The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Using Java to call 3rd party DLL, JNI?

Asked by jerra in Java Native Interface (JNI)

Tags: Java DLL JNI wrapper

I haven't had the time yet to investigate this further, I have very little time right now so I hope to get some pointers in which direction I should put my precious time as it is now. I need to access this VELLEMAN usb card from Java and the options I have from what I understand is to either wrap the VELLEMAN DLL using JNI or use 3rd party JAVA-USB bridge software and from there try to communicate with the card.

My question is basically, can I with JNI access any DLL without having access to the source code from which the DLL was compiled? I have the APIs from their documentation but thats all. The API seems quite simple and straightforward.

I very much hope for some advice which directions I should take, hope to get starting tomorrow morning.
