Most application configuration changes would result in config.ser  
changes.  For instance adding or removing an ejb would add or remove a  
gbean from the configuration.  Changing something in web.xml or ejb- 
jar.xml or the geronimo or openejb plans would result in a change.   
Changing the code inside one of your components (servlet, ejb) without  
changing the ejb interface should not result in a change.

I definitely would not advise trying to work around the deployment

You still might be able to script deploying/undeploying your  
application using the geronimo-maven-plugin if you are OK with use of
