Best practice for .war? Configure and deploy or deploy and configure?

Question

In Apache Tomcat for example, I can deploy an app, stop the server, reconfigure the app in situ, then start the server again...
Is this recommended for deploying Java web apps to Oracle App Server 10g?
We currently have a consulting firm that is recommending to configure the web app before deploying. Sounds reasonable, except that they want this done via JDeveloper so that the Sys Admin can right click on the "deploy to OAS" button (ie: have the tools generate the .war file after configuration and deploy automagically).

Thanks for your feedback.
Are you aware of any way to use the *.deploy configuration file that is created by JDeveloper in an ANT script to create the .war or .ear file?
If not, I can picture the Sys Admin and developers groaning when they're told that they're JDeveloper web-app configuration cannot be used for production -- and that they must somehow duplicate that functionality in an ANT script!
I do have the below ANT scripts from Debu to do the deployment etc. But they only help after the .ear is built.
EAR file deployment:
<target name="deploy" depends="core">
<java jar="${j2ee.home}/admin.jar" fork="yes">
<arg value="${oc4j.deploy.ormi}"/>
<arg value="${oc4j.deploy.username}"/>
<arg value="${oc4j.deploy.password}"/>
<arg value="-deploy"/>
<arg value="-file"/>
<arg value="${this.build}/${this.ear}"/>
<arg value="-deploymentName"/>
<arg value="${this.application.name}"/>
</java>
</target>
Web application binding:
<target name="bind-web-app" depends="deploy">
<java jar="${j2ee.home}/admin.jar" fork="yes">
<arg value="${oc4j.deploy.ormi}"/>
<arg value="${oc4j.deploy.username}"/>
<arg value="${oc4j.deploy.password}"/>
<arg value="-bindWebApp"/>
<arg value="${this.application.name}"/>
<arg value="${this.war}"/>
<arg value="http-web-site"/>
<arg value="/${this.uri}"/>
</java>
</target>
Undeployment:
<target name="undeploy" depends="init">
<java jar="${j2ee.home}/admin.jar" fork="yes">
<arg value="${oc4j.deploy.ormi}"/>
<arg value="${oc4j.deploy.username}"/>
<arg value="${oc4j.deploy.password}"/>
<arg value="-undeploy"/>
<arg value="${this.application.name}"/>
</java>
</target>
