Session bean for sending e-mail

[Erwin DES]

Hi,
I use a method in my session bean that contains following code-fragment :

// Get properties object
Properties props = System.getProperties();
       
// Define SMTP host property
props.put("mail.smtp.host",smtpHost);
         
try {
     // Get a session
     Session session =  Session.getDefaultInstance(props,null);
         
// Create a new message object
MimeMessage message = new MimeMessage(session);

The problem is that I get an error in Runtime :
" java.rmi.RemoteException: nested exception is: java.security.AccessControlException: access denied (java.util.PropertyPermission * read,write); nested exception is:
java.security.AccessControlException: access denied (java.util.PropertyPermission * read,write)...."
How exactly can I solve this problem?
Thanks for any help.

In Java Network Programming by E R Harold published by Orielly he does -
props = new props();
props.put ( "mail.host", "mail.cloud9.net" );
I see you have a different key. Where did you get it?
Over here they talk about a mail.debug property. Have your tried that?

[Erwin DES]

Thanks for your response.
The example I use is partly taken from the book "Teach yourself J2ee in 21 days" from SAMS.
The program works fine if used outside an EJB (thus a simple main class for example).
Thanks to your reference to Sun FAQ, I think the problem has to do with granting access to the Property (because I use System.getProperties();.
I followed the instruction in the FAQ by inserting a grant clause to the security policy file... but is still doesn't work.
I also inserted session.setDebug(true) to my code to obtain more error-results...but I still don't get more information. I think the errorlist I get is all there is.
Hereby the complete list.

What other solution can I use?
Thanks for any help!

Over here they do it from in a bean the difference being they get their session from the JNDI context.
Whose EJB container are you using?

[Erwin DES]

I have already tried out the example from Sun. But the problem is that I use Sun One EE (free download / 60 days trial) and that the example uses the deploytool.
The question remains then how to define my mail-session in the JNDI?
Sun One uses the J2ee RI.

[Dana Hanna]

Why use System.getProperties()?
These would be defining properties for the entire JVM, which is why your ejb container is complaining. You aren't playing nice with other EJBs!
Use:
Properties props = new Properties();

[Erwin DES]

Thanks,
My code is working now.
But, I'm still interested in how to make a better solution in working it out with JNDI.
The problem is that I don't find the right settings for Sun One EE.
Any suggestions?
Thanks,
EDS

[Dana Hanna]

What setting are you looking for?

[Erwin DES]

I need access to the JNDI-Tree and I need to define my mail-session in the JNDI. This way I don't have to hard-code my servername and e-mailaddress ...
Problem is I don't now how with Sun One EE.
