Java.io.IOException: Transport scheme NOT recognized: [tcp]

Question

Hi everyone, I developed a Java class that allow me to connect, create, send and receive information to an ActiveMQ queues.
However when I loaded this java class to Oracle 11gR2 (11.2), the java class did not show any error message (its status is active and without errors. The output I got in SqlDeveloper is
*java.io.IOException: Transport scheme NOT recognized: [tcp].* When I called this Java Class from Jdeveloper 11g It worked but PL/SQL did not.
This is the Java Class I have been using
import javax.jms.JMSException;
import javax.jms.*;
import javax.naming.Context;
import javax.naming.InitialContext;

// Receiving
messageID = outMessage.getJMSMessageID();
String selector = "JMSCorrelationID = '"+messageID+"'";
System.out.println("JMSCorrelationID = '"+messageID+"'");
queueReceiver = session.createReceiver(destResp, selector);
System.out.println("Receiving Message.");
Message inMessage = queueReceiver.receive(2000);
if ( inMessage instanceof TextMessage ) { 
replyString = ((TextMessage) inMessage).getText();
System.out.println("Message Received: " + replyString + "'");
else
replyString = "Error: TextMessage is empty";
} catch (JMSException jmse) {
//System.out.println("Error:JMS Exception occurred: " + jmse.toString());
return "Error:JMS Exception occurred Receiving: " + jmse.toString();
} catch (Exception e) {
//System.out.println("JNDI API lookup failed: " + e.toString());
//e.printStackTrace();
return "Error:JNDI API lookup failed Receiving: " + e.toString();
} finally {
queueReceiver.close();
queueSender.close();
session.close();
connection.close();
return replyString;
This is th pl/sql wrapper
create or replace
function ActiveMQRequest( url in varchar2,
destNameReq in varchar2,
destNameResp in varchar2,
OperationType in varchar2,
XMLmessage in varchar2) return varchar2
as language java
name 'ActiveMQRequest.Request( java.lang.String,java.lang.String, java.lang.String , java.lang.String , java.lang.String ) return java.lang.String';
and this is the JDeveloper Output
Sending message.:

When I run in Oracle Sqldeveloper the output was
Error:JMS Exception occurred Create Queue Connection: javax.jms.JMSException: Could not create Transport. Reason: java.io.IOException: Transport scheme NOT recognized: [tcp]
Do you know what do I do in the Oracle 11gR2 configuration for making this work. I would appreciate your help.
Thanks

Perhaps you did not notice that you posted to a forum named "Database - General" with a question that is neither general nor related to the Oracle Database.
Please update this thread (use Edit) and change the subject to "Please Ignore."
Then repost your question in a Java related forum.
Thank you.
