Dynamically adding ActionMappings after startup.

[Robin Mannering <Ro...@landmarkinfo.co.uk>]

Hi all,

Wondering if anyone has tried this before...

I'd like to add a number of ActionConfig objects into the ModuleConfig after the start up of a struts app.  What I mean by this is I'd like to add ActionMappings dynamically to a struts application dependent on information available in a database.

The problem is, the ModuleConfig is frozen after struts finishes with it upon startup, so I cannot add a new ActionConfig to it in the init() method of my own startup servlet.

Does anyone have any ideas on how I can add these ActionMappings dynamically?  My current code snapshot is below:

        ModuleConfig modConfig =
            (ModuleConfig) context.getAttribute(Globals.MODULE_KEY);
        
        if (modConfig != null) {
            modConfig.getPrefix();
        }        
        
        ActionConfig actionConfig = new ActionConfig();
        actionConfig.setPath("/Test");
        actionConfig.setType("org.apache.struts.actions.ForwardAction");
        actionConfig.setParameter("/pages/myTest.vm");
        
        // note: a ForwardConfig could be added here rather than use the
        // standard org.apache.struts.actions.ForwardAction method for forwarding
        
        // add the newly constructed ActionConfig into the struts application
        LOG.debug("modConfig is configured : " + modConfig.getConfigured() );
        modConfig.addActionConfig(actionConfig);

This final line causes an IllegalStateException.

Many thanks in advance for any suggestions...

Robin
