So, you got two JSP pages, and the first page includes the second one (head.js), right? Or, you want to include a JSP page from a ZUML page?

It will be clear if you post some psuedo codes to illustrate your use.

Remember if you encountered any problem, try to disable zkFilter first, and save the generated HTML pages (from jsp). Then, rename it to whatever.zhtml and load it thru zkLoader.

How did you map zkFilter (filter-mapping)? Did you map it to INCLUDE? If so, the included JSP page will be interpreted twice.

Hi,

I also have issues attempting to make use of the zkFilter. Adding the filter configuration to my web.xml results in a long list of exceptions at tomcat start-up before any page requests. Any help is highly appreciated!

No blank line or space is allowed before the <?xml ....?>

It must be the first line.

Never mind. I forgot to add the xml header to EVERY jsp fragment file.

But thanks!!! The only thing at this time would be a display tag / extremeTable like control, and more importantly the huge performance penalty for using the zkFilter.

Where is all this time lost? There's a minimum 2-3 second penalty per page load for using the filter. Interestingly, it is the same for every page load!?!, not just the initial load as it usually is with jsp pages.
