Unhappy UnsatisfiedLinkError on JNI access to Shared Library


Trying to do a simple JNI based "Hello World" demo of a Java class calling a c++ shared library on Linux (Knoppix/Debian) and keep getting

Exception in thread "main" java.lang.UnsatisfiedLinkError: no libName in java.library.path etc. etc..

I've tried all of the obvious things like:

export LD_LIBRARY_PATH=/home/user/librarypath

puting libName.so in /usr/local/lib and usr/lib

putting the java class and libName.so in the same directory.

Java 1.4.1, Knoppix 3.2

Any thoughts appreciated.

MikeC....

Problem solved (thanks to http://www.mindspring.com/~david.dagon/jni/Native.txt)

Java/Linux prepends lib and appends .so to the LoadLibrary call. Use LoadLibrary("Hello"); to load libHello.so.
