A error occured on JSP custom tag...

Hello all,
I am using a custom tag - that uses a JavaScriptDate bean...i did test it separately it works fine in a Jsp page...
Now, I created a Tag class as JavaScriptDateTag.java that has the following code:
class JavaScriptDateTag extends TagSupport {
public int doStartTag() {
try {
JspWriter out = pageContext.getOut();
JavaScriptDate now = new JavaScriptDate();
out.write(now.getScriptDate());
} catch (IOException e) {
System.out.println("Error in JavaScriptDateTag" +
e.getMessage());
}
return TagSupport.SKIP_BODY;
}
}
----
I also included this tag in JavaScriptDateTag.tld file...as today. this file contains one more tag "message" :
<tag>
<name>today</name>
<tagclass>vlv.mserver.mtags.JavaScriptDate</tagclass>
<info>Display current date</info>
</tag>

<tag>
<name>message</name>
<tagclass>vlv.mserver.mtags.JavaScriptExampleTag</tagclass>
<info>Display Alert Box</info>
</tag>
-----
Now i tried in a JSP page i get an error as follows:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 5 in the jsp file: /jsps/tester.jsp
Generated servlet error:
D:\tomcat4.0.6\work\Standalone\localhost\iqc\jsps\tester$jsp.java:60: Method setPageContext(javax.servlet.jsp.PageContext) not found in class vlv.mserver.mtags.JavaScriptDate.
_jspx_th_js_today_0.setPageContext(pageContext);
^
----
The code in jsp page:
<%@ taglib uri="http://www.jsp.com/jspkit/javascript" prefix="js" %>
<html>
<body bgcolor="#ccffff">
Hi, <br> Here follows today's date:<js:today />
<js:message>Hello</js:message>
</body>
</html>
-----
I have refered many books and couldn't get a solution to over come this ...
Anyone pl. guide me... Thanks a lot

Hello all
Thanks a lot , i found the error it was in the "*.tld" file, the <tagclass> tag was pointed to the Javabean instead of the Tag class. Following is the correct code in tld file:
<tag>
<name>today</name>
<tagclass>vlv.mserver.mtags.JavaScriptDateTag</tagclass>
<info>Display current date</info>
</tag>
