This exception appears when i push "Connect" button for ports : 11201 (client-vendor connection) and 11202 (vendor-broker connection).
The database is created by WampServer application..
Re: Exception (payword protocol)
Without code posted we all have to rely on guesses. Here's my guess: you are accessing an ArrayList for index -1, which will throw an exception. Based upon the stack trace, I'd guess you are trying to get the selected row or column within a table - but there are none selected so the returned selected row is -1 (JTable (Java 2 Platform SE 5.0)). Again beyond that its anyone's guess...

Client to Vendor Connection

/**

}
public void connect(){

}

}
Vendor to Client connection
Code :
package payword.vendor;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.ServerSocket;
import java.net.Socket;

public void startListening(){

socket.close();
} catch (Exception ex) {

}
}
});
thread.start();
}
public void disconnect(){
try {
serverSocket.close();
} catch (IOException ex) {
parent.log("ERROR: Could not disconnect.");
}
}
}
And this is the Certificate Table Model .. that comes the error
Code :
package payword.user;
import payword.User;
import java.util.ArrayList;
import java.util.List;
import javax.swing.table.AbstractTableModel;
import payword.ClientCertificate;
/**
*
* @author Thodoris
*/
public class CertificateTableModel extends AbstractTableModel {
int lines = 0;
List<ClientCertificate> contents = new ArrayList<ClientCertificate>();
public void refreshTable(User user){
ClientDbConnection connection = new ClientDbConnection();
contents = connection.getCertificateList(user);
lines = contents.size();
fireTableDataChanged();
connection.close();
}
public int getRowCount() {
return lines;
}
public int getColumnCount() {
return 3;
}
public Object getValueAt(int rowIndex, int columnIndex) {
ClientCertificate cert = contents.get(rowIndex);
if(columnIndex == 0){
return cert.getUserName();
}else if(columnIndex == 1){
return cert.getExpirationDate();
}else{
return cert.getAmmount();
}
}
@Override
public String getColumnName(int column){
if(column == 0){
return "Broker";
}else if(column==1){
return "Expires";
}else{
return "Ammount";
}
}
public ClientCertificate getSelected(int i){
return contents.get(i);
}
}
Re: Exception (payword protocol)
The exception is being thrown in the ClientWindow vendorConnectButtonActionPerformed() method, please post that code.
Re: Exception (payword protocol)
here you are..
Code :
private void vendorConnectButtonActionPerformed(java.awt.event.ActionEvent evt) {
int port = Integer.parseInt(portTf1.getText());
int amount = (Integer)amountSpinner.getValue();
int i = certificateTable.getSelectedRow();
CertificateTableModel model = (CertificateTableModel)certificateTable.getModel();
ClientCommitment commitment = new ClientCommitment(model.getSelected(i), new Date(), "", amount);
vendorConnection = new ClientToVendorConnection(addressTf1.getText(), port, this, commitment, user);
Re: Exception (payword protocol)
And here I thought you may have actually taken my first suggestion...Read the API for getSelectedRow() JTable (Java 2 Platform SE 5.0)
Code :
int i = certificateTable.getSelectedRow();
i will be -1 if there are no rows selected, and you cannot access an ArrayList index at -1 in the following line of code
Code :
model.getSelected(-1) ///will throw an exception
Fix is to make sure i is within the bounds of your list
Re: Exception (payword protocol)
ill give it a try
tnx for your help copeg!
