native method problems

Hi,

For some reason Jigsaw loads a native library libhdf.so, but when I invoke
the native method, it gives me an UnsatisfiedLinkError. This implies that 
the "Java Virtual Machine cannot find an appropriate native-language
definition of a method declared native". 

I don't get this error when I run JSDK2.0/bin/servletrunner.

Any ideas? I'm using tcsh and am assuming the LD_LIBRARY_PATH is getting
exported correctly, as it does with servletrunner.

Thanks,
Apu.
