How can I catch a spring message JstTagException?

I'm using Spring MVC 3.0 with sitemesh and spring message bundles. For example, I have the following:

<spring:message code="nav.item.name"/>

If nav.item.name does not exist in my resource file, I receive a blank page and a JspTagException in the console, which I can't catch with my @ExceptionHandler method. I'm assuming I can't catch it because the error is part of the view rendering. I've also tried to create a custom HandlerInterceptorAdapter, and modify the web.xml both with no success. Interestingly enough, I've also used the following tag:

<fmt:message key="nav.item.name"/>

And the view shows the page, but with "???????" for the text. This is actually more acceptable to me to at least show the page, but I would rather use the spring:message tags.

My question is: How do I catch the JspTagException?

Thanks! Dave

You can't use Spring's exception handling mechanism because that is higher in the call. The JSP exception occurs later.

If you set the text attribute to some value, does it show that value instead of throwing the exception?

To clear the exception, you might provide the tag with a default message (the MessageSource.getMessage(...) method has an overload taking such a defaultMessage).

If you have no default to show but still want to warn the user about missing keys (instead of having an exception thrown or a white page), why not display the actual missing code?

You can do that by using the UseCodeAsDefaultMessage property on the MessageSource bean. See here and here.
