This is probably a common question but I can't figure it out.
I have this URL which returns the expected ticket detail if I plug it into a browser, so I know it is working:
https://www.myconnectwise.net/v4_6_release/services/system_io/integration_io/processClientAction.rails?actionString=%3C%3Fxml%20version%3D%221.0%22%20encoding%3D%22utf-16%22%3F%3E%0A%3CGetTicketAction%20xmlns%3Axsi%3D%22http%3A%2F%2Fwww.w3.org%2F2001%2FXMLSchemainstance%22%20xmlns%3Axsd%3D%22http%3A%2F%2Fwww.w3.org%2F2001%2FXMLSchema%22%3E%0A%3CCompanyName%3Exxxxxxx%3C%2FCompanyName%3E%3CIntegrationLoginId%3Exxxxxx%3C%2FIntegrationLoginId%3E%3CIntegrationPassword%3Exxxxxx%3C%2FIntegrationPassword%3E%0A%3CSrServiceRecid%3E1921%3C%2FSrServiceRecid%3E%3C%2FGetTicketAction%3E
For a more readable version it is this URL:
https://www.myconnectwise.net/v4_6_release/services/system_io/integration_io/processClientAction.rails
Followed by:
?actionString=
Followed by this xml:
<?xml version="1.0" encoding="utf-16"?>
<GetTicketAction xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<CompanyName>xxxx</CompanyName><IntegrationLoginId>xxxx</IntegrationLoginId><IntegrationPassword>xxxx</IntegrationPassword>
<SrServiceRecid>1921</SrServiceRecid></GetTicketAction>
I am having problems putting this into code and getting it to work.
I get this error:

I have got 'Server returned HTTP response code: 500 for URL: myconnectwise.net/v4_6_release/services/system_io/…; after executing of your code.
So check server (500 - Internal Server Error).
And analyze response code before parsing result as XML.

just placing the query in the browser returns a response but through my program, I get an error. If someone can hellp I would be grateful.
Im creating a rest service
First you have to use InputStream since you are reading data from the response. Second, you have to accept as json response for that you have to use conn.setRequestProperty("Accept", "application/json");
I have modified your program, please check.
public class PopulationService {
public static void getPopulation() {
String query_url =
"https://data.opendatasoft.com/api/records/1.0/search/?dataset=world-population#kapsarc&facet=country_name&facet=year&refine.country_name=Australia&refine.year=2000";
try {
URL url = new URL(query_url);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestProperty("Accept", "application/json");
conn.setDoOutput(true);
conn.setRequestMethod("GET");
conn.connect();
BufferedReader br = new BufferedReader(new InputStreamReader(
(conn.getInputStream())));
String output;
System.out.println("Response Server .... \n");
while ((output = br.readLine()) != null) {
System.out.println(output);
}
conn.disconnect();
int status = conn.getResponseCode();
System.out.println("Status Code: "+status);
} catch (Exception e) {
System.out.println(e);
}
}
public static void main(String args[]) {
getPopulation();
}
}
I am trying to get a token for an API with this code and it throws exception when it tries to get and check the response code. It is my understanding that url.openConnection() does not actually connect? I tried url.connect() but that didn't work for me. When I
System.out.println(conn);
i just get this:
sun.net.www.protocol.https.DelegateHttpsURLConnection:https://fim.api.ENV.fleetmatics.com/token
and when I
System.out.println(conn.getResponseCode());
I do not get anything.
public TokenGenerator(String username, String password, String getTokenUri){
_username = username;
_password = password;
_getTokenUri = getTokenUri;
_authString = GetToken();
}
private String GetToken(){
String authString = "";
try
{
// Get authentication, Base64 encoded, string
String basicAuth = BuildBasicAuth(_username, _password);
URL url = new URL(_getTokenUri);
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.setRequestProperty("Authorization", basicAuth);
conn.setRequestProperty("Accept", "text/plain");
conn.setDoOutput(false);
// Execute request;, read response. If we do not receive a 200 OK, throw exception
if (conn.getResponseCode() != HttpsURLConnection.HTTP_OK) {
throw new RuntimeException("Failed : HTTP error code : " + conn.getResponseCode());
}
When I try to connect with this code, I get the stack trace below..
HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
conn.connect();
conn.setRequestMethod("GET");
conn.setRequestProperty("Authorization", basicAuth);
conn.setRequestProperty("Accept", "text/plain");

