#39853 — struts2 syntax

Anyone know this framework? I can't find any documentation or examples.
We were including javascript in JSP like this, which was generating a CSP security error:
<script src="<s:url value="/js/myScript.js"/>"></script>

I tried just changing it to the struts tag and it just crashed:
<s:script src="<s:url value="/js/myScript.js"/>"></s:script>

So I'm trying to figure out if this can be done as a one line command, as it does work as a two line command:
<s:url var="myScriptjs" value='/js/myScript.js' encode='false' includeParams='none'/>
<s:script src="%{myScriptjs}"/>

I don't know Struts 2 (I did a bit of Struts 1 a very long time ago,
but Struts 2 is not based on Struts 1 but on WebWorks).

Anyway, what is the problem you need to solve. Aka why not just:

<script src="/js/myScript.js"></script>

?

Do you need it to insert the web app name so it becomes:

<script src="/foobar/js/myScript.js"></script>

automatically if it is deployed in foobar.war?

I'm new to this struts project myself, my previous project just used spring framework, so the s:url part was already there I'm assuming needs to be there.
Seems likely this relative path url will end up inserting the war name.
I haven't found much for documentation on these struts tags, mostly figuring out through trial and error. I could try the direct path without the s:url and see what it does.
It could respond differently in eclipse embedded tomcat versus building a war and running it outside of eclipse, assuming that war will run the same on my tomcat or another machine.
In the Spring project I was on I did write some JSP links using JSTL url tag, seems like this should be the same thing. https://www.w3schools.blog/jstl-curl-core-tag
