Strange error when using JSF and Tomcat
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 -

I would really appreciate if you can shed some light on why this could be
happening?
Re: Strange error when using JSF and Tomcat
Posted by Martin Marinschek <ma...@gmail.com>.
Usually, you'd see the name of the managed-bean-class that could not
be instantiated. In your case, you see an empty string. That would
mean you've configured a managed-bean with an empty string as
class-name?
regards,
Martin
