Using Java-Like Output Functions

HydraExpress Components : Servlet Development Guide : PART III Programming : Creating Responses : Creating an HTTP Response : Using Java-Like Output Functions

Each response object contains an output object that supports a set of overloaded print() and println() functions described in the Servlet Specification. These functions are convenient for programmers accustomed to Java servlet programming. The sample below shows a doGet function that creates a simple HTML response with the Java-like functions:

void myServlet::doGet (rwsf::HttpServletRequest& request,

rwsf::HttpServletResponse& response)

{

response.setContentType("text/html"); // 1

rwsf::ServletOutputStream& out = response.getOutputStream(); // 2

out.println("<html>"); // 3

out.println("<head><title>Simple Response</title></head>");

out.println("<body bgcolor=\"white\">");

out.println("<h1>Simple Response</h1>");

out.println("A simple HTML response.");

out.println("</body></html>");

}

//1 Sets the Content-Type of the response to text/html. A client may use the Content-Type to determine the kind of document in the response. Without this line, some clients interpret the response as plain text.

//2 Gets the output stream from the response.

//3 Prints a line of the response to the client. In this version, the servlet prints the string to the client using the Java-like function println().
