JNDI and java: context problem
Hi,
In my project I'd like to send an e-mail from my message-driven bean but I have 2 problem.
First of all this is my problematic code:
private void send(Context c,String to){
javax.mail.Session session = null;
try {
session = ---- see after -----
MimeMessage m = new MimeMessage(session);
m.setFrom();
m.setRecipients(javax.mail.Message.RecipientType.TO,
InternetAddress.parse(to, false));
m.setSubject("Pinestore Order confirmation");
m.setSentDate(new Date());
m.setContent("The Order has been processed",
"text/plain"); //equivalent to setText..
Store s = session.getStore();
s.connect(); // POP authentication
Transport.send(m);
System.out.println("Message sent OK.");
} catch (javax.mail.MessagingException e) {
e.printStackTrace();
} catch (javax.naming.NamingException e) {
e.printStackTrace();
}
}
public static void main(String args[]){
Context c = null;
try {
Hashtable environment = new Hashtable();
environment.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
environment.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
environment.put(Context.PROVIDER_URL, "jnp://localhost:1099");
c =new InitialContext(environment);
}
catch (NamingException ex) {
}
send(c,"xxx@domain");
}
This are my question:
this is only because I have some confusion:
Why couldn't I access to resources in jndi at java:comp/env?
If I do
Context c = b.getInitialContext();
Context compEnv = (Context) c.lookup("java:comp/env");
compEnv is null..the only things that work is c.lookup("") or lookup of everything that is located under Global JNDI Namespace..
My second question is:
If I leave the default
<attribute name="JNDIName">java:/Mail</attribute>in file mail-service.xml I can't manage to lookup via jndi to the MBean...this because the java: context seems to be invisible..only names that are in Global JNDI Namespace are visible..
So I try to get around the problem modifying the file mail-service.xml as
<attribute name="JNDIName">Mail</attribute>so now I can do in my code:
session = (javax.mail.Session)PortableRemoteObject.narrow(
c.lookup("Mail"), javax.mail.Session.class);
In this case the lookup works, but now I get still error because javax.mail.Session isn't a remote interface and then I can not do a PortableRemoteObject.narrow...
Somewhere I read that:
"objects referenced behind the java: root are not reachable by external JNDI calls, they are private to the VM of the server."
Is it true? How can I solve the problem?
Instead for the last error I don't know how to bind the result of the lookup..
Please somebody help me!!!!!
