Hi, Dark Cloud
Wish You Happy New Year
&
Sorry for late replying your thanks, actually I am busy in my engineering exam.
I have tried the singleton pattern given by you, but still i am
getting some problems and errors.
======================================================================
MyServiceWrapper.java file looks like:
======================================================================
package misc;
import java.io.IOException;
import org.smslib.GatewayException;
import org.smslib.SMSLibException;
import org.smslib.Service;
import org.smslib.TimeoutException;
import org.smslib.AGateway.Protocols;
import org.smslib.modem.SerialModemGateway;
public class MyServiceWrapper
{
private Service service;
private static MyServiceWrapper instance;
@SuppressWarnings("unchecked")
private MyServiceWrapper() throws TimeoutException,
GatewayException, SMSLibException, IOException, InterruptedException
{
super();
Service service = new Service();
SerialModemGateway gateway = new
SerialModemGateway("modem.com1",
"COM23", 57600, "Samsung", "Guru E1410");
//SerialModemGateway gateway = new
SerialModemGateway("modem.com1",
"COM9", 57600, "Nokia", "3220");
gateway.setProtocol(Protocols.PDU);
gateway.setInbound(true);
gateway.setOutbound(true);
gateway.setSimPin("0000");
service.addGateway(gateway);
service.startService();
System.out.println("SMSLib Gateway ID: "+gateway.toString());
Enum e=service.getServiceStatus();
System.out.println("SMSLib Service Status: "+e.toString());
}
public Service getService()
{
System.out.println("Service ID : "+this.service);
return this.service;
}
public static MyServiceWrapper getInstance() throws Exception
{
if (instance == null) {
synchronized(MyServiceWrapper.class){
instance = new MyServiceWrapper();
System.out.print("Instance : "+instance);
System.out.println();
}
}
else
{
System.out.println();
System.out.print("Instance : "+instance);
}
return instance;
}
public static void main(String args[]) throws Exception
{
MyServiceWrapper sw = MyServiceWrapper.getInstance();
Service service = sw.getService();
System.out.println("Service Wrapper : "+sw);
System.out.println("Service ID : "+service);
}
}
======================================================================
======================================================================
SendMessage.jsp file looks like:
======================================================================
<%...@page
language="java"
contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"
import="misc.MyServiceWrapper,
org.smslib.OutboundMessage,
org.smslib.Service"
%>
<%
MyServiceWrapper sw1 = MyServiceWrapper.getInstance();
Service service = sw1.getService();
OutboundMessage msg = new OutboundMessage("12345", "HELP");
try{
service.sendMessage(msg);
}
catch(Exception e)
{
out.print(e.getMessage()) ;
}
out.print(msg);
%>
======================================================================
Now when i run MyServiceWrapper.java file explicitely
the getService() method is returning null and the console is
displaying the following output:
======================================================================
og4j:WARN No appenders could be found for logger (smslib).
log4j:WARN Please initialize the log4j system properly.
SMSLib Gateway ID: org.smslib.modem.serialmodemgate...@1d0c1d0c
SMSLib Service Status: STARTED
Instance : misc.myservicewrap...@4d574d57
Service ID : null
Service Wrapper : misc.myservicewrap...@4d574d57
Service ID : null
======================================================================
as the service is started an instance of wrapper is created but ,
Because of these error i am getting NullPointerException and
NoSuchPortException while publishing SendMessage.jsp file on the
server
I am using IBM WebSphere Application Server 7.0 and Rational
Application Developer tool on Windows 7.
Please help me...
