I think a worthwhile enhancement would be the ability to enable/disable the verify action behavior in struts.properties/struts.xml. Please file a JIRA ticket. Thanks,

Martin, Wouldn't your suggestion ensure that all the action beans and their dependencies (like database connections) get instantiated when the application gets loaded? This is the situation that I am seeking to avoid. If the dependencies are set up right, Spring will make sure that the datasource is instantiated before any other object that depends on it directly or indirectly. I did a crude little experiment. I replaced the implementation of the method verifyAction() in the class XmlConfigurationProvider in the xwork-2.0.1.jar to always return true. This is the method that checks the action classes to verify that the no-arg constructor is available and public. I am now getting the effect that I was looking for. Not very satisfying, but unless there is some other option out there, it will have to do until the code base is updated.
