anyone help me please, thanks !

Hi,

Seems you are having some problesm migrating to struts 1.1.
I believe some jar which are required by struts are not available.Why don't you download the struts package once again and deploy your application.Check that your struts-confix andweb xml files are wellformed.

Cheers
