How can I obtain the message resources object in a servlet?

Question

Hi everyone,

I'm developing a project with Struts and I was wondering if it's possible to get the message resources object in a servlet, which is included in the same project.

There's no possibility to get that object with the method getResources(HTTPServletRequest) because the servlet does not extends an Action class. Is there a way to do it?

Thanks in advance.

Answer 1

MessageResources-object is stored in the request scope with the key Globals.MESSAGES_KEY ("org.apache.struts.action.MESSAGE").

PropertyMessageResources p = (PropertyMessageResources) request.getAttribute(Globals.MESSAGES_KEY);
String messageValue = null;
if (p != null) {
  // Value for key errors.notempty
  messageValue = p.getMessage("errors.notempty"));
}

Well, I finally found how to do it. Just if somebody gets stuck in the same issue, here's the solution: use the java.util.ResourceBundle class in your servlet.

You just have to create the ResourceBundle passing along the name of the properties class and the locale you want to use, like you can see below:

ResourceBundle rb = new ResourceBundle("com.foo.package.theClass", myLocale);
//And then get the messages from the rb object
rb.getMessage("myPropertiesKey");

You can also do something like this:

ActionContext.getContext().getActionInvocation().getAction() //the action context is threadlocal

Once you have the action, you can use the TextProvider interface to get whatever resource you need for that action.
