I have a weird problem. I am using the validator plug-in of struts for doing
validations in my form. When I start my Tomcat, an error comes. This error
does not come if I delete my work folder in Tomcat and restart Tomacat. From
then on it works fine. But as soon as I restart my Tomcat, if the work
folder is not emptied this problem comes and my application does not load.
Please help.
This is the error:
