Re[2]: Is there a config for JSP compiler to ignore [\s] chars in JSP directive line?
Thanks very much in advance!!!
But i think it's not a good way to do this in web.xml.
Is there any way to trim spaces when compile the jsp/servlet files but
not use the filter?

Re: Re[2]: Is there a config for JSP compiler to ignore [\s] chars in JSP directive line?
Posted by Leon Rosenberg <ro...@googlemail.com>.
its not a filter, its a parameter to the jsp servlet, which is in the
web.xml of tomcat (located under conf in 5.5) either way.
