Does instanceof work?

I've tried the Struts logic and the JSTL tag version of instanceof, like these (below), but get errors returned implying that instanceof doesn't exist as a valid option. Does it exist? Am I doing something wrong? Can someone give me an example, please? Thanks, Frank. *** examples ***

Recommend file upload progress bar

I have a requirement to display a progress bar while performing file uploads. I've found several frameworks that provide this functionality. However, can you recommend an existing *best* solution -- preferably off-the-shelf -- for use with Struts? Thanks, Frank

ActionForm necessary?

I have a jsp form which has fields that require no validation. So I don't need to validate the form input. If I don't include an ActionForm, I get a ... null form ... error message. Does this mean that I MUST create ActionForms, even if they are empty -- i.e., no validate() method and no

Strange behaviour?

I have a validate() method in my ActionForm class that includes some cleanup (removes redundant whitespace) of some of the ActionForm bean's properties. The related Action has validate=true set in struts-config. So validate() should always be called. The Action class then uses the ActionsForm's
