No action instance for path / could not be created.

[rob <ro...@softhome.net>]

This seems to be a fairly common problem and I have gone through
the archives prior to posting this but have yet to discover a
solution.

I'm getting that common error Error 500 No action instance for path
/login could be created.  The difficulty I'm having is that the
application was and is running perfectly fine on a tomcat 4.x
servlet container.  The error I'm observing are occuring under a
tomcat 3.x servlet container.

I'm kind of desperate here, solutions would be good.

Thanks

Rob

Re: No action instance for path / could not be created. (solved)

The reason it was biting me was because the struts.jar was in the
CLASSPATH of the user who was starting the servlet container.

Better explanation here.  So not obvious.
