I am writing a servlet to dynamicallt create an HTML file that holds an applet. I keep
running into weird class loader, bad magic number etc. errors.
Here is the code: by itself it works fine if I print it out as text/ascii but
currently I have the content type set to text/html:
----------------------------------------------------------------
import java.sql.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.StringTokenizer;
public class pageGenerator extends HttpServlet
implements SingleThreadModel {
Connection conn = null;
public void init( ServletConfig config ) throws ServletException {
super.init(config);
}
public void doGet( HttpServletRequest req,
HttpServletResponse res )
throws ServletException, IOException {
// Setup the stream
PrintWriter out = res.getWriter();
res.setContentType("text/html");
// Get parameters
String title_string = new String(req.getParameter("TITLE"));
String setup_string = new String(req.getParameter("SETUP"));
String multiple_string = new String(req.getParameter("MULTIPLE"));
String repname_string = new String(req.getParameter("REPNAME"));
out.println("<HTML>");
out.println( "<TITLE>"+title_string+"</TITLE>");
out.println( "<BODY>");
out.println( "<CENTER>");
out.println( "<TABLE BORDER CELLSPACING=5 CELLPADDING=5 COLS=1
WIDTH=\"45%\" BGCOLOR=\"#FFFFFF\">");
out.println( "<TR ALIGN=CENTER BGCOLOR=\"#000099\">");
out.println( "<TD>");
out.println( "<B><FONT FACE=\"Lucida Sans\">");
out.println( "<FONT COLOR=\"#FFFF99\">");
out.println( title_string);
out.println( "</FONT></FONT></B>");
out.println( "</TD>");
out.println( "</TR>");
out.println( "<TR ALIGN=CENTER VALIGN=CENTER>");
out.println( "<TD>");
out.println( "<APPLET CODE=\"reportUI\"");
out.println( "codebase=\".\"");
out.println( "width=430");
out.println( "height=410>");
out.println( "<PARAM NAME=\"SETUP\" VALUE=\""+setup_string+"\">");
out.println( "<PARAM NAME=\"MULTIPLE\"
VALUE=\""+multiple_string+"\">");
out.println( "<PARAM NAME=\"REPNAME\"
VALUE=\""+repname_string+"\">");
out.println( "</APPLET>");
out.println( "</TD>");
out.println( "</TR>");
out.println( "</TABLE>");
out.println( "</CENTER>");
out.println( "</BODY>");
out.println("</HTML>");
out.close();
}
}
Here is the error I get:
