I have the following code which will call the server through HttpUrlConnection.
1)
String response = HttpUtil.submitRequest(json.toJSONString(), "http://ipaddr:port/SessionMgr/validateSession?sessionId=_78998348uthjae3a&showLoginPage=true");
The above lines will call the following code:
2)
public static String submitRequest(String request, String **requestUrl**) {
try {
URL url = new URL(requestUrl);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
OutputStream os = conn.getOutputStream();
os.write(request.getBytes());
os.flush();
if (conn.getResponseCode() != HttpURLConnection.HTTP_OK) {
throw new RuntimeException("Failed : HTTP error code : "
+ conn.getResponseCode());
}
BufferedReader br = new BufferedReader(new InputStreamReader(
(conn.getInputStream())));
String output;
StringBuffer sb = new StringBuffer();
while ((output = br.readLine()) != null) {
sb.append(output);
}
conn.disconnect();
return sb.toString();
} catch (MalformedURLException e) {
} catch (IOException e) {
}
return "";
}
The "requestUrl" will go to the
servlet below:
3)
public class ValidateSessionServlet extends HttpServlet {
String session = req.getParameter(sessionId);
if (session == null) {
// redirect to servlet which will display login page.
response.setContentType("text/html");
String actionUrl = getIpPortUrl(request)
+ PropertyConfig.getInstance().getFromIdPConfig(globalStrings.getCheckSSOSession());
out.write("<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\" \"http://www.w3.org/TR/html4/loose.dtd\"> \n");
out.write("<html><head><body onload=\"document.forms[0].submit()\">\n");
out.write("<form method=\"POST\" action=\"" + actionUrl + "\">\n");
out.write("<input type=\"hidden\" name=\"locale\" value=\"" + locale + "\"/>\n");
out.write("<input type=\"hidden\" name=\"Sessionrequest\" value=\"" + true + "\"/>\n");
out.write("</form>\n</body>\n</html>\n");
}
}
In the above code the form should go to the servlet as mentioned in the actionUrl, but it is again going to servlet which is in step(1).
1) May i know can we make this above html form in step(3) to submitted and redirect to the servlet in **actionUrl**.
As per the above code i am summarizing the requirement. If the session is null, I have to redirect the user to login page and validated against database and then the response should go to step(1), Is it possible?
