How to fix AccessControlException with JNI and a DLL?

Question

We made a DLL called Sample1.dll using Visual C++. Our Java code seems able to load it OK.
The following does not throw an error:
System.loadLibrary("Sample1");
When we try to call a method in the DLL, we get an UnsatisfiedLinkError exception.
We thought we may have spelled the method name wrong, but it seems to be right. We even found a utility that lets you look inside of DLL's.
We added some code to try to explore this:
SecurityManager sm = new SecurityManager();
try {
sm.checkLink("Sample1");
catch (AccessControlException e) {...
The above code always throws an AccessControlException.
What does this mean? Is our problem one of security?

Answer 1

First off, I don't know the answer to your question, but I may be able to help you help others to answer it. Have you considered posting your code here for us to see and to play with. We don't want to see all of your code, but rather you should condense your code into the smallest bit that still compiles, has no extra code that's not relevant to your problem, but still demonstrates your problem, in other words, an SSCCE (Short, Self Contained, Correct (Compilable), Example). For more info on SSCCEs please look here:

Also, when posting your code, please use code tags so that your code will be well-formatted and readable. To do this, place the tag [code] at the top of your block of code and the tag [/code] at the bottom, like so:
[code]
  // your code block goes here.
