I am writing jsp-servlet application and getting 405 http-status. I was looking for a long time but I cannot understand what I do wrong.
My application server is Apache Tomcat-7.0.25.
My JSP forward page
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<body>
<jsp:forward page="/myservlet" />
</body>
</html>
My servlet
public class MyServlet extends HttpServlet {
private static final String url = "http://ibm.com";
public void doGet(ServletRequest request, ServletResponse response)
throws ServletException, IOException {
URLConnection conn = null;
URL connectURL = null;
try {
PrintWriter out = response.getWriter();
connectURL = new URL(url);
conn = connectURL.openConnection();
DataInputStream theHTML = new DataInputStream(conn.getInputStream());
String thisLine;
while ((thisLine = theHTML.readLine()) != null) {
out.println(thisLine);
}
out.flush();
out.close();
} catch (Exception e) {
System.out.println("Exception in MyServlet: " + e.getMessage());
e.printStackTrace();
}
}
}
My deployment descriptor (web.xml) file
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

What can be cause of this and how can I solve this problem? Do you have any supposes?
You have wrong types of parameters in the method toGet(). They should be HttpServletRequest and HttpServletResponse:
@Override
public void doGet(HttpServletRequest request, HttpServletResponse response)
Such bugs are very unpleasant, because they aren't easy to detect.
So don't disregard annotation @Override.
Use it to avoid different misprint and other unfortunate misunderstandings in method name or its signature. It'll help you to find these mistakes at compile time.
