AS7 Configuration/ CLI - How best to represent an array attribute

j4m3s Jul 9, 2012 4:45 PM

I have a custom LoginModule which accepts an array (of Strings) as one of its module-options, but am not sure on the best way to store this array in the configuration (using the CLI). I've found three ways and none is ideal:

* I've found that i can add multiple module-option name/value pairs with the same name - but only the last one to be added is passed through to the LoginModule's initialize method.

* I can also add what looks like an array through the jboss_cli, but it's actually stored as a single String with the quote marks translated to @ quot; and the comma in the middle of the string.

* I've fallen-back to passing-in all of the parameters concatenated together, delimited by pipes. However, the array values can each be quite long, and it's not possible to view/ edit the string through the web interface, only replace the whole thing.

* I guess I could go with a list of module-options with numbered names, and pull all of them from the map and build the array that way, but it's likely to be error-prone when users miss a number in the sequence etc.

Is there a better way to pass/ store an array of attributes in the jboss config?

Thank you

Hi,

there are many ways if you are refering to DMR model. it can be list of strings or map<String,String>
but to better help you can you provide bit more context as atm i cannot tell what exacly are you trying to do and where.

Thanks for the quick reply. I'm not sure what DMR model is I'm afraid.

I thought the question might be generic to any attribute, but in my case specifically, the attribute can be queried using the following command in the CLI:

/subsystem=security/security-domain=my-auth/authentication=classic/:read-attribute(name=login-modules,include-defaults=true)

This command returns the following:
{
    "outcome" => "success",
    "result" => [{
        "code" => "com.me.MyLoginModule",
        "flag" => "required",
        "module-options" => [
            ("cookie-names" => "Cookie1|Cookie2"),
            ("session-type" => "EITHER")
        ]
    }]
}

And I would like to be able to set "cookie-names" to be an array (or List!) of Strings, rather than a pipe-delimited String.

The LoginModule extends org.jboss.security.auth.spi.AbstractServerLoginModule. The method initialize has a parameter Map<String,?> options that is set by JBoss based on the contents of the module-options part of the JBoss config file. I would like to know how to set the module-options in the config file so that I can retrieve one from the Map as a List<?> or array please.

Hope that's clearer - happy to provide more info if not
