Hi,
I am writing a servlet using oracle berkely db. I get the following
runtime error shown below. I think it is related to JNI but am unable
to resolve it. Has anyone fixed such a kind of problem before?

exception

The JNI binding cannot find the native library. You must install it
somewhere the JVM can find it.
