UPD*
issue seemed to be behind Windows firewall and/or antivirus problem, blocking the cport connecting, cause on Ubuntu I can connect to that port with no problem. I will investigate the cause and let you know what was blocking it. Special thanks to user Perception for helping me out!

I have tried to google the issue with the similar problems
java.net.SocketException: Software caused connection abort: socket write error
But didn't get the idea how to fix mine anyway. Any tips?
Updated
if I change the port to 587 it fails to authenticate and gives me a plain text error

Your Web Service should contain the #WebService annotation. Check also the other requirements.

Here's the code snippet if anyone can help a little and look into this. The code
code compiles fine but gives an error at runtime:
package javaapplication1;
import java.sql.*;
public class Authenticate {
final String fileName = "C:/Users/darksword/Desktopdb.accdb";
Connection con = null;
Authenticate()
{
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ="+fileName;
con = DriverManager.getConnection(url,"","");
}
catch (Exception e)
{
}
finally
{
try { if(con!=null) {con.close();} } catch (Exception e) {}
}
}
void insertdata(String Name,String Address,String ContactNumber,int y) throws SQLException
{
String str = Integer.toString(y);
//Statement st=con.createStatement();
PreparedStatement pstmt = (PreparedStatement) con.prepareStatement("insert into product(id,VName,VAddress,VContactNumber) values(?,?,?,?)");
pstmt.setString(1, str);
pstmt.setString(1, Name);
pstmt.setString(1, Address);
pstmt.setString(1, ContactNumber);
pstmt.executeUpdate();
pstmt.close();
}
}
You're silently catching an exception when establishing the database connection which leaves con as null should an exception occur. Add
e.printStackTrace();
to the exception block.
In addition, you close your Connection immediately after assigning the variable in the constructor
con.close();
Here is what I have so far. I am trying to send an email in Outlook and embed that functionality into my application.
String to = "me#mine.com";
String from = "you#yours";
String host = "casarray.ex2.specificallygeneral.net";
final String username = "user#doamin.com";
final String password = "password";
Properties props = new Properties();
props.put("mail.smtp.host", host);
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.user", "user#domain.com");
props.put("mail.smtp.password", "password");
props.put("mail.smtp.port", "25");
props.put("mail.smtp.auth", "true");
Authenticator authenticator = new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
};
Session session = Session.getDefaultInstance(props, authenticator);
try {
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(from));
InternetAddress[] address = {new InternetAddress(to)};
msg.setRecipients(Message.RecipientType.TO, address);
msg.setSubject("Test");
msg.setSentDate(new Date());
msg.setText("This API works");
Transport transport = session.getTransport();
transport.connect(username, password);
transport.sendMessage(msg, msg.getRecipients(Message.RecipientType.TO));
Transport.send(msg);
transport.sendMessage(msg, address);
if (transport == null) {
JOptionPane.showMessageDialog(rootPane, "Mail carrier was shot. Sorry.");
}
}
catch (MessagingException ex) {
Logger.getLogger(AAIApplication.class.getName()).log(Level.SEVERE, null, ex);
}
And here is what I get each time:

If someone could give me a hand on this and let me know what I am doing wrong. It looks perfectly to me, so, I am assuming that the issues lies with the Exchange server. What do you think?
Thank you!
"Couldn't connect to host, port" could be caused by wrong host name, wrong port, a blocking firewall (on the server, on gateways, even on your own machine), network failure, server downtime, etc. You might want to find out if you can connect/"talk" to the mail server using telnet from the command line. See also http://www.oracle.com/technetwork/java/javamail/faq/index.html#condebug
Note: On Windows 7, you might need to install telnet first. See http://support.microsoft.com/kb/978779
I have an update method to update the content of a table based on a specific field and I am getting following exception.
Code is :
public void updateTaxoActive(String oldDesc, String description) {
Logger.getLogger(TypeCategoryJDBCTemplate.class.getName()).log(Level.INFO, "old taxonomy code is {0} new description is {1}", new Object[]{oldDesc, description});
String sql = "update product.typecategory set taxonomydescription = ? where taxonomydescription = ?";
jdbcTemplateObject.update(sql, new Object[]{description,oldDesc},new TypeCategoryMapper());
}
Exception is:
Exception in thread "AWT-EventQueue-0" org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [update product.typecategory set taxonomydescription = ? where taxonomydescription = ?]; nested exception is com.ibm.db2.jcc.am.SqlSyntaxErrorException: [jcc][1091][10824][4.13.127] Invalid data conversion: Parameter instance [Ljava.lang.Object;#1dc421 is invalid for the requested conversion.

What are you doing with TypeCategoryMapper ?
Remove ,new TypeCategoryMapper()
I want to create new thread (for Server). I have textArea where I put my logs, I created a new class status which handles it. I run new thread for object "server", I try to "deliver" my status object to server and there do status.setStatus("blabal"); But there is a problem....

BUILD SUCCESSFUL (total time: 3 seconds)
My code:
private void MainPanelButtonStartActionPerformed(java.awt.event.ActionEvent evt) {
if(!serverCreated) {
server = new Server(Integer.parseInt(MainPanelTextPort.getText()));
server.setStatusObj(status);
serverThread = new Thread(server);
//SwingUtilities.invokeLater(serverThread); don't know how to use it correctly
serverThread.start();
MainPanelButtonStart.setText("Stop");
serverCreated = true;
} else {
if(!(serverThread.isInterrupted()))
{
try {
server.getServerSocket().close();
} catch(IOException e) {}
serverThread.interrupt();
MainPanelButtonStart.setText("Start");
serverCreated = false;
}
}
}
The variable status is not instantiated on this line in the Server constructor:
status.setStatus("Server Created.");
Assuming this represents RUNNING, STOPPED, etc. these can be set internally in the Server class as it will be able to determine the run state of the server itself.
Regular Threads do not encapsulate correct interaction with the Event Dispatch Thread. SwingWorker would be a better option here. This post has an example.
Aside: Given Java code conventions, MainPanelTextPort would be represented as mainPanelTextPort.
