How is it called?

Well I removed it completely as I didn't know how to get it work, it always returnet me NULL object.

I am trying to get JSON from RPC and I am keep getting error:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.cryptowallet/com.example.cryptowallet.UserProfile}: android.os.NetworkOnMainThreadException

I found out that application is crashing at line:

HttpResponse response = httpclient.execute(httppost);


Full code looks like:

private JSONObject invokeRPC(String id, String method, List<String> params) {        DefaultHttpClient httpclient = new DefaultHttpClient();        JSONObject json = new JSONObject();        json.put("id", id);        json.put("method", method);        if (null != params) {            JSONArray array = new JSONArray();            array.addAll(params);            json.put("params", params);        }        JSONObject responseJsonObj = null;        try {            httpclient.getCredentialsProvider().setCredentials(new AuthScope("http://blockchain.oss.unist.hr", 8332),                    new UsernamePasswordCredentials("student", "WYVyF5DTERJASAiIiYGg4UkRH"));            StringEntity myEntity = new StringEntity(json.toJSONString());            System.out.println(json.toString());            HttpPost httppost = new HttpPost("http://blockchain.oss.unist.hr:8332");            httppost.setEntity(myEntity);            System.out.println("executing request" + httppost.getRequestLine());            //Problem ispod            //_____________________________________________________            HttpResponse response = httpclient.execute(httppost);            //_____________________________________________________            HttpEntity entity = response.getEntity();            System.out.println("----------------------------------------");            System.out.println(response.getStatusLine());            if (entity != null) {                System.out.println("Response content length: " + entity.getContentLength());                // System.out.println(EntityUtils.toString(entity));            }            JSONParser parser = new JSONParser();            responseJsonObj = (JSONObject) parser.parse(EntityUtils.toString(entity));        } catch (ClientProtocolException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (ParseException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (org.json.simple.parser.ParseException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } finally {            httpclient.getConnectionManager().shutdown();        }        return responseJsonObj;    }

I tried to put it in Asynctask but I didn't know how to do it, all attempts failed.

public Connection getConn() {    return Conn; } public int getUser() {    return User; } Then you could use them with a Class2 object:
Class2 foo = new Class2(Conn, MyUserID); // ... int userId = foo.getUser(); Also note that variables should start with a lowercase letter.

I must be doing something wrong but I still didn't make it work, tought it would be much easier to return parameter from GUI to GUI in JAVA.
Now I am  thinking to use text file as "Temp" and on return from Class2 to Class1 read variable from text file (Not best solution but should do a trick).

Thank You for Your replays.

How should I call GUI class and return selected parameter from it?
What method should I use for that?

Well I am not sure, I know that when I am calling another GUI class I do it like that so I tought I am sendig parameters in first line and than I am setting it visible with returning parameter.

How shouold I call it to send 2 parameters and return one into integer?

Hey all,

There is something that bother me.

I am working in NetBeans and JAVA Swing.

I have 2 classes ("Class 1" and "Class 2"). Both of classes has "GUI".
So I want when I click on label in "Class 1" call "Class 2". "Class 2" will on bottun click return some parameter. I am also sending some parameters from "Class 1" to "Class 2".

Class 1 call Example:

   private void vrstaOpremeMouseClicked(java.awt.event.MouseEvent evt) {                                                Class2 tipOpreme = new Class2(Conn, MyUserID);        int myTipOpreme = 3;        myTipOpreme = tipOpreme.setVisible(true);            }      

Class 2 Example:

import java.sql.Connection; import java.sql.ResultSet; import javax.swing.event.ListSelectionEvent; import net.proteanit.sql.DbUtils; /** * * @author josips */ public class Class2 extends javax.swing.JFrame {    private Connection Conn;    private int User;    String userIme;    String userPrezime;    String userUsername;    String rowClicked = null;    int rowClickedInt = 0;    int myTempID = 0;    //Spajanje na bazu    IzvrsavanjeSkriptiNaBazi CALIzb = new IzvrsavanjeSkriptiNaBazi();    ResultSet RS = null;    /**     * Creates new form AdminTicketi     * @param con     * @param user     * @return     */    public Class2(Connection con, int user) {        this.Conn = con;        this.User = user;        initComponents();        GetUser(User);        AddActionListener();        return myTempID;    }                                                            private void btn_PrihvatitiActionPerformed(java.awt.event.ActionEvent evt) {                                                      System.out.println(rowClickedInt);    }                                               }


In class1 I am getting error on line:

myTipOpreme = tipOpreme.setVisible(true);

incompatible types: void cannot be converted to int

So in the Class2 I add "int":

   public int TipOpreme(Connection con, int user) {        this.Conn = con;        this.User = user;        initComponents();        GetUser(User);        AddActionListener();        return myTempID;    }

So when I click on button in class2 it will populate myTempID and return it.

