Cannot convert DataHandler to JMS mesage

[Praveen Kumar Jayaram]

Hi

I am using ActiveMQ for messaging and Mule 2.0.2 as ESB.
As a normal flow if I transfer a string it will access web service and place the string in messaging queue. Mule will read the string automatically and transfers the data further for processing.

If I pass a DataHandler object (to transfer a file) using web service. It says "Cannot convert object [javax.activation.DataHandler@8edd79] to JMS message", even though I am converting it to JMS message.

Here is the web service method which does the conversion,

    
public void postFile(DataHandler dh)
{
try{
SimpleMessageConverter converter = new SimpleMessageConverter();
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");
Connection connection = connectionFactory.createConnection();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
javax.jms.Message jmsMsg = converter.toMessage(dh, session);
queueSender.sendMessage(jmsMsg);
}
catch(Exception ex)
{
System.out.println("Error in postFile: " + ex.getMessage());
}

queueSender.sendMessage(jmsMsg); will be mapped to the following method

    
public void sendMessage(javax.jms.Message msg)
{
try{
jmsTemplate.convertAndSend(msg);
}
catch(Exception ex){
System.out.println("Error at sendMessage: " + ex.getMessage());
}
}

And sometimes I get the following error message.
