Answer 1

You can implement a ServletContextListener to respond to the servlet starting up.
Create your implementation like so:
public class SimpleInitializer implements ServletContextListener {
#Override
public void contextInitialized(ServletContextEvent sce) {
//Place your startup logic here.
}
#Override
public void contextDestroyed(ServletContextEvent sce) {
}
}
Then, include it in the web.xml, like so:
<listener>
<display-name>SIMPLE Startup Listener</display-name>
<listener-class>com.you.init.SimpleInitializer</listener-class>
</listener>

Answer 2

MBeanServerConnection server = (MBeanServerConnection)new InitialContext().lookup("jmx/rmi/RMIAdaptor");
ObjectName on = new ObjectName("jboss.system:type=Server");
Object var = server.getAttribute(on, "Started");
System.out.println(**var**);
One more thing you can do is run a thread and check the value of var in Filter Dispatcher. If it is true then call the web service and set the data into your Servlet Context, otherwise sleep the thread for a particular amount of time. Once the value you have retrieved Stop this thread.

try{
MBeanServerConnection server = (MBeanServerConnection)new InitialContext().lookup("jmx/rmi/RMIAdaptor");
ObjectName on = new ObjectName("jboss.system:type=Server");
Object var = server.getAttribute(on, "Started");
System.out.println(var);
String serverURL = "http://gaurav-compaq-presario-c700-notebook-pc:8080/WServer?wsdl";
String message = "gaurav";
HashMap env = new HashMap();
String[] creds = new String[1];
creds[0] = message;
env.put(JMXConnector.CREDENTIALS, creds);
JMXServiceURL url = new JMXServiceURL(serverURL);
JMXConnector jmxc = JMXConnectorFactory.connect(url, env);
// Remember to call jmxc.close() when you are done with server connection.
MBeanServerConnection server1 = jmxc.getMBeanServerConnection();
System.out.println(server.getAttribute(new ObjectName("MyDomain:key=property"), "AnAttribute"));
server.invoke(new ObjectName("MyDomain:key=property"), "doSomething", new Object[0], new String[0]);
}catch(Exception e){
System.out.println(e);
}
