cannot access jpcap.packet.EthernetPacket bad class file: C:\j2sdk1.4.2_09\jre\lib\ext\jpcap.jar(jpcap/packet/EthernetPacket.class)
class file has wrong version 49.0, should be 48.0
Please remove or make sure it appears in the correct subdirectory of the classpath.

The error message is the answer. The version 48.0 is expected, but you deliver the version 49.0.
