while coding in eclipse. I am using bluecove 2.1.0 and a 64-bit version of Windows 8.
Can anyone please suggest me a fix?
these two links helped me a lot
this is compatible 64bits
http://snapshot.bluecove.org/distribution/download/2.1.1-SNAPSHOT/2.1.1-SNAPSHOT.62/
documentation
There is even a newer version: http://snapshot.bluecove.org/distribution/download/2.1.1-SNAPSHOT/2.1.1-SNAPSHOT.63/
Also, it's important to note that this replaces any other bluecove jar. Because the message indicated missing libraries, I initially added this, and it caused a version conflict.
Actually the JAR you have added does not contains x64 dll. Download the JAR from the below link and use it. It worked for me. http://www.java2s.com/Code/Jar/b/Downloadbluecove211jar.htm
