Hello:
I am converting an existing struts based web app into an Eclipse WTP
project.
Eclipse does not like my web.xml, it gives me this error:
cvc-complex-type.2.4.a: Invalid content was found starting with element
'taglib'.
One of '{"http://java.sun.com/xml/ns/j2ee":description,

expected.
Here is my web.xml:

Any ideas why this error is occurring?

This web.xml would probably be valid for Servlet 2.3, but with Servlet
2.4, the schema requires that <taglib> elements be children of a
<jsp-config> element.
Cheers,
Larry

Larry is describing some additional metadata that tracks the "module"
version, and should be changed as well. The .wtpmodules file uses the
<module-type module-type-id="jst.web">
<version>2.3</version> attribute, make sure you change this as
well.
The servlet schema didn't change too much between these versions, so you
should be fine....
