Scheduled Task

[joshaber]

I'm trying to schedule a task to run every minute. Right now it throws this:

It doesn't look like it's finding the action.

I can run my action just fine from the GUI.

My scheduled-action-services-context.xml is:

Thanks for the help!

Looks like SimpleTemplateActionDefinition has an extra property that you need to set called parameterTemplats (see signature below).  From looking at code, the exception is thrown because it's not set.   Set it a template, and I think your NPE should go away.

  /**
     * Set the map of parameters used by the template.
     * These are processed via the template service to produce the actual poarameters.
     *
     * @param parameterTemplates
     */
    public void setParameterTemplates(Map<String, String> parameterTemplates)
    {
        this.parameterTemplates = parameterTemplates;
    }

Thanks. It looks like I'm getting the same exception though.
