Custom tags outputting a JSTL tag

2003-05-27 Thread Danilo Luiz Rheinheimer 
Hello,

  I have a custom tag, and I want to output a JSTL tag on it.
  But this new tag is not processed.

  Like this :

  public int doStartTag() throws JspException {
try {
  JspWriter out = pageContext.getOut();
  out.println(c:out value=\y\/);
}
catch (IOException ex) {
}
return EVAL_BODY_INCLUDE;
  }
  
  Any help ?

This can't easily be done because the JSP container won't interpret your
output as tags.  You could walk through the various steps that the JSP
container performs to invoke c:out -- e.g., instantiate a handler, call
the accessors, call doStartTag(), and so forth -- but that's
extraordinarily tedious.

An easier solution might be to use the RequestDispatcher to include a page
that contains the tag you want to include, parameterized by request
attributes.  This leads to a better design anyway, where output stays the
responsibility of JSP pages.
