I am trying to send a string from struts action in one application to
servlet in another application. However, the following code doesn't work and
no string is received. If I try replace service() with doPost() or doGet(),
doPost() will give exception but doGet() won't. It seems that the request is
not a Post request therefore open an InputStream from the request will fail.
How could I create a Post request from struts action?
Sending side:
public class SubmitAction extends Action {
public ActionForward perform(){
String string = " ********";
String toURL =
"http://localhost:8080/AnotherApp/servlet/servlets.ControllerServlet";;
URL url = new URL(toURL);
URLConnection con = url.openConnection();
con.setDoOutput(true);
con.setDoInput(true);
con.setUseCaches (false);
con.setDefaultUseCaches (false);
con.setRequestProperty("Content-Type", "text/html");
con.setRequestProperty("Content-length", "" + string.length());
OutputStream outStream = con.getOutputStream();
OutputStreamWriter ostream = new OutputStreamWriter(outStream);
BufferedWriter out = new BufferedWriter(ostream);
out.write(string);
outStream.flush();
outStream.close();
return new ActionForward(toURL, true);
}
}
Receiving side:
public class ControllerServlet extends HttpServlet {
public void service(){
InputStream in = request.getInputStream();
InputStreamReader rdr = new InputStreamReader(in);
BufferedReader buff = new BufferedReader(rdr);
String line;
StringBuffer results = new StringBuffer();
while (null != ((line = buff.readLine())))
results.append(line + "n");
buff.close();
String resultString = results.toString();
}
}
