How to resolve UnresolvedExternal exceptions while deploying jni apps in Tomcat

Cause:

UnresolvedExternal errors are caused in JNI applications when the class files tries to reference a native method in a shared object or dll and is unable to find the dll.

Solution:

• Find out Tomcat's current java.library.path
• Copy your application dlls to this path
• The jars would remain within the application's war file
• The dlls need not be along with the application jars
