sure that the init () method is complete.(2) Service () methodThe Ervice () method is the core of the Servlet. Whenever a client requests a HttpServlet object, the service () method of the object is invoked and passed to the method a request (ServletRequest) object and a response (Servletresponse) object as an argument. The service () method already exists in HttpServlet. The default service function is to invoke the DO function corresponding to the

Cobbler is an open source project that is used to deploy and install systems. Cobbler is not just a PXE server, he can also manage DNS and DHCP. In a general data center or production environment, DHCP is not allowed, but PXE requires DHCP, so we assign IP here based on the MAC address so that DHCP does not affect the existing network. 1.

into the servlet for the first time on the boot server or client. Regardless of how many clients access the Servlet, init () is not repeated. The default init () method is usually compliant, but it can also be overridden with a custom init () method, typically managing server-side resources. For example, you might write a custom init () to only mount a GIF image at a time, and improve the performance of the Servlet returning a GIF image and a request that contains multiple clients.
