Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: no jpcap in java.library.path

is the error I keep getting, do I need to add a path to jcap? or change my configurations?

Solution

  • UnsatisfiedLinkError means that Java cannot find a native library. If you're on Windows, it's looking for jpcap.dll; if it's Linux or OS X, it's probably jpcap.so. You need to set the system property java.library.path to include the directory that contains the library.

    For example, if you have jpcap.dll in a directory named C:\MyProject:

    java -Djava.library.path=C:\MyProject com.mypackage.MyProgram
