I am being new to Jsp tag library,notunderstanding where i am making mistake.Working in WSAD 4.0.1.No compile-time error & runtime error is :JSPG0135E: No such tag example in the tag library imported with prefix etag
Tag Handler class
/* location: webApplication/WEB-INF/classes/tag/ExampleTag.class */

import javax.servlet.jsp.tagext.*;
import javax.servlet.jsp.*;
public class ExampleTag extends TagSupport
{
public int doStartTag()
{ try{
JspWriter out = pageContext.getOut();
out.println("Hello u'r in tag example");
} catch(java.io.IOException ioe)
{System.out.println("error occured at " + ioe);}
return(SKIP_BODY);
}
}

Tag Library Descriptor File
/* location: webApplicationWEB-INF/classes/tag/taglib.tld */
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE taglib
PUBLIC "-//Sun Microsystems,Inc.//DTD JSP Tag Library 1.1//EN"
