Hi guys,

I have my android phone and laptop connected to the same wifi network.

Just want to ask if there is a way my android app knows my laptop's IPV4 address?

I want to call a php script within the laptop's localhost server.

Your responses are very much appreciated!

Thank you.

So here's the situation:

I want to put my table inside a form for retrieval purposes (or Am i doing it wrong?)
When the table is not within a form, it works perfectly. It displays information the way i wanted.
However, once I put the table inside a form the table doesn't display needed information.

Is the problem the html or the jsp code?

Here's my jsp file:


<form action="deletemovie" method="GET" id="deleteForm"> <table class="table table-striped table-responsive table-hover"> <thead> <tr> <td>Movie ID</td> <td>Movie Title</td> <td>Movie Rating</td> <td>Movie Genra</td> </tr> </thead> <% List<Movies> moviesList = (List<Movies>) request.getAttribute("movies"); for(Movies m : moviesList){ %> <tr> <td><a href="#" name="movieId" value=<%=m.getMovieId()%>> <input type="checkbox" name="selectedMovies"/> <%=m.getMovieId()%> </a></td> <td><%=m.getMovieTitle()%></td> <td><%=m.getMovieRating()%></td> <td><%=m.getMovieGenre()%></td> </tr> <% } %> </table> </form>

Thank you very much!

Hi guys.

I just want to to ask how can I send a form to a servlet using javascript?

Here's my form:

<form id="movieForm" class="form-signin" action="addnewmovie" method="POST" enctype="multipart/form-data"> <h1 class="text-center movie-title">Add New Movie</h1> <div class="row"> <div class="col-md-12"> <input id="movieId" type="text" class="input-hide form-control" placeholder="Movie ID"> </div> </div> <div class="row"> <div class="col-md-12"> <input id="movieTitle" type="text" class="input-hide form-control" placeholder="Movie Title" /> </div> </div> <div class="row"> <div class="col-md-12"> <input id="movieRating" type="text" class="input-hide form-control" placeholder="Movie Rating" /> </div> </div> <div class="row"> <div class="col-md-12"> <select id="drop" class="input-medium form-control"> <% List<Genra> list = (List<Genra>) request.getAttribute("genra"); for(Genra g : list){ %> <option><%=g.getGenraName()%></option> <% } %> </select> </div> </div> <div class="row"> <div class="col-md-4"> <label>Add Image</label> <input id="browse" type="file"> </input><br /> </div> </div> </form>


This button will responsible for sending:

<button id="add-new-movie" class="button-position btn btn-primary btn-block" type="submit" onClick="submitForm();">Add Movie</button>

Note that I include file uploading in the form.

Thank you very much!

Your responses will be much appreciated!

Hey guys,

still can't connect even i supplied android permission to use net.

@Ulf Ditmer - what I mean is I used my physical handphone for testing and I am connected to the network through Wifi.

@Maneesh Godbole - not yet sir, i'll try it =)

Thanks for your reply.

Hello guys.

I am new to android programming.

I tried to access the localhost in my laptop using my android phone.

To check the connection I supply thiis code:

try {
HttpClient httpclient = new DefaultHttpClient();


HttpPost httppost = new HttpPost(
"http://10.0.2.2/ssmis/acess1.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
System.out.println("connected!");
} catch (Exception e) {
Log.e("log_tag", "Error in http connection" + e.toString());
}

However the logcat gives me an error that says that I have error in HttpConnection and that the connection is refused.

I also tried to supply many addresses in HttPost Constructor but nothing worked like http://192.168.10.7/ (which is my IPv4 address)

Note that I used my android phone as emulator and I am not using AVD.

So what should I do?

Your responses will be very much appreciated.

Thank you!

Hello guys,

So what do you think is wrong with these?

Your reply will be much appreciated.

What are the things I needed to get started?

Is Apache Tomcat enough?

Ok,

I think I just have to study web service. =)

Can you please give me summary of steps that I should do?

Good day!

I have a desktop application which I made using javafx and a database connection to a localhost server.

What I want to do is to have an online database and my desktop application can access that database.

In addition, I would also like to develop an android application that access the same database.

