public void init(javax.servlet.ServletConfig cfg)
throws javax.servlet.ServletException
The servlet container calls the init
method exactly once after instantiating the servlet.
The init method must complete successfully
before the servlet can receive any requests.
The servlet container cannot place the servlet into service
if the init method
ServletException

configuration and initialization parametersjavax.servlet.ServletException - if an exception has occurred that

ServletConfig object, which contains
initialization and startup parameters for this servlet.
The ServletConfig object returned is the one
passed to the init method.
Implementations of this interface are responsible for storing the
ServletConfig object so that this
method can return it.

IOException
This method is only called after the servlet's init()
method has completed successfully.
Servlets typically run inside multithreaded servlet containers that can handle multiple requests concurrently. Developers must be aware to synchronize access to any shared resources such as files, network connections, and as well as the servlet's class and instance variables. More information on multithreaded programming in Java is available in the Java tutorial on multi-threaded programming.

The string that this method returns should be plain text and not markup of any kind (such as HTML, XML, etc.).

service method have exited or after a timeout
period has passed. After the servlet container calls this
method, it will not call the service method again
on this servlet.
This method gives the servlet an opportunity to clean up any resources that are being held (for example, memory, file handles, threads) and make sure that any persistent state is synchronized with the servlet's current state in memory.
