Hi,

ReservationAction.java:73

There is your error, so look why there is a NPE on that line and if you need some more help, send the whole bean, so we can have a look.

Hi sir ,
        Thanx for ur reply.Am sorry i cant send u the whole bean . but i can send u the piece of code where i am facing null pointer.

public void confirmInvitationMail(){
         Contexts.getEventContext().set("invitation", invitation);
           try {  
                 if(renderer == null){
                  renderer = Renderer.instance();   
                 }
                
   null pointer >>  renderer.render("/basic/invitationMail.xhtml");
                } catch (Exception ex) {
                 ex.printStackTrace();
                }
    }

Hi,

This won't help much, but I can suggest some things:

• The renderer is not null because it is called,


• The mail connection can't be created because it isn't correctly configured (hence the com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:557) error.


• If you are using JBoss , you must have a Datasource in your deploy dir (XXX-ds-xml)


• You must have a reference to the mail ds in your components.xml


• Try to connect yourself to the mailserver (with a simple JavaMail program) and check if you can send something.
