First of all, I am new to JSM.
I am trying to create a pool of connection for JMS ActiveMQ
Using the connection factory ActiveMQConnectionFactory I succeed to send/receive messages, but using the PooledConnectionFactoryBean it failed with this error:

What did I miss? I added to the classpath this jar: activemq-all-5.8.0.jar
Thanks,
kdureidy
Did you add the Spring libraries to your project?
The error
java.lang.ClassNotFoundException: org.springframework.beans.factory.FactoryBean
seems to indicate that spring-beans-X.jar is missing from your project (where X is the version of Spring that you're missing).

I am writing a Qpid client that sends a message. The example code that I am using is :
private void runTest() throws Exception {
Properties properties = new Properties();
properties.load(this.getClass().getResourceAsStream("helloworld.properties"));
Context context = new InitialContext(properties);
ConnectionFactory connectionFactory = (ConnectionFactory) context.lookup("qpidConnectionFactory");
Connection connection = connectionFactory.createConnection();
connection.start();
Session session = connection.createSession(true, Session.SESSION_TRANSACTED);
Queue queue = (Queue) context.lookup("myqueue");
MessageConsumer messageConsumer = session.createConsumer(queue);
MessageProducer messageProducer = session.createProducer(queue);
TextMessage message = session.createTextMessage("Hello world!");
messageProducer.send(message);
session.commit();
message = (TextMessage)messageConsumer.receive();
session.commit();
System.out.println(message.getText());
connection.close();
context.close();
}
The accompanying config is :
java.naming.factory.initial = org.apache.qpid.jndi.PropertiesFileInitialContextFactory
connectionfactory.qpidConnectionFactory = amqp://guest:guest#clientid/?brokerlist='tcp://localhost:61111'
queue.myqueue = queue1
The ERROR that I am getting is :

Looks like it is unable to initialize the context for the Properties file.
I have an ActiveMQ instance running locally on port 61111. The Properties file is indeed in my CLASSPATH. What else could I be missing here ?
Try java.naming.factory.initial = org.apache.qpid.jms.jndi.JmsInitialContextFactory
I tried using the rabbitMQ and while creating the connection I got the below given exception with output, I am not sure what went wrong.
The factory is working fine and the hostname,port , username and password are setting correctly, but the connection is failing each time.
In main
parametres setted , now creating the connection
The host name and other params are localhost
The host name and other params are admin
The host name and other params are admin
The host name and other params are 5672
setted all the params

I just found the solution to this .
I added the common-io-2.5.jar file in the project and after re-building it ,it worked.
The jar was obtained from the link : http://commons.apache.org/proper/commons-io/download_io.cgi
I would like to save data from each partition to MySQL Database. For doing that I created Class which implements VoidFunction<> :
public class DatabaseSaveFunction implements VoidFunction<Iterator<String>> {
/**
*
*/
private static final long serialVersionUID = -7039277486852158360L;
public void call(Iterator<String> it) {
Connection connect = null;
PreparedStatement preparedStatement = null;
try {
Class.forName("com.mysql.jdbc.Driver");
connect = DriverManager.getConnection("jdbc:mysql://"
+ "xxx.us-west-2.rds.amazonaws.com" + "/"
+ "xxx", "xxx", "xxx");
preparedStatement = connect
.prepareStatement("insert into testdatabase.test values (default, ?)");
while (it.hasNext()) {
String outputElement = it.next();
preparedStatement.setString(1, "" + outputElement.length());
preparedStatement.executeUpdate();
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
} finally {
try {
connect.close();
preparedStatement.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
}
And in my main method class I'm calling:
output.foreachPartition(new DatabaseSaveFunction());
I'm getting following error:
15/05/06 15:34:00 WARN scheduler.TaskSetManager: Lost task 0.0 in stage 1.0 (TID 4, ip-172-31-36-44.us-west-2.compute.internal): java.lang.ClassNotFoundException: DatabaseSaveFunction

Can anybody tell me what I'm doing wrong ? I would be very grateful for that.
Export the external class to jar and add that like sc.addJar("/path/x.jar") where sc is JavaSparkContext in your main. Then you wont get this error. The error is because you spark program is not able to find the class. Moreover in spark 1.3 and greater you can simple use a map options of jdbc and then use load("jdbc", options) to create a data frame and load data from any RDBMS. its really handy. I am not sure if this method works for connecting any RDBMS into spark. Please tell me if you have any other question.
I'm working on a tow projects , EJB project (where i have all my EJB Remote) and the other project is a simple java application with main method. but when i try to lookup an EJB statless and remote via JNDI , it doesn't work.
Really i used many way but no good results.
this is the code and the consol error .
1) My Ejb project when i clean and install it , it gives me a jar file.
2) I use Jboss EAP6.
3) i have a jndi.properties insid of src/main/ressouces where i have this :

} catch (NamingException e) {

when i run my main application , it gives me that :

Those properties are used for connecting to an older jboss version.. For eap 6, you have to use remoting instead of jnp.
Here´s a tutorial that will show you how to connect