Can I do the connection to database without using web service in java?

How?

Your answers will be very much appreciated.

Cheers!

Hi,

Thank you for the reply.

I am gonna use the code for my school's project. My project includes a module where I want to register new task for each employee and tracking each one of them.
I already managed to write a code where the progressbar is in TableView. I also managed to create Task object and bind its progress to the progressbar.

But I think service will do well with the help of the Executor you are referring with. In oracle documentation it said that it can be restarted and scheduled.

The problem now is, I dont know how to implement Service and Executor.

Would you mind if you provide some sample codes? I will appreciate it so much since I am just a student and found it hard to understand the API documentation.

Thank you so much!

Good day!

So I wrote a program showing all employees and their current progress in each task they assigned.
I already managed to add ProgressBar on my TableCells (hoping I made the right way).

What I wanted now is when I select certain employee in the table and click the "Start" button the task should start and the progressbar should work.

How can I do that? Here's my two classse:

public class MainScreenController implements Initializable { @FXML private TableView<EmployeeTaskStatus> tbl; @FXML private TableColumn<EmployeeTaskStatus, String> nameCol; @FXML private TableColumn<EmployeeTaskStatus, Double> progressCol; private ObservableList<EmployeeTaskStatus> list = FXCollections.observableArrayList(); @Override public void initialize(URL url, ResourceBundle rb) { list.add(new EmployeeTaskStatus("JC Frane", 0.00)); list.add(new EmployeeTaskStatus("Catherine Paredes", 0.00)); nameCol.setCellValueFactory(new PropertyValueFactory("name")); progressCol.setCellValueFactory(new PropertyValueFactory("progress")); progressCol .setCellFactory(ProgressBarTableCell.<EmployeeTaskStatus>forTableColumn()); tbl.setItems(list); } @FXML public void startTask(ActionEvent ev) { //code here } }

public class EmployeeTaskStatus { private StringProperty name; private DoubleProperty progress; private BooleanProperty isReady; private BooleanProperty isFinished; public EmployeeTaskStatus(String name, double progress) { this.name = new SimpleStringProperty(name); this.progress = new SimpleDoubleProperty(progress); } public StringProperty nameProperty() { return this.name; } public DoubleProperty DoubleProperty() { return this.progress; } }

Badly needed guys.

Thank you very much!

Good day!

Can I use Thread class in javafx or should I use Task and Service class?

Thank you!

Instead of fading out you might want to slide the panel instead???

This might help you:

Good Day!

So I am new into reporting in java.
I am using Netbeans for coding and Jaspersoft Studio for generating jrxml files. (My jdk is 1.8)

When I try to click a button and try to view the report in give me something like this:

log4j:WARN No appenders could be found for logger (net.sf.jasperreports.engine.xml.JRXmlDigesterFactory).
log4j:WARN Please initialize the log4j system properly.
net.sf.jasperreports.engine.JRException: Error loading object from file : C:\Users\JC\Documents\Simple_Blue.jrxml

I think the two lines are just normal however the JREException may be not, This is my whole code:

public class ReportingDemo extends Application { Connection conn = null; @Override public void start(Stage primaryStage) { try { conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/sample", "root", "shinobi015"); System.out.println("Connected to the database!"); } catch (SQLException ex) { System.out.println("Error\n" + ex); } Button btn = new Button(); btn.setText("Say 'Hello World'"); btn.setOnAction(new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent event) { try { //String report = "Simple_Blue.jrxml"; String report = "C:\\Users\\JC\\Documents\\Simple_Blue.jrxml"; JasperReport jr = JasperCompileManager.compileReport(report); JasperPrint jp = JasperFillManager.fillReport(report, null,conn); JasperViewer.viewReport(jp); } catch (Exception ex) { System.out.println(ex); } } }); StackPane root = new StackPane(); root.getChildren().add(btn); Scene scene = new Scene(root, 300, 250); primaryStage.setTitle("Hello World!"); primaryStage.setScene(scene); primaryStage.show(); } /** * @param args the command line arguments */ public static void main(String[] args) { launch(args); } }

Any help will be so much appreciated!

Thank you!
