The dllName property contains the name of a C language DLL to be associated with an EGL NativeLibrary part. You cannot override this name at run time. If you do not specify a value here, you must specify the name of the DLL in the vgj.defaultI4GLNativeLibrary Java™ runtime property. The DLL must reside in the directory path identified in a runtime variable; that variable is either PATH (on Windows® 2000/NT/XP) or LIBPATH (on UNIX® platforms).
