SF. jadclipse_3.3.0.jar to the % eclipse_home % \ plugins directory. Copy the Link Method to the following: Create D: \ myplugins \ net. SF. jadclipse_3.3.0 \ eclipse \ plugins directory structure, put jadclipse_3.2.4.jar under the Plugins directory (Note: D: \ myplugins is a directory dedicated to plug-ins for you ). Create a net.
