ServletResponse methods - Servlet 3.0

In this tutorial you will learn about the method of ServletResponse.

ServletResponse interface method generally provides setter and getter methods to set and get the appropriate value.

Here I am giving commonly used methods of ServletResponse interface. These are as follows :

  • setContentType() : This method is used to set the content type in which you want to response request made by client.
  • getContentType() : This method is used when you want to check the content type is using to response.
  • getWriter() : This method gives an object of PrintWriter class through which the text is send to the client.
  • getLocale() : This method is used to get the Locale for the response.
  • setLocale() : This method is used for set the Locale of java.util.Locale for the response.

Example :

Here I am giving a simple example that will demonstrate you about some of these methods.

package roseindia.urlExample;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet("/ServletResponseMethod")
public class ServletResponseMethod extends HttpServlet {
private static final long serialVersionUID = 1L;

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out= response.getWriter();
response.setContentType("text/html");
String cnt= response.getContentType();
out.println("Content Type = "+cnt);
int bs= response.getBufferSize();
out.println("<br>BufferSize= "+bs);
String chen= response.getCharacterEncoding();
out.println("<br>Charset = "+chen);
boolean bol= response.isCommitted();
out.println("<br>Is committed = "+bol);
}

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doGet(request, response);
}

}

Output :

When you will execute the above example you will get the output as :