But now I am getting error on 2 lines in Class1:

TipOpreme tipOpreme = new TipOpreme(Conn, MyUserID);

constructor TipOpreme in class TipOpreme cannot be applied to given types;
 required: no arguments
 found: Connection,int
 reason: actual and formal argument lists differ in length

myTipOpreme = tipOpreme.setVisible(true);

incompatible types: void cannot be converted to int

I am not sure what am I doing wrong?

I am sorry for 3 posts in row, I am not able to edit (Or I don't know how) posts to add updates.

Anyway, here is solution:

       tableNogomet.getSelectionModel().addListSelectionListener((ListSelectionEvent event) -> {            if (!event.getValueIsAdjusting()) { <---------------- I added this line                //Get row to int                rowClicked = tableNogomet.getValueAt(tableNogomet.getSelectedRow(), 0).toString();                rowClickedInt = Integer.parseInt(rowClicked);                //Get col to int                colClickedInt = tableNogomet.getSelectedColumn();                CALRegistration.UpisivanjeNaTempTicket(rowClickedInt, colClickedInt, MyUserID, Conn);                PostavljanjeTablica();            }        });

   private void AddActionListener() {        UpisivanjeNaTempTicket CALRegistration = new UpisivanjeNaTempTicket();        tableNogomet.getSelectionModel().addListSelectionListener((ListSelectionEvent event) -> {  // I think that problem is in this line            //Get row to int            rowClicked = tableNogomet.getValueAt(tableNogomet.getSelectedRow(), 0).toString();            rowClickedInt = Integer.parseInt(rowClicked);            //Get col to int            colClickedInt = tableNogomet.getSelectedColumn();            CALRegistration.UpisivanjeNaTempTicket(rowClickedInt, colClickedInt, MyUserID, Conn);           //  PostavljanjeTablica(); //        });

This is the part of code that make "doubles".  Now it is time for me to find out how to fix it .

So then you still haven't told us the statement that is causing the problem!!! How do you expect us to help?

I noticed that everything is executed twice

So you have a bug in your code somewhere. Time to do some debugging.

Yeah, sometimes when You write it down it is easier to notice the problem. Best way is to tell someone about it and it is easier find it.

Anyway, as soon as I find something useful, or solution, I'll post it.

So get rid of the

table.setModel( new DefaultTableModel() );

Thank You for suggestion, tried that but still same error.

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: -1

I noticed that everything is executed twice, even when I limit it with for loop, so I can't find reason why is that, I guess that the first time is executed and than it is trying execute empty SQL query, but it still should execute same query twice without any problem as it is only select.

Does that tell us where the exception was thrown? Please answer RC's question.

As I tracked it down I think it break at:

  tableTemp.setModel(new DefaultTableModel()); <-- This line        RS = CALIzb.main(Conn, "select F09PRK ID, F09TIM1 Domacin, F09TIM2 Protivnik, F09TIP Tip, F09KOE Koeficijent from temp_ticket where F09UID = '" + MyUserID + "' ORDER BY F09DVT ASC");        tableTemp.setModel(DbUtils.resultSetToTableModel(RS));

And I tried many ways to clear table and still always break there. So I am not sure is there problem at all and why it breaks.

Rob Camick wrote:Well we have no idea which statement is causing the Exception, so how do you expect us to help?

Yeah, sorry, I'll describe it more precisely.

This is betting application where I generate random "games" trough Microsoft SQL script (Random time).
When user run software it checks if there are games for that day in SQL Table, if not generate them for next 7 days.

Than user is coming to Login\Registrate screen. After successful login I have 4 jtables (Soccer, Basketball,...) that are filled up with selected data (SQL code).

   private void FillTableWithData(String Time) {        try {            //Soccer            RS = CALIzb.main(Conn, "select F07IDP ID, F07TM1 Domacin, F07TM2 Protivnik, F07KO1 '1', F07KOX X, F07KO2 '2', REPLACE( F07VRI, RIGHT(F07VRI, 11), '' ) Vrijeme from parovi where F07SPO = '1' and F07DTI = '" + Time + "' ORDER BY F07VRI ASC");            tableNogomet.setModel(DbUtils.resultSetToTableModel(RS));            //Fill TEMP table            PostavljanjeTablica();        } catch (Exception ex) {            ex.printStackTrace();        }    }


So "CALIzb.main" is calling new class that is working with SQL queries:

public class IzvrsavanjeSkriptiNaBazi {    private Connection CONN;    private String SQL;    ResultSet rs;    public  ResultSet main(Connection conn, String sql) {        this.CONN = conn;        this.SQL = sql;        System.out.println(SQL);        try {            Statement stmt = CONN.createStatement();            rs = stmt.executeQuery(SQL);        } catch (SQLException e) {        }                return rs;    } }

And the " //Fill TEMP table PostavljanjeTablica();" is calling method that is filling Temp Table. Temp table is table that are saving games that user selected. It is refreshed with every game that user select.

