problem when deploy javamail service

[j.predator]

Hi
I have the next problem.

Now I use Jboss 5.1.0.GA, and cannot deploy a second javamail service when start jboss.

The file name is
custom-mail-service.xml and contains:

<?xml version="1.0" encoding="UTF-8"?>
<server>
 <mbean code="org.jboss.mail.MailService"
 name="jboss:service=CustomMail">
 <attribute name="JNDIName">java:/Custom.Mail</attribute>
 <attribute name="User">jboss</attribute>
 <attribute name="Password">123456</attribute>
 <attribute name="Configuration">
 <configuration>
 <!-- Change to your mail server prototocol -->
 <property name="mail.store.protocol" value="pop3"/>
 <property name="mail.transport.protocol" value="smtp"/>

 <!-- Change to the user who will receive mail -->
 <property name="mail.user" value="nobody"/>

 <!-- Change to the mail server -->
 <property name="mail.pop3.host" value="localhost"/>

 <!-- Change to the SMTP gateway server -->
 <property name="mail.smtp.host" value="10.0.0.51"/>
 <property name="mail.smtp.port" value="25"/>

 <!-- Change to the address mail will be from -->
 <!-- <property name="mail.from" value="jboss@localhost"/>-->

 <!-- Enable debugging output from the javamail classes -->
 <property name="mail.debug" value="true"/>
 </configuration>
 </attribute>
 <depends>jboss:service=Naming</depends>
 </mbean>
</server>

When I was trying call the service using the jndi name, jboss server always returned the default javamail configuration.

I use the next code to call my javamail service.

try {
 InitialContext initialContext = new InitialContext();
 return (Session) initialContext.lookup("java:/Custom.Mail");
 } catch (NamingException e) {
 log.error("-> Read SMTP configuration from Server FAIL ", e);
 }

This happen only when jboss start for first time, In hot deployment the problem does not happen.

Tnx for your help

Atte.
