Thanks for your reply. But that was not the reason of my problem. I
tried to write a servlet beeing as simple as possible:
package de.medigration.telechiv.UI_Servlets;
/*
* Imports
*/
import java.io.*;
import java.util.Date;
import javax.servlet.*;
import javax.servlet.http.*;
public class MessageServlet extends HttpServlet
implements SingleThreadModel {
private
ServletConfig config;
public void init (ServletConfig config)
throws ServletException {
this.config = config;
}
public void destroy() {} // do nothing
public ServletConfig getServletConfig() {
return config;
}
public String getServletInfo() {
return "User Interface Servlet";
}
public void doPost (HttpServletRequest req, HttpServletResponse
res)
throws ServletException, IOException {
/* Create Output Writer */
res.setContentType( "text/html" );
ByteArrayOutputStream outBuffer = new ByteArrayOutputStream
(255);
PrintWriter out = new PrintWriter(outBuffer, true);
/* Write Head of HTML-Page */
out.println( "<html>" );
out.println( "<head>" );
out.println( "<title> Message </title>" );
out.println( "</head>" );
out.println( "<body>" );
out.println( "Hello World!" );
out.println( "</body>" );
out.println( "</html>" );
res.setContentLength(outBuffer.size());
outBuffer.writeTo(res.getOutputStream());
out.close();
}
}
