Failed to build body from bytes

[babu79 <to...@yahoo.co.in>]

My activeMQ version is 5.2.0 which is embedded inside Jboss4.2.2.Ga. when i
am sending an object message Using Active producer inside a servlet i am
getting the following exception 
 Failed to build body from bytes. Reason: java.io.IOException: No
ClassLoaders found for: com.corpus.biemedia.servlet.MailEx 
Here is my MailEx source code

public class MailEx implements Serializable {

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	public String fromId;
	public String toId;
	public String subject;
	public String body;

	public String getFromId() {
		return fromId;
	}

	public void setFromId(String fromId) {
		this.fromId = fromId;
	}

	public String getToId() {
		return toId;
	}

	public void setToId(String toId) {
		this.toId = toId;
	}

	public String getSubject() {
		return subject;
	}

	public void setSubject(String subject) {
		this.subject = subject;
	}

	public String getBody() {
		return body;
	}

	public void setBody(String body) {
		this.body = body;
	}

}

    Here  is my MDB

public class ActiveMDB implements MessageListener {

	public void onMessage(Message arg0) {

		MailEx mail=null;
		ObjectMessage obj=null;
		
		try {

			if (arg0 instanceof ObjectMessage) {
				obj = (ObjectMessage) arg0;
				mail=(MailEx)obj.getObject();
				}
			SendMail.mail(mail);
		} catch (Exception e) {
			out.println(e.getMessage());
		}
	}
}
     
But when i am running stand alone Active Producer.I am not getting this
exception?In both the cases I used same jars.
Please provide links regarding Types of messages we  can use in jms.
Any help?thanks in advance.

I'd say you don't have the MailEx class on the same path as ActiveMQ.
I suspect it's not good enough to have it inside the webapp because
the activemq listener probably runs with only the
jboss-"system"-classpath. Did you try to put the JAR containing MailEx
inside common/lib or server/lib?
