You can not use @EJB annotation outside of EJB container, it will work only inside container in deplorable classes (Like Other EJB class , Servlet if deployed in same container)

If you want to call EJB from outside container , you need to lookup EJB, Try below code

public class Main { public static void main(String[] args) { Hashtable<String, String> env = new Hashtable<String, String>(); env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory"); env.put(Context.SECURITY_PRINCIPAL, "USERNAME"); env.put(Context.SECURITY_CREDENTIALS, "PASSWORD"); env.put(Context.PROVIDER_URL, "t3://localhost:7001"); InitialContext ic = new InitialContext(env); HelloWorldRemote api = (HelloWorldRemote) context.lookup("HelloWorld#com.HelloWorldRemote");; System.out.println("<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>"); System.out.println(api.hello()); } }

A simple code to connect with JMS server and send message, may be this will help you.

Properties env = new Properties(); env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming rg.jnp.interfaces"); env.put(Context.PROVIDER_URL, "localhost:1099"); Context remoteCtx = new InitialContext(env); Queue queue = (Queue)remoteCtx.lookup("queue/testQueue"); QueueConnectionFactory queueFactory =(QueueConnectionFactory)remoteCtx.lookup("ConnectionFactory"); queueConnection = queueFactory.createQueueConnection(); QueueSession queueSession = queueConnection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE); QueueSender queueSender = queueSession.createSender(queue); TextMessage message = queueSession.createTextMessage(); message.setText(Long.toString(2));
queueSender.send(message);

Don't go for EJB 2.0.

Hibernate 3.* and EJB 3.0 is best choice for Java ORM tool. Acctually Java EJB 3.0 is A Hibernate Clone

May be you are using different version client.jar in the Client end. take the jboss-client jar from the JBOSS_HOME/client/ and put it in your client's class path.

Also Instead of localhost use IP address

Go to message properties.

Select ActionKind > Return

(See attachment image)

Chain of Responsibility will be good for this scenario.

Why you are worrying about Thread management , your code is in a servlet and , servlet is deployed in a servlet container , and all Thread management is servlet container task.

You only concentrate on your business logic and left all Thread management or request handling to servlet container

This might help you

I have a problem with logger in my application. I have implemented Java. Api java.util.logging. for logging . I set my log level to INFO and logfile appender everything is working fine.

There is one scheduler which run every night , after running that scheduler the log lever automatically switch to FINE or sometime FINER. Because of that its generation lots of unnecessary FINE or FINERlog files.

I debug a lot but didn’t get any solution, can anyone please suggest me any way to solve this problem?

Below is a sample of log file where log level is getting change form INFO to FINER.

You can do it using JSTL also.

Go through below code , it will help you.

<% <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <script language="JavaScript"> function setInitialState() { var arr = new array(); var i = 0; <c:forEach items="${CustomFieldDetails}" var="current" varStatus="status"> arr[i] = '<c:out value='${current.shortName}'/>'; i++; </c:forEach> } </script>

In above code CustomFieldDetails is a String of objects which is set in request object.

Go through below code , it will help you.

<% int i[]; i=new int[2]; i[0]=1; i[1]=2; %> <html> <head> <script language="JavaScript"> var jsArr = new Array(); <% for (int j=0; j < i.length; j++) { %> jsArr[<%= j %>] = <%=i[j] %>; <%}%> </script>
