a native library (written in C, linked to Java
using JNI).
The resulting DLL is placed in C:\Program Files\Java\jdk1.6.0_11\jre
\bin
In the JSF project this worked fine.
In GWT it doesn't. I tried moving the DLL to c:\windows but that
didn't help.
I get the following error when perfoming a RPC call that invokes the
DLL (in the Hosted Mode Jetty output). See below
Any help would be greatly appreciated
