System Property reference does NOT work in ""?

[ybxiang.china]

Dear all,

    I defined my System properties:

<?xml version='1.0' encoding='UTF-8'?>

<server xmlns="urn:jboss:domain:1.2">

    <extensions>
        ...
    </extensions>

    <system-properties>
        <property name="nms.system.property.datasource.jndi-name" value="java:jboss/datasources/NmsMySqlDS"/>
        <property name="nms.system.property.datasource.connection-url" value="jdbc:mysql://localhost:3306/nms"/>
        ...
    </system-properties>

and datasource

	<datasource jndi-name="java:jboss/datasources/NmsMySqlDS" pool-name="MySqlDS">
	<connection-url>${nms.system.property.datasource.connection-url}</connection-url>
	<driver>com.mysql</driver>
	...
	</datasource>

Now, everything works well

But after I changed datasource definition to

	<datasource jndi-name="${nms.system.property.datasource.jndi-name}" pool-name="MySqlDS">
	<connection-url>${nms.system.property.datasource.connection-url}</connection-url>
	<driver>com.mysql</driver>
	...
	</datasource>

I got bellow exception

10:07:18,015 ERROR [org.jboss.as.server.deployment.scanner] (DeploymentScanner-threads - 1) {"JBAS014653: Composite oper
ation failed and was rolled back. Steps that failed:" => {"Operation step-2" => {"JBAS014771: Services with missing/unav
ailable dependencies" => ["jboss.persistenceunit.\"nms-server-ear.ear/nms-server-ejb.jar#nms-server\"jboss.naming.contex
t.java.jboss.datasources.NmsMySqlDSMissing[jboss.persistenceunit.\"nms-server-ear.ear/nms-server-ejb.jar#nms-server\"jbo
ss.naming.context.java.jboss.datasources.NmsMySqlDS]"]}}}

Obviosly, the datasource jndi name is NOT translated!!!

I found that <login-module> has the same issue:

	<login-module code="org.jboss.security.auth.spi.DatabaseServerLoginModule" flag="required">
	<module-option name="password-stacking" value="useFirstPass"/>
	<module-option name="dsJndiName" value="java:jboss/datasources/NmsMySqlDS"/>
	<module-option name="principalsQuery" value="SELECT passwdHash FROM testuser WHERE name=?"/>
	<module-option name="rolesQuery" value="SELECT r.name, 'Roles' FROM testroles r, testuser u where u.id=r.user_id and u.name=?"/>
	<module-option name="hashAlgorithm" value="SHA-256"/>
	<module-option name="hashEncoding" value="Base64"/>
	<module-option name="hashCharset" value="UTF-8"/>
	<module-option name="unauthenticatedIdentity" value="guest"/>
	</login-module>

Namely, I can NOT change

<module-option name="dsJndiName" value="java:jboss/datasources/NmsMySqlDS"/>

to

<module-option name="dsJndiName" value="${nms.system.property.datasource.jndi-name}"/>

Is my configuration wrong?

I read other system property reference:

	<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
	<socket-binding name="management-native" interface="management" port="${jboss.management.native.port:9999}"/>
	<socket-binding name="management-http" interface="management" port="${jboss.management.http.port:9990}"/>
	<socket-binding name="management-https" interface="management" port="${jboss.management.https.port:9443}"/>

Then, does this mean, ONLY jndi-name and <login-module> do NOT support such usage?

Hi Xiang,

it depends on the subsystem which attributes are allowed to have such expressions.

You might get more information via CLI with the :read-resource-description operation.

Dear Fink,

       Thanks.

       I will NOT use system property reference. I dislike to remeber so many tiny things.

Now, I have configured datasource, SSL, and JAAS successfully with JBoss AS 7.

I love it!
