Simple Service Parameterization

[bwallis42]

As part of my application I am deploying a mailservice using the org.jboss.mail.MailService mbean. In the service file I need to specify various parameters such as the mail host, login details, etc.

Currently we do that at installation time by massaging the mail-serivce.xml file, replacing some tokens with the correct values. Of course this means I cannot include this service.xml file in my ear file as part of the application.

Is there anyway I can do this so that I can just use a parameter file somewhere (maybe a properties file or as system properties at jboss startup). ie: my service file would be something like:

<mbean code="org.jboss.mail.MailService"
 name="jboss:service=ESERV_Mail">
 <attribute name="JNDIName">java:/ESERV_Mail</attribute>
 <attribute name="User">${mail.user}</attribute>
 <attribute name="Password">${mail.passwd}</attribute>
etc...

There are many other cases where I would like to be able to do something like this such as database connection parameters (user/pass@sid), database server hostname, JCA parameters for external host names, ports, etc.. Is there a general mechanism for doing this?

thanks,

We have supported such system property ref syntance for a long time. See the following for the current syntax:

Thanks Scott for pointing me to that page.

I'm running a 3.2.3 jboss installation so i expect that only the system property references are going to work for me. Do these work in 3.2.3?

thanks

Yes, but only the simple ${x} syntax is supported in that version. Such references are supported in -service.xml and -ds.xml in that version, but not anywhere else. Latter version support such references in many other jboss descriptors.
