# netsnmpj.dll: The specified procedure could not be found

Hi guys,
I am developing with netsnmpj. I have downloaded the netsnmpj tookit from http://sourceforge.net/projects/netsnmpj/files/.
When I use the example of the netsnmpj in Eclipse, it can be compiled successfully. But when I run it, the following errors appeared.
I have added the netsnmpj.dll to the jdk location, but why it shows "The specified procedure could not be found"?
I have spent one day on this issue.
Need your help and many thanks.

java.lang.UnsatisfiedLinkError: C:\Program Files\Java\jdk1.6.0_17\jre\lib\System\netsnmpj.dll: The specified procedure could not be found
