What is this?
This code is intended to solve a small, but annoying problem that occurs when loading native libraries (specifically DLLs) within a web container (Tomcat in this case).

It is important to only call this method once, as calling it multiple times will result in the following error:

To correct for this issue, you can load the DLL in a static initializer block, which guarantees that it is only loaded once for the lifetime of the classloader assigned to that web container.
static { System.loadLibrary("name-of-dll");}
However, if the webapp is redeployed within a runni
