I want use jnetpcap in my project.While I use jnetpcap in eclipse,there is no error.However,when jnetpcap is used on S4,the error comes:java.lang.NoClassDefFoundError: Could not initialize class org.jnetpcap.packet.PcapPacket.I make sure that the jnetpcap.jar is in the .s4r file.There is class org.jnetpcap.packet.PcapPacket in the jnetpcap.jar.And I also load the native libraries of jnetpcap in my program.I don't know where is wrong.What's the difference between eclipse and s4 while running the program?

Are you building s4r with packaged dependencies, making it available somewhere (share file system or http), referring to it when you deploy the app and starting the nodes with "s4 node -c=<cluster name>" ?
