The AttachProvider implementation is used to attach to the target process. The AttachProvider implementation is obtained by invoking the static getPlatformProvider() method of the AttachProvider class. The following code fragment shows how to get an AttachProvider implementation:24AttachProvider provider = AttachProvider.getPlatformProvider();25String pid = "1234";26VirtualMachine vm = provider.attachVirtualMachine(pid);27The attachVirtualMachine(String) method of the AttachProvider implementation is used to attach to a target process. The argument to the attachVirtualMachine(String) method is the process identifier (PID) of the target process. The attachVirtualMachine(String) method returns a reference to a VirtualMachine implementation. This reference is used to load the agent into the target process. The following code fragment shows how to load the agent into the target process:28String agent = "agent.jar";29vm.loadAgentLibrary(agent, "");30The loadAgentLibrary(String, String) method of the VirtualMachine implementation is used to
