i have 3rd party smpp connection.
so i created java smpp client and its working fine.
how i can create smpp server connect to 3rd party smpp connection and need to send sms via that created smpp server. my problem is i doesn't know how to connect smpp server to smsc/smpp 3rd party connection
please help to me connect this smpp server to smpp 3rd party server for send sms..

I have this class, that returns an object, if the email, password and category (enum) are correct:
public class LoginManager {
private static LoginManager instance = new LoginManager();
private LoginManager() {
super();
}
public static LoginManager getInstance() {
return instance;
}
public ClientFacade login(String email, String password, ClientType clientType) throws SQLException {
if (clientType == ClientType.Administrator) {
AdminFacade adminFacade = new AdminFacade();
if (adminFacade.login(email, password) == true) {
return adminFacade;
} else {
return null;
}
} else if (clientType == ClientType.Company) {
CompanyFacade companyFacade = new CompanyFacade();
if (companyFacade.login(email, password) == true) {
return companyFacade;
} else {
return null;
}
} else if (clientType == ClientType.Customer) {
CustomerFacade customerFacade = new CustomerFacade();
if (customerFacade.login(email, password) == true) {
return customerFacade;
} else {
return null;
}
} else {
return null;
}
}
}
How do I use that object in another class?
This is the other class, that is supposed to use the object that return:
public class Test {
CouponsDBDAO coupDBD = new CouponsDBDAO();
CouponExpirationDailyJob dailyJob =
new CouponExpirationDailyJob(coupDBD, false);
LoginManager Log = LoginManager.getInstance();

try {
Log.login("admin#admin.com", "admin", ClientType.Administrator); {
}
} catch (SQLException e) {
System.out.println(e.getMessage());
}
}
}
How do I use now the adminFacade for example?
try
LoginManager Log = new LoginManager();
public void testAll() {
try {
ClientFacade facade = Log.login("admin#admin.com", "admin", ClientType.Administrator);
facade.DoSomethingUseful();
} catch (SQLException e) {

I have a topology in which I am trying to count word occurrences which are being generated by SimulatorSpout (not real Stream) and after that write to MySQL database table, the table scheme is very simple:
Field | Type | ...
ID | int(11) | Auto_icr
word | varchar(50) |
count | int(11) |
But I am facing weird problem(as I beforementioned)
I successfully submitted The Topology to my Storm Cluster which consists of 4 supervisors, and I can see the flow of the Topology in Storm Web UI
(no exceptions) but when I checked the MySQL table, to my surprise, the table is empty...
ANY COMMENTS, SUGGESTIONS ARE WELCOME...

}
It is because the _collector.ack(tuple) is not being called when there is exception thrown. When there are too many pending tuple, spout will stop sending new tuples. Try throwing out RuntimeException instead of printStackTrace.
