I use TextArea in a "for" code block
for (String s:List){
executor.execute(new Runnable() {
#Override
public void run() {
try {
textarea.appendText(s);
} catch (IOException ignore) {}
}
});
}
TextArea is not thread safe, i read this page pageso i tried
public void changeArea(TextArea area, String text){
synchronized(area) {
area.appendText(text);
}
}
I modify my "for" block
changeArea(textarea, "sth");
When I run the code,java continues to give me a mistake

I tried "lock" and add "synchronized" in the changearea method
When I delete
textarea.appendText(s)
and replace
system.out.println(s)
, its ok.I thought this is a Multithreading safe issues
When i change my code
public synchronized void changeArea(TextArea area, String text){
area.appendText(text);
}
java point out

I faced a weird issue and it is just like a dead-lock. When i call a dao method to save an entity into oracle db, hibernate never respond and thread never comes back. My aim is to save a row when exception is cached. However, Hibernate neither throws exception nor do its job. Just waiting forever(Thread has been waiting for 3 days). Is there any idea about the problem? what did i implement wrong?

Have a Java servlet running using a Tomcat server. So when the servlet starts, I would like the client to connect to a RMI registry (Port 33996). The client is initialized during the init() of the servlet. However, for some reason, it is unable to connect to the server
Server code
#Override
public void startRMIRegistry(CentralServer server){
try {
AsyncLogger.log("Setting up RMI Registry.....");
Registry registry = LocateRegistry.createRegistry(
Integer.parseInt(ServerConfigUtils.getProperty(ServerConfigUtils.PORT)));
registry.rebind(ServerConfigUtils.getProperty(ServerConfigUtils.NAME), server);
} catch (RemoteException e) {
e.printStackTrace();
}
}
Client code
private ICentralServer getServerConnection() {
String serverHost = ServerConfigUtils.getProperty(ServerConfigUtils.HOST);
Integer serverPort = Integer.valueOf(ServerConfigUtils.getProperty(ServerConfigUtils.PORT));
String serverName = ServerConfigUtils.getProperty(ServerConfigUtils.NAME);
Integer failureCount = 0;
while (failureCount < SERVER_ACTION_ATTEMPTS) {
try {
return (ICentralServer)
LocateRegistry.getRegistry(serverHost, serverPort).lookup(serverName);
} catch (Exception e) {
failureCount++;
continue;
}
}
AsyncLogger.log("Failed to connect to central server, giving up");
throw new RuntimeException();
}
Servlet
#Override
public void init() throws ServletException {
try {
client = new LabClient();
} catch (Exception e) {
e.printStackTrace();
}
super.init();
}

Had my peers tried this code, they were all able to connect successfully.
Have tried toggling off firewall, setting inbound rules to the port but to no avail
Found the solution, I ran mvn clean package at the parent maven directory, previously I was rebuilding the sub-modules invidually at sub-module level, which corrupted the bytecode.

Context: Lab using the google transit GTFS API. Using a table view to display route data, and I want to make the data editable from the table. I've succeeded in doing that when the property is a String(route ID and route long name), but the code that makes a cell editable throws an error for non-String properties.
Table Code:
table = new TableView<>();
ObservableList data = FXCollections.observableList(routes);
table.setItems(data);
table.setEditable(true);
Code for color data column:
TableColumn routeColorCol = new TableColumn("Route Color");
routeColorCol.setCellValueFactory(new PropertyValueFactory("route_color"));
routeColorCol.setCellFactory(TextFieldTableCell.forTableColumn());
routeColorCol.setOnEditCommit(new EventHandler<TableColumn.CellEditEvent>() {
#Override
public void handle(TableColumn.CellEditEvent t){
((Route) t.getTableView().getItems().get(
t.getTablePosition().getRow())
).setRoute_color((Color)t.getNewValue());
}
});
I add the table to a Vbox and onto a tab pane. The stacktrace I get doesn't point anywhere to my code, so I'm at a loss.

You have used raw type which has made this possible to compile, but type inconsistency happened during runtime. Your routeColorCol is supposed to display javafx.scene.paint.Color values, but your cell factory callback is written to read String values - this is what caused the ClassCastException at runtime.
From TextFieldTableCell.forTableColumn():
Provides a TextField that allows editing of the cell content when the
cell is double-clicked, or when TableView.edit(int,
javafx.scene.control.TableColumn) is called. This method will only
work on TableColumn instances which are of type String.
You should use the overload method TextFieldTableCell.forTableColumn(StringConverter).
routeColorCol.setCellFactory(
TextFieldTableCell.<Foo, Color> forTableColumn(new StringConverter<Color>() {
#Override
public String toString(Color object) {
return object != null ? object.toString() : "";
}
#Override
public Color fromString(String string) {
return Color.valueOf(string);
}
}
));
I have a partitioned job that reads from and writes to a DB. I have a chunking size of 10. If a partition fails and i want the restart to happen from the last commit, I have overwritten the checkpointinfo method and wrote my logic according to my application requirement. whenever i try to restart the failed job, i am getting an exception that there is failure in Read-Process-Write Loop
Here is the exception logs:
[3/1/18 19:18:09:004 IST] [process partition0] com.ibm.ws.batch.JobLogger CWWKY0030I: An exception occurred while running the step process.

This is because of the BigInteger Datatype used in oracle.
This appears to be a bug in Liberty. Opened issue #2792.
I think it will happen with any array type, and that you could workaround by using an ArrayList in place of an array.
UPDATE: A fix for this issue was delivered in 18.0.0.2.
I am trying to listen to an endless stream from meetups open_events streaming API. For some reason I get a socketTimeoutException after (what seems to be) a random period of time. My code works for the meetups rsvps streaming API. I am using a okio.BufferedSource as you can see below. I get the exception for "while (!source.exhausted())", but when writing "while (true)" instead gives the exception on the line below. The difference between rsvps and open_events as far as I can see is that rsvps uses long polling and returns an array, and open_events uses chunked transfer encoding to maintain a persistent connection. Is the problem that I cannot use BufferedSource for chunked responses, and what should I then use instead?
public static Observable<String> events(BufferedSource source) {
return Observable.create(new Observable.OnSubscribe<String>() {
#Override
public void call(Subscriber<? super String> subscriber) {
try {
while (!source.exhausted()) {
subscriber.onNext(source.readUtf8Line());
}
} catch (IOException e) {
e.printStackTrace();
subscriber.onError(e);
}
subscriber.onCompleted();
}
});

This might not be related but further down the error stack there is a mention of Add onError handling. Maybe you need to add this method to your implmentation?
