Hi,

Can anyone help me with a strange issue.

I have a simple jsp with a taglib directive.

<%@ taglib uri = "WEB-INF/myTaglib.tld" prefix = "output" %>
  | <html>
  | <body>
  | Hello
  | </body>
  | </html>

I saved the taglib at:
\jboss-4.0.3\server\default\deploy\myApp.war\WEB-INF

I saved the jsp at the root of my web application, so it is accessible as:
http://localhost:8080/myApp/myJsp.jsp

Whenever i make the slighest change in this jsp and restart my jboss server, it 
gives an error. The strangest thing is that the error comes only once. Even if 
i simply refresh the page, its gone. It only happens once when I make changes 
and restart the server at the same time.
The exception thrown is:

10:47:50,609 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception

Please note the error in bold. It is coming due to taglib directive. 

I tried following things and it worked
1> Make changes in jsp but do not restart server
2> Restart server but no changes in jsp
3> Simply refresh the page after first access

Please someone help me, it is most urgent.

Thanks in advance
