custom taglib ; SKIP_PAGE does not work As I expected

[Killeroms kleos]

Hi all,

I have a problem with my taglib, In case of error I want to display something one the page before stopping processing the rest (this is kind of a rest web service and i want to display errors in xml )


in my tag class I override the doEndTag method like this:

   
public int doEndTag() throws JspException {
   int errors = checkErrors();
   if( errors != 0){
      pageContext.getOut().print(getXMLErrors());
      return SKIP_PAGE;
   }
   RETURN EVAL_PAGE

But unfortunately when I use SKIP_PAGE nothing is written to the page (this seems to mean: stop processing page and do not ouput anything from this tag)

I tried to flush before the return statement but it is not allowed.

Do you have any idea of how do it ?

Killeroms,
Welcome to JavaRanch!

How about throwing a JSP Exception which would direct you to another page that displays the error messages.

Or a more MVC solution where you call the web service from a servlet (or delegated class) and the JSP knows if there is an error before painting the page?
