Loading dlls in tomcat windows service
There are cases when your web archive loads dll files to use native functions. Generally if you put the dlls on the system path it gets picked up by tomcat however you may need system restart to get it working. If tomcat is installed as a windows service and you don't want to or cannot update the system path. Copy the dlls into the tomcat bin folder where the service was installed from and that should make all java.lang.UnsatisfiedLinkError exceptions go away.
