Struts 1: Access MessageResources from doStartTag in TagSupport

I am trying to pull in my Struts (1.3) ApplicationResources.properties file (based on the locale of the request) inside the doStartTag method of a Java Tag. I am using the following code :

HttpServletRequest request = (HttpServletRequest)pageContext.getRequest();
MessageResources resources = (MessageResources) request.getAttribute(Globals.MESSAGES_KEY);

System.out.println(resources.getMessage(request.getLocale(),"global.state.label");

However, it is throwing a NullPointerException (resources is NULL).

Is there a better way to do this? This is the same code used in the Action.getResources(request) method but it doesn't seem to be working in the context of the tag.

I figured it out, here's the solution in case anyone else needs it:

HttpServletRequest request = (HttpServletRequest) pageContext.getRequest();
MessageResources messages = MessageResources.getMessageResources("com.mycompany.struts.ApplicationResources");
messages.getMessage(request.getLocale(),"global.choose.label");

The string passed into the getMessageResources(String) method should be the parameter attribute of the <message-resources> tag in your struts-config.xml.
 
I agree. Here's the link: http://aspose.com/file-tools
