JBAS7 ejb-jar.xml properties placeholder

[osnetwork]

Hello everyone,

I'm trying to migrate a project from JBAS6 to JBAS 7.0.2.

In my configuration I have an ejb-jar.xml file containing some placeholder values like that:

<session>

                              <ejb-name>TestOne</ejb-name>

                              <ejb-class>org.test.TestOne</ejb-class>

                              <session-type>Stateless</session-type>

                              <env-entry>

                                        <env-entry-name>ppone</env-entry-name>

                                        <env-entry-type>java.lang.Long</env-entry-type>

                                        <env-entry-value>${test.ppone}</env-entry-value>

                              </env-entry>

</session>

On JBAS6 I'm using the SystemPropertiesService to load a properties file containing the values, like that:

<mbean code="org.jboss.varia.property.SystemPropertiesService"
name="jboss:type=Service,name=SystemProperties">
<attribute name="URLList">
./conf/test.properties
</attribute>
</mbean>

Everything works smoothly and the placeholder values get replaced by the value in the properties file.

In JBAS7 I couldn't find the SystemPropertiesService, but in the Application Console we have the System Properties page where we can configure the properties values which I guess will be available globally. So I have tried to insert these values under the system properties but the values on the ejb-jar.xml doesnt get replaced.

How can I achieve the behaviout of the SystemPropertiesService on JBAS7?

Thanks in advance for help

You can add:

 
    <system-properties>
        <property name="font.files" value=""/>
    </system-properties>
                

to your standalone.xml file. If you poke around you may find a way to drag in a properties file too.

Well, the problem is not about how to add the properties file, I can add the single properties without using a separate file. The problem is that the placeholder values ${name_of_the_property} in the ejb-jar.xml file does not get replaced with the property value while the deployment is performed.

I wondered about that. Property expansion in the ejb-jar.xml file would be a non-portable extension provided in some versions of JBoss (between 5.1 and 6.0 I think).

This feature had worked for sometime in the jboss*.xml deployment descriptors, but NOT the standard deployment descriptors.

That said, it's probably about time that this functionality was formally added to the various JEE specs. It's pretty darn handy.

It must be enabled in the standalone.xml:

        <subsystem xmlns="urn:jboss:domain:ee:1.2">

            <spec-descriptor-property-replacement>true</spec-descriptor-property-replacement>

            <jboss-descriptor-property-replacement>true</jboss-descriptor-property-replacement>

            <annotation-property-replacement>true</annotation-property-replacement>

        </subsystem>