Thanks in advanced.
I was facing this problem continuously since last 9 hrs but now i found the solution.
There is no error in code implementation but my firewall was not let them go to connect.
When i was turned off my firewall from control panel then all code works perfectly.
Thanks you
I am programming on a system with client running Java Applet on one end and server on the other. Now I have the client and server on the same computer. But as a client, I cannot see the applet and I get error like below:

Below is where the problem traced back:
URL url = new URL(ipAddr);
URLConnection connection = url.openConnection();
connection.setDoOutput(true);
OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream()); // exception happens
I checked http://localhost:8080/ and port conflict. I have turn off windows firewall and yet the problem exists. Can someone kindly point me some direction? Any advice would be great! Thanks ahead!
I apologize for the long code. The first is for client.

Based off your comments my guess is that your server is binding to the loopback address (127.0.0.1, aka localhost). You didn't post what the server software is, but change it's configuration so that it binds on 0.0.0.0 instead. That should fix your issue.
HI I am having problem in java related to write on the web server from the client. I am using following code please help me where I am wrong
For Server class
import java.net.ServerSocket;
import java.net.Socket;
import java.io.InputStream;
import java.util.Scanner;
import java.io.InputStreamReader;
import java.io.BufferedReader;
public class Server
{
public static void main(String args[]){
try{
ServerSocket s = new ServerSocket(8080);
System.out.println("ashish");
Socket incoming = s.accept();
System.out.println("the status of the socket="+incoming.isConnected());
InputStream inStream = incoming.getInputStream();
InputStreamReader isr=new InputStreamReader(inStream);
BufferedReader br=new BufferedReader(isr);
String str=null;
while((str=br.readLine()).equals("exit")==false){
System.out.println(str);
}
System.out.println("System exit");
}catch(Exception e){
e.printStackTrace();
}
}
}
And for the client class which is actually applet have folowing code
import java.applet.Applet;
import java.net.URL;
import java.net.HttpURLConnection;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
public class testApplet extends Applet
{
public void init(){}
public void start(){
try{
URL url = new URL("http://localhost:8080");
HttpURLConnection httpCon = (HttpURLConnection)url.openConnection();
httpCon.setDoOutput(true);
httpCon.setRequestMethod("PUT");
PrintWriter out = new PrintWriter( httpCon.getOutputStream());
out.print("Resource content\n");
out.print("exit");
out.close();
}catch(Exception e){
e.printStackTrace();
}
}
public void stop(){}
public void destroy(){}
}
Now when I run the server then the server display only the following
PUT / HTTP/1.1
User-Agent: Mozilla/4.0 (Windows Vista 6.1) Java/1.6.0
Host: localhost:8080
Accept: text/html, image/gif. image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive
But it did not write the content which I write by the out object of PrintWriter
and next goes into wait state
on the other hand the applet does not started just initiated. and when I close server program then applet gives following exception
java.net.ConnectException: Connection refused: connect
at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.PlainSocketImpl.doConnect(Unknown Source)
at java.net.PlainSocketImpl.connectToAddress(Unknown Source)
at java.net.PlainSocketImpl.connect(Unknown Source)
at java.net.Socket.connect(Unknown Source)

at java.net.HttpURLConnection.getResponseCode(Unknown Source)
at testApplet.start(testApplet.java:19)
at sun.applet.AppletPanel.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
Please tell what's wrong with me
Try
httpCon.setChunkedStreamingMode(0);
before writing to outputstream. You should always do this on http connections if content length is not known in advance.
