I wrote this very simple servlet to take one argument from the URL ( page ) and
display the corresponding page. However, I am having trouble with the flow
control logic. page== "init" always evaluates to false. Can someone explain to
me what I am doing incorrectly.
Setup is Windows NT Workstation (SP3), Apache, Apache JServ, JDK1.3, JSDK2.0
The source follows:
import javax.servlet.http.*;
import javax.servlet.*;
import java.io.*;
public class SimpleApp extends HttpServlet {
public void displayPage ( PrintWriter out , String filename ) {
String page;
try {
RandomAccessFile inFile = new RandomAccessFile(
"D\\web\\htdocs\\simpleApp\\" + filename,"r");
while( (page = inFile.readLine()) != null ) {
out.print(page);
}
inFile.close();
}
catch(FileNotFoundException exception) {
out.println("File " + filename + " not found!");
}
catch(IOException exception) {
out.println("Error opening file " + filename + " for reading!");
}
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// get an PrintWriter from the response object
PrintWriter out = response.getWriter();
// prepare the response's content type
response.setContentType("text/html");
// get the page to display
String page = request.getParameter("page");
// print to the output stream!
if( (page == "init" ) || (page == "Start Over" ) ) {
displayPage( out , "index.html" );
}
if( page == "Confirm" ) {
displayPage( out, "confirm.html") ;
}
if( page == "Done" ) {
displayPage( out, "done.html" );
}
}
}
