dynamically creating and registering an action with controller

["Scott A. Roehrig" <sa...@hotmail.com>]

I have a need to do the following...

I have an xml configuration file that will contain actions that will be
called by struts.

I want to be able to parse the file and add the mappings to the controller
during setup. I do not want the action mappings placed in the
struts-config.xml file. In addition, I also need to add an initialized
action to the controller so that it does not attempt to create the instance,
rather it uses the one I have created and registered.

It looks like this should be possible. So far I have something like the
following...

private void addMappings(Parser parser) {
    // retrieve benches-Each bench is a class that extends the Action class
    java.util.List benches = parser.getBenches();
    java.util.ListIterator iterator = benches.listIterator();
    while (iterator.hasNext()) {
        org.apache.struts.action.ActionMapping mapping = new
org.apache.struts.action.ActionMapping();
        BenchImpl benchImpl = (BenchImpl)iterator.next();
        mapping.setPath(benchImpl.getBenchUri());
        mapping.setType(benchImpl.getClass().toString());
        servlet.addMapping(mapping);
        // Workbench is a servlet that extends ActionServlet

((org.apache.cafe.workbench.Workbench)servlet).addAction(benchImpl.getBenchN
ame(), benchImpl);
    }
}

The addAction method is as follows

/**
*
* Adds action to map
* @param String
* @param org.apache.struts.action.Action
*
*/
protected void addAction(String actionName, Action action) {
    actions.put(actionName, action);
}

Seems like it should work, but the controller is still trying to initialize
a new instance of the bench when the mapping is called.

Any suggestions or clarifications?

Thanks!

Alright,

it is working. However, the put in the org.apache.struts.util.FastHashMap is
deprecated. It indicates that the commons fasthashmap will be used? Is this
change in the works?

Thanks as always:)