       tableTemp.setModel(new DefaultTableModel());        RS = CALIzb.main(Conn, "select F09PRK ID, F09TIM1 Domacin, F09TIM2 Protivnik, F09TIP Tip, F09KOE Koeficijent from temp_ticket where F09UID = '" + MyUserID + "' ORDER BY F09DVT ASC");        tableTemp.setModel(DbUtils.resultSetToTableModel(RS));

Also if user change date with jcalendar all table has to refresh data:

   private void btnPotvrdiActionPerformed(java.awt.event.ActionEvent evt) {                                                  // TODO add your handling code here:        tableNogomet.setModel(new DefaultTableModel());        tableKosarka.setModel(new DefaultTableModel());        tableHokej.setModel(new DefaultTableModel());        tableTenis.setModel(new DefaultTableModel());        sd = dateFormat.format(pickDate.getDate());         FillTableWithData(sd);    }  

So everything is working fine untill I change date and try to add new games, or If I try to delete one game from jtable on temp ticket.

I am adding new games on temp ticket with:

   private void AddActionListener() {        UpisivanjeNaTempTicket CALRegistration = new UpisivanjeNaTempTicket();        //Soccer        tableNogomet.getSelectionModel().addListSelectionListener(new ListSelectionListener() {            public void valueChanged(ListSelectionEvent event) {                //Get row to int                rowClicked = tableNogomet.getValueAt(tableNogomet.getSelectedRow(), 0).toString();                rowClickedInt = Integer.parseInt(rowClicked);                //Get col to int                colClickedInt = tableNogomet.getSelectedColumn();                CALRegistration.UpisivanjeNaTempTicket(rowClickedInt, colClickedInt, MyUserID, Conn);                PostavljanjeTablica();            }        });}

And I am deleting selected game from jtable:

   private void brisiParTempActionPerformed(java.awt.event.ActionEvent evt) {                                                    // TODO add your handling code here:        RS = CALIzb.main(Conn, "delete from Temp_Ticket where F09PRK = '" + tempClickedInt + "'");        PostavljanjeTablica();    }  

"PostavljanjeTablica()" looks like:

   public void PostavljanjeTablica() {        PunjenjeTempTablice(); //This is problem        PostavljanjeBrojaParova();        PostavljanjeKoeficijenta();        PostavljanjePDVnaIznos();        PostavljanjeUkupnogDobitka();        IzracunPorezaNaUkupno();        PostavljanjeIznosaIsplate();    }

Hey all,

I am having problem with clearing jtable and filling it again with data:

   private void PunjenjeTempTablice() {                //tableTemp.setModel(new DefaultTableModel()); - Tried this too        DefaultTableModel model = (DefaultTableModel) tableTemp.getModel();        model.setRowCount(0);        RS = CALIzb.main(Conn, "select F09PRK ID, F09TIM1 Domacin, F09TIM2 Protivnik, F09TIP Tip, F09KOE Koeficijent from temp_ticket where F09UID = '" + MyUserID + "' ORDER BY F09DVT ASC");        tableTemp.setModel(DbUtils.resultSetToTableModel(RS));    }

Error that I am getting:

java.lang.ArrayIndexOutOfBoundsException: -1

Hey all,

I am making password recovery module for my software where I need send user data through user mail.

My code is:

import java.sql.Connection; import java.util.Properties; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.PasswordAuthentication; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; public class MailRecovery {    public void MailRecovery(Connection conn, String recoveryMail, String recoveryPassword, String recoveryUsername) {        final String username = "********@gmail.com";        final String password = "******";        Properties props = new Properties();        props.put("mail.smtp.starttls.enable", "true");        props.put("mail.smtp.auth", "true");        props.put("mail.smtp.host", "smtp.gmail.com");        props.put("mail.smtp.port", "587");        Session session = Session.getInstance(props,                new javax.mail.Authenticator() {            protected PasswordAuthentication getPasswordAuthentication() {                return new PasswordAuthentication(username, password);            }        });        try {            Message message = new MimeMessage(session);            message.setFrom(new InternetAddress("******@gmail.com"));            message.setRecipients(Message.RecipientType.TO,                    InternetAddress.parse(recoveryMail));            message.setSubject("*** - Password Recovery");            message.setText("Username: " + recoveryUsername                    + "\n Password: " + recoveryPassword);            Transport.send(message);            PopError CALError = new PopError();            CALError.infoBox("Podaci su poslani na mail!", "Success!");        } catch (MessagingException e) {            throw new RuntimeException(e);        }    } }

The problem is that I am getting this mail from google (google 2-step verification is  disabled):

Someone just used your password to try to sign in to your account from a non-Google app. Google blocked them, but you should check what happened. Review your account activity to make sure that no one else has access.

Is there anything I can do about it or I have to find other way to send mail?
