OT: Tomcat struts-2.0.9 noClassDefFoundError

I know this is a little off topic but I'm lost as to where to start.

We're currently working on an app and when I went to start Tomcat this
morning I got a java.lang.NoClassDefFoundError: javax/servlet/Filter.

This installation has been working fine for months and the only change was
when I upgraded the struts jars to 2.09 this morning.

I tried going back to 2.08 but that hasn't solved the problem. I tried
googling with no luck.

My environment is:

Tomcat: 6.0.10
JVM: Apple 1.5.0_07-164

The Servlet-api jar looks fine and as I sad it was working perfectly
yesterday. Any help would be so appreciated at this point.

Z.

PS here's the detailed stack trace:

Hi Dale,

I should preface this by saying that we have only used Tomcat 6 and have
found it to be great, no issues until this. Solid, fast, no complaints at
all.

I found a post on the Tomcat Users list from Frank Zammetti which looked
pretty similar, which meant it wasn't a Mac issue (phew). Frank seemed to
think it was a 6.0.10 issue and I agree. I think that there is something NQR
there.

I couldn't help myself so I tried a few things. I did a touch on the
servlet-api.jar and it started working. Talk about scratching my head.
Anyway both are now working absolutely fine, so I don't know where to from
here. I guess we go into staging next week and if we don't run into any
issues during the 5 weeks of staging we'll take tomcat through to
production.

I have a project I've been developing against tomcat5.5, but I've been 
considering deploying to tomcat6 in order to get JSP 2.1, mainly in 
order to be able to set: 
<trim-directive-whitespaces>true</trim-directive-whitespaces>.

But I also don't know much about tomcat6...
...so I'm also quite interested in learning about the experiences of 
folks here on this topic.

Just a quick update on this. After spending the better part of the day and
in complete desperation (please, let get my frustration out) I downloaded
the latest version of Tomcat (6.0.13 as opposed 6.0.10 previously) and it
all worked fine.

WTF is that about. This untouched setup has been working fine for months -
as I said, all we changed were the upgraded struts jars.

This is my first project we're we'll be using Tomcat in preference to a
commercial product and I'm a little concerned about it's stability.

Does anybody have any experience with Tomcat 6. Should I be downgrading back
to 5.5? This project is slated to go into production in 6 weeks and the last
thing I want is a similar issue a few months into its deployment.

Z.
