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