On occasion I get the exception below in the Tomcat servlet log. I am
not conversant in Java and need some kind of pointer. When the error
occurs the user's web browser seems to timeout. I suspect that an error
in the user's script is causing an error and MSP wants to display it on
their browser but cannot because of this missing class.
Other than this error the product is working well.
We are using Tomcat 3.3.1 but I got the same error from 4.1.17.
Thanks,
