servlet not found when upgraded to resin 2.0.5

[christine lorraine]

hi,
did anyone experience a problem with servlets when they upgraded to resin 2.0.5.
my servlets were perfectly running until my hosting provider upgraded to resin 2.0.5. my web application is located in a subdirectory inside public_html. and now the servlets can not be located and my other classes as well.
i have 3 web applications in public_html each have its own directory.
thank you very much.
