Is there a configuration setting for JBoss 5.0 to control the order in which ear files are deployed?

Is there a mechanism either within the ear file itself (jboss-app.xml) or a configuration on the server to ensure that an EAR is loaded last and/or after another ear? For example

  1. /deploy/web-services.ear (owned by another vendor/project)
  2. /deploy/enterprise-app.ear (war, ejbs web services)

something like:

<load-precedence>
web-services.ear
enterprise-app.ear
</load-precedence>

I'm using EAR suffix configuration order in conf/bootstrap/deployers.xml. The value is ranged from 50 (started first) and 950 (started last), see LegacyDeploymentContextComparator class. In your case you would get:

<bean name="topContextComparator">
    <constructor factoryClass="org.jboss.system.deployers.LegacyDeploymentContextComparator" factoryMethod="getInstance"/>
     <property name="suffixOrder" class="java.util.Map">
        <map keyClass="java.lang.String" valueClass="java.lang.Integer">
            <entry>
                <key>web-services.ear</key>
                <value>500</value>
            </entry>
            <entry>
                <key>enterprise-app.ear</key>
                <value>600</value>
            </entry>
        </map>
    </property>
</bean>

I also use generic suffix configuration such as _<N>.ear where <N> is the starting order. This avoids changing the deployers.xml file each time I deploy a new EAR. This is useful when deploying versioned EARs such as MyEar_v20130611_3.ear (in that case N=3):

            <entry>
                <key>_1.ear</key>
                <value>500</value>
            </entry>
            <entry>
                <key>_2.ear</key>
                <value>600</value>
            </entry>
            <entry>
                <key>_3.ear</key>
                <value>700</value>
            </entry>

I've never used JBoss as an app server but looking at this documentation:

JBOSS DeploymentScanner

There is a Deployment Sorter that seems like it might be what you're looking for.

It would be handy if there was; I don't know of one. We have EAR's that depend on other EARs. Our startup code runs in a thread and re-tries on an interval until the EJB's in the other EAR are available.
