Re: Possible to programmatically create and use tags?

[Paul Benedict]

No, that is not possible. This is not a limitation of Struts, but because of 
the way JSP is constructed. 

JSP Engines scan the swiping <% %> as real code, and invoking JSP tags  -- the 
rest is simply out.println() statements. You cannot do what your saying because 
the JSP Engine would have to take two passes to produce your JSP: first to get 
the created page, the second to then do it again.

If you need to do conditionals, do something like this:
<c:if test="${condition"}>
  struts tags here
</c:if>

Is it possible to programmatically create HTML blocks that include struts
tags and include them in a JSP?

Here's a simple example which fails to produce the text field defined by the
html:text tag:

------------
<%@ page language="java" errorPage="ErrorPage.jsp" contentType="text/html"
%>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>


    
        

    

    
<%
    try {
 StringBuffer sbuf = StringBuffer();
        sbuf.append("");
        sbuf.append("   ");
        sbuf.append("     Employee Name: ");
        sbuf.append("     styleClass=\"FORM_FIELDS\" >");
        sbuf.append("     ");
        sbuf.append("   ");
        sbuf.append("");
        String variableHeaderHTML = sbuf.toString();
%>
 

          

            <%= variableHeaderHTML %>

          

 
<%
    }
    catch(Exception ex) {
        System.out.println("ERROR: " +ex.toString());
    }
%>
