Thank you for your response.
I'm using NetBeans 17 as the IDE, with Java 21, and running the
application on Tomcat 10.0.20.
The issue occurs when I try to run the web application from within the
IDE.
NetBeans shows the following error when the issue occurs:
The s:form tag declares that it accepts dynamic attributes but does
not
implement the required interface

While migrating to Struts 7.0.0, I'm encountering an issue when
using
the
<s:form> tag. Even though the tag is present like this
jsp
<%--<s:form></s:form>--%>
I’m getting the following warning or error:
The s:form tag declares that it accepts dynamic attributes but does
not

It would be good to provide more details, when does it happen? What
Java version do you use? Is this in an IDE or when running a webapp
in
a container?
There are a bunch of examples which are working just fine, so I
assume
it's something wrong with your setup.
