Adding dll to spring mvc project

Question

I have a spring mvc project using Eclipse Kepler and want to use a .net dll in that project.

I went through the process of getting the dll ready for java following this info

In my

spring project -> Properties -> Java Class Path -> libraries -> External Jar -> Located my jar used to call the c# methods.

Next added the native libs

spring project -> Properties -> Java Class Path -> libraries -> Located external jar added -> expand -> highlight Native Library Locaton -> path to where my dll's are located

In my spring mvc project code I can create an instance of the object in my external jar file.

MyJavaCallingComObject testObj = new MyJavaCallingComObject ();
testObj.GetDetails("John Doe");

GetDetails = supposed to return user information given the user name

However when i go to call a method I run into this

#
