New resource: Bugs every servlet programmer should know about
I just posted on Servlets.com a new resource listing the top bugs a
servlet/JSP programmer should know about. They're culled from my email
inbox, based on the most
frequently reported problems sent to me by users. Several directly
involve Apache/Tomcat, so I thought this would be a good forum in which
to post a mention.

If you know of other similarly "high profile bugs", please let me know.

Jason,
The first bug in the list, about file upload problems with AJP13 was fixed
in 3.2.3.

Good suggestion, Craig. I've updated the list to include this.
I also incorporated all the other comments from the people who wrote
me. Glad to see the ajp13 issue is fixed in 3.2.3!

Jason,
One "family" of bugs you might want to include pertains to app servers
that still use the Jasper engine from Tomcat 3.1 in their current
production versions (such as IBM's WebSphere 3.5.3 and earlier). Such
servers inherit a large number of bugs from that Jasper code -- one that
bites many users is the fact that this Jasper does not let you use
pageContext.removeAttribute() to remove an attribute from request scope.

You forgot: never use servlet instance variables.
This alone is the most common servlet programming bug I've
ever seen, and I see it again and again and again.
I think the containers should use reflection to sniff
a servlet class and if there is a servlet instance variable,
refuse to load the class.
But that's just me.
