Hello everyone I'm getting this error:
Uncaught exception: java.lang.IllegalArgumentException: Port Number formatted badly
- com.sun.midp.io.j2me.sms.Protocol.openPrimInternal(), bci=209
- com.sun.midp.io.j2me.sms.Protocol.openPrim(), bci=4

- javax.microedition.io.Connector.open(), bci=2
- travel.entities.SendMessage$1.run(SendMessage.java:31)

when converting those two textfields to send them
public TextField tfDestination = new TextField("Destination","", 20, TextField.PHONENUMBER);
public TextField tfPort = new TextField("Port", "50001", 6, TextField.NUMERIC);
using this method:
public static void execute(final String destination, final String port, final String message) {
Thread th = new Thread(new Runnable() {
public void run() {
MessageConnection msgConnection;
try {
msgConnection = (MessageConnection) Connector.open("sms://:"+port+":"+destination);
TextMessage textMessage = (TextMessage)msgConnection.newMessage(MessageConnection.TEXT_MESSAGE);
textMessage.setPayloadText(message);
msgConnection.send(textMessage);
msgConnection.close();
} catch (IOException e) {
e.printStackTrace();
}
}
});
th.start();
}
I'm getting the error on this line:
msgConnection = (MessageConnection)Connector.open("sms://:"+destination+":"+port);
Anyone have an idea?
Your destination should come before port number.
Try this:
public static void execute(final String destination, final String port, final String message) {
Thread th = new Thread(new Runnable() {
public void run() {
MessageConnection msgConnection;
String address = "sms://:"+destination+":"+port;
try {
msgConnection = (MessageConnection) Connector.open(address);
TextMessage textMessage = (TextMessage) msgConnection.newMessage(MessageConnection.TEXT_MESSAGE);
textMessage.setAddress(address);
textMessage.setPayloadText(message);
msgConnection.send(textMessage);
msgConnection.close();
} catch (IOException e) {
e.printStackTrace();
}
}
});
th.start();
}

I'm new to the quarkus framework where I'm writing rabbitmq-client library based on quarkur framework. I'm using io.quarkiverse.rabbitmqclient.RabbitMQClient.
I need to write JUnit for basic send and consume operations, please help me with how can I write junit and mock RabbitMQClient. I'm using the below code to send and consume message.
#ApplicationScoped
public class RabbitMQProducerAdapterImpl extends RabbitMQCongiguration implements RabbitMQProducerAdapter {
#Override
public void sendMessage(String exchange, String routingKey, String messagePayload) throws IOException {
setUpConnectionAndChannel();
channel.basicPublish(exchange, routingKey, null, messagePayload.getBytes(StandardCharsets.UTF_8));
Log.info("message sent succefully: " + messagePayload);
}
}
Here is the RabbitMQCongiguration
#ApplicationScoped
public class RabbitMQCongiguration {
#Inject
private RabbitMQClient rabbitClient;
protected Channel channel;
protected void setUpConnectionAndChannel() {
try {
// create a connection
Connection connection = rabbitClient.connect();
// create a channel
channel = connection.createChannel();
} catch (IOException e) {
throw new UncheckedIOException(e);
}
}
protected void setupQueueInDirectExchange(String exchangeName, String routingKey, String queueName,
boolean createExchangeQueues) throws IOException {
setUpConnectionAndChannel();
if (createExchangeQueues) {
this.channel.exchangeDeclare(exchangeName, BuiltinExchangeType.DIRECT, true, false, false, null);
// declaring a queue for this channel. If queue does not exist,
// it will be created on the server. this line not needed if queue already
// present
this.channel.queueDeclare(queueName, true, false, false, null);
}
// Bind Routing Key to Exchange
this.channel.queueBind(queueName, exchangeName, routingKey);
}
}
Below is the class for consumer
#ApplicationScoped
public class RabbitMQConsumerAdapterImpl extends RabbitMQCongiguration implements RabbitMQConsumerAdapter, Runnable {
private String queueName;
private MessageProcessor messageProcessor;
#Override
public void consumeMessage(String exchange, String queueName, String routingKey,

try {
this.queueName = queueName;
this.messageProcessor = messageProcessor;
Log.info("setting up rabbitMQPrefetchCountConfig");
setupQueueInDirectExchange(exchange, routingKey, queueName, false);
Thread consumerThread = new Thread(this);
consumerThread.start();
} catch (IOException e) {
throw new UncheckedIOException(e);
}
}
#Override
public void run() {
try {
// start consuming messages. Auto acknowledge messages.
Log.info("Start consuming messages from thread...");
channel.basicConsume(this.queueName, false, (Consumer) new DefaultConsumer(channel) {
#Override

