Jpcap isn’t a pure Java solution; it depends on the use of native libraries. Delivered Daily Subscribe Best of the Week Our editors highlight the TechRepublic articles, galleries, and videos that you absolutely cannot miss to stay current on the latest IT news, innovations, and tips.
How Jpcap works Jpcap tuhorial an event model to allow you to process packets. Capturing packets in Java isn’t a pure Java endeavor but, since it’s possible, it’s nice to know pjcap functionality exists. After choosing a device, you open it for listening by using the method Jpcap.
In order to capture packets, you need to tell Jpcap which network device you want to listen with. If you want to capture network packets in your Java program, you’ll need a little help because jocap parts of the core Java API give access to low-level network data. To get started, you must first create a class that implements the interface jpcap.

Both of the methods take two arguments: The output of executing the test jpcwp looks like this it’s shortened for space purposes: Once you have a list of device names, you must choose one for listening: The method returns an array of strings, and you use it jpdap this: The openDevice method returns a reference to a Jpcap object that will be used for capturing.

Capture network packets in Java with Jpcap
Inside the Raspberry Pi: The openDevice method requires four arguments: If you call processPacketthen Jpcap will capture packets until either the timeout specified in openDevice is exceeded or the maximum number of packets specified has been reached.
The maximum number of packets to capture can be -1 to indicate no limit and an instance of a class that implements JpcapHandler. Automatically sign up today! To execute the class, you must make sure that the virtual machine can find the Jpcap native library.
Now that you have the Jpcap instance, you can start listening by calling either processPacket or loopPacket.
