Strange error when using JSF and Tomcat

[Manoj Agrawal]

Hello,

Following is the configuration we are using -

MyFaces version 1.1.3
Tomcat 4.1

The JSF application is a simple application. There is a bean called UserBean which is used for checking the authentication. The header.jsp page checks whether the user is authenticated based on this user bean.

For some strange reason, every time we restart the server, the login page gives the following NoClassDefFoundError at every alternate restart. The first time we start, everything works fine, we stop the server and restart it and go to the login page, it gives the following error -

java.lang.NoClassDefFoundError

I would really appreciate if you can shed some light on why this could be happening?
