OK.
Here is my code. It's not from the original one because I solved that another way, so
that code is gone. But I made a "hello-world" example that does not work.....
By the way - I'm not sure if I understand you right when you asking if I can set the
value in <%...%> jsp-scriplets. Is that possible! How can I get a reference to the
"tag"-object in my scriptlets? Using the findAncestorWithClass(....) method just works
in nested tags i think. But if this is true where to script. Isn't the object just
alive between the start-tag and the end-tag. Maybe I'm on a bikeride and please let me
know If I'm wrong.
Anyway here is my example;
---------------
Here is the simple tag-class
---------------
package tagLib1;
import javax.servlet.http.*;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
import java.util.Date;
import java.io.IOException;
public class HelloTag extends TagSupport {
public int doStartTag() throws JspException {
try {
JspWriter out = pageContext.getOut();
String date = new Date().toString();
out.print("<font style=\"font-family:"+font+"; font-size:"+fontSize+";
color:"+color+"\">"+date+"</font>");
}catch(IOException ioe) { throw new JspException("IOException"+ioe.toString(); }
return SKIP_BODY;
}
public int doEndTag() throws JspException {
return EVAL_PAGE;
}
public void setColor(String color) {
this.color = color;
}
public void setFont(String font) {
this.font = font;
}
public void setFontSize(String size) {
this.fontSize = size;
}
private String color = null;
private String font = null;
private String fontSize = null;
}//end class HelloTag
--------------
tagLib1.tld looks like this (located in WEB-INF)
--------------
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"

--------------
I put this in web.xml
--------------
<taglib>
<taglib-uri>TagLib1</taglib-uri>
<taglib-location>/WEB-INF/tagLib1.tld</taglib-location>
</taglib>

This is my jsp using the tag
