INTERVIEW QUESTIONS J2EE SERVLET DETAILS

Question: If you want a servlet to take the same action for both GET and POST request, what should you do?

Answer: Simply have doGet call doPost, or vice versa.

Simply have doGet call doPost, or vice versa. Source: CoolInterview.com

u can call doGet Method in doPost method and vice versa i.e

public void doGet(HttpServletRequest req,HttpServletResponse resp) throws ServetException,IOException
{
doPost(req,resp);
}
public void doPost(HttpServletRequest req,HttpServletResponse resp) throws ServetException,IOException
{
doGet(req,resp);
}

-----------------------------
we can create a method say x and call that method in both i.e
doGet
{
x();
}
doPost()
{
x();
} Source: CoolInterview.com

The first answer above will create a deadlock, so to take the same action for both Get and Post requests, call one of the doGet() or doPost() methods from the other method, not both.
public void doGet(HttpServletRequest req,HttpServletResponse resp) throws ServetException,IOException
{
doPost(req,resp);
}
public void doPost(HttpServletRequest req,HttpServletResponse resp) throws ServetException,IOException
{
Action to be taken
} Source: CoolInterview.com

You can have doGet() and doPost() method and another method say handleRequest() called by both of them. and handleRequest can do the rest of the operations. Source: CoolInterview.com

override service method of Servlet interface or Generic Servlet class Source: CoolInterview.com
