Using Java EE with javamail

Using Java EE with javamail

I have a application Java EE I have in class testmail this code
public Testmail() throws MessagingException, IOException, SQLException
{
Properties props = System.getProperties();
Session session = Session.getDefaultInstance(props, null);
Store store = session.getStore("imaps");
store.connect("imap.gmail.com", "mail@gmail.com", "passsword");
//System.out.println(store);
Folder inbox = store.getFolder("Personnel");
inbox.open(Folder.READ_WRITE);
FlagTerm ft = new FlagTerm(new Flags(Flags.Flag.SEEN), false);
Message messages[] = inbox.search(ft);
for(Message message:messages)
{
//mycode
}
public static void main(String[] args) throws MessagingException,
IOException, SQLException
{
new Testmail();
}
this code is working in console.
In my servlet a have this code
//sum code
S.setAttribute("user", user);
try
{
Testmail m=new Testmail();
}

// TODO Auto-generated catch block
e.printStackTrace();
}
catch (SQLException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
