RE: cannot run simple servlets with tomcat 3.3.rc1

[Larry Isaacs <La...@sas.com>]

I can duplicate this error if I remove JspInterceptor.
It appears that InvokerInterceptor is dependent on some
initialization being done in JspInterceptor.  Was
JspInterceptor removed in your server.xml?

Cheers,
Larry
