Sending Files using Active MQ with BlobMessage

问题

I have an requirement in my application to send files from one application to another over HTTP/FTP protocol. I found following link which tells that the same can be done using Active MQ with supoort of Blob messages:

activemq.apache.org/blob-messages.html

I configured ActiveMq 5.8 on my windows machine, included required dependency for ActiveMQ lib in my pom.xml and i am able to send the simple javax.jms.TextMessage and javax.jms.MapMessage with org.springframework.jms.core.JmsTemplate

But while i moved to send BlobMessage using following method, a compile time error arises while creating the BlobMessage object from javax.jms.Session object which says

The method createBlobMessage(File) is undefined for the type Session

Here is the method i am using:

public void sendFile(){


        jmsTemplate.send(
        new MessageCreator() {
          public Message createMessage(Session session) throws JMSException {


              BlobMessage message = session.createBlobMessage(new File("/foo/bar"));
              return jmsTemplate.send(message);
          }
        }


);
}

Please help to resolve this compile time error.

Regards,

Arun

回答1:

The BlobMessage methods are not JMS spec methods so they won't appear in the javax.jms.Session interface, you need to cast to org.apache.activemq.ActiveMQSession in order to use the BlobMessage specific functionality.