if (body == null || body.length == 0) {
Log.warn("Invalid Message Body - Consumer Tag : " + consumerTag + ", Message DeliveryTag : "
+ envelope.getDeliveryTag());
channel.basicReject(envelope.getDeliveryTag(), false);
} else {
msgPayload = new String(body);
try {
JsonParser.parseString(msgPayload);
} catch (JsonSyntaxException ex) {
Log.error(msgPayload + " is not a valid json, Reason - ", ex);
channel.basicReject(envelope.getDeliveryTag(), false);
Log.warn("Rejected the current payload.");
return;
}
messageProcessor.processMessage(msgPayload);
channel.basicAck(envelope.getDeliveryTag(), false);
}
// just print the received message.
Log.info("Received: " + new String(body, StandardCharsets.UTF_8));
}
});
} catch (IOException e) {
throw new UncheckedIOException(e);
}
}
#ApplicationScoped
public class MessageProcessorImpl implements MessageProcessor{
#Override
public void processMessage(String messagePayload) {
Log.info("message consumed: " + messagePayload);
}
}
Can anyone can show me, with sample codes:
How to post JSON to a REST webservice; and
How to read the JSON response from the server;
Using Codename One?
Here is what i have tried which is returning bad request response from the server:
Button b1 = new Button("Add Staff");
b1.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent evt) {
JSONObject json = new JSONObject();
try {
ConnectionRequest post = new ConnectionRequest(){
#Override
protected void postResponse() {
try {
json.put("firstname", fname.getText());
json.put("middlename", mname.getText());
json.put("lastname", lname.getText());
json.put("dob", dob.getText());
json.put("gender", gender.getSelectedItem().toString());
json.put("marital", marital.getSelectedItem().toString());
json.put("phone", phone.getText());
json.put("adds", adds.getText());
json.put("username", user.getText());
json.put("password", pass.getText());
json.put("lat", lat.getText());
json.put("long", lon.getText());
} catch (JSONException ex) {
ex.printStackTrace();
}
}
#Override
protected void readResponse(InputStream input) throws IOException {
}
};
post.setUrl("http://localhost:8093/halimatbank/cbs/staff");
post.setPost(true);
post.setContentType("APPLICATION/JSON");
post.addArgument("body", json.toString());
boolean show = Dialog.show("Add Staff", "Are you Sure you want to add this Staff", "Yes", "NO");
NetworkManager.getInstance().addToQueueAndWait(post);
Map<String,Object> result = new JSONParser().parseJSON(new InputStreamReader(new ByteArrayInputStream(post.getResponseData()), "UTF-8"));
Map<String, Object> response = (Map<String, Object>)result.get("response");
Dialog.show("Staff Saved", ""+response, "OK","");
} catch (Exception ex) {
ex.printStackTrace();
}
}
});
postResponse() is invoked after the process completes. Not related to post itself. You want to override buildRequestBody which executes before. If I understand correctly you want the entire body to be the JSON and not an argument named "body" which is what you did...:
ConnectionRequest post = new ConnectionRequest(){
#Override
protected void buildRequestBody(OutputStream os) throws IOException {
os.write(json.toString().getBytes("UTF-8"));
}
#Override
protected void readResponse(InputStream input) throws IOException {
// parse response data
}
};
post.setUrl("http://localhost:8093/halimatbank/cbs/staff");
post.setPost(true);
post.setContentType("application/json");
I have finally overcome my issue with a NPE in my code whilst learning FX/FXML. I now however have a different problem, a window opens with my TableView however there is no content in the table at all. As you cann I have printed out the JobList to make sure there is content being returned, and this returns three jobs (the correct amount). Am I missing something that binds the table to the returned list?
Here is the code;
public class SecondInterface implements Initializable {
private JobDataAccessor jAccessor;
private String aQuery = "SELECT * FROM progdb.adamJobs";
private Parent layout;
private Connection connection;
#FXML
TableView<Job> tView;
public void newI(Connection connection) throws Exception {
Stage primaryStage;
primaryStage = MainApp.primaryStage;
this.connection = connection;
System.out.println(connection);
FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("Test1.fxml"));
fxmlLoader.setController(this);
try {
layout = (Parent) fxmlLoader.load();
} catch (IOException exception) {
throw new RuntimeException(exception);
}
primaryStage.getScene().setRoot(layout);
}
public Parent getLayout() {
return layout;
}
#Override
public void initialize(URL url, ResourceBundle rb) {
jAccessor = new JobDataAccessor();
try {
System.out.println("This connection: " + connection);
System.out.println("This query: " + aQuery);
List<Job> jList = jAccessor.getJobList(connection, aQuery);
for (Job j : jList) {
System.out.println(j);
}
tView.getItems().addAll(jAccessor.getJobList(connection, aQuery));
} catch (SQLException e) {
e.printStackTrace();
}
}
}
I'm developing an Android App and i create a slide menu. In the slide menu i have item "Search". This is a fragment that call a json (using volley) and input the result into custom list view.
