Nobody should ever use such a filter: it completely clobbers the
response content type and character set, and does so for *every
resource served by the application*.

Did you recompile/reinstall?

Hello,

Indeed, I have such a filter:
In "web.xml":

servletResponse.setContentType("text/html; charset=" +
Finals.S_CHARSET);
servletResponse.setCharacterEncoding(Finals.S_CHARSET);
filterChain.doFilter(servletRequest, servletResponse);
}
Commenting the line:
servletResponse.setContentType("text/html; charset=" + Finals.S_CHARSET);
doesn't solve the problem.
I still get the error:
The stylesheet http ://localhost/fr/css/fo.css was not loaded because itsMIME type,
“text/html”, is not “text/css”.
Also note :
https://tomcat.apache.org/tomcat-9.0-doc/servletapi/javax/servlet/ServletResponse.html#setCharacterEncoding-java.lang.String-
says :
"...calling this method with the String of UTF-8 is equivalent with calling setContentType
with the String of text/html; charset=UTF-8."
So, in the above, if you have just commented-out the line :
servletResponse.setContentType("text/html; charset=" +
Finals.S_CHARSET);
but you left the following line unchanged
servletResponse.setCharacterEncoding(Finals.S_CHARSET);
then executing this line is equivalent to setting the content type to
"text/html".
And this looks suspiciously like the error you are getting..
As another way of avoiding that problem, you may also want to change in web.xml
:
> /*
by something that applies *only* to HTML responses.

Hi Lea,
I experienced this problem not so long ago when we upgraded our Tomcat to a later
version of 9. Basically we had a filter applied to requests which was supposed to set
the encoding of the response to be UTF-8. However, it was also setting the content type
to text/html.
Previous to the Tomcat upgrade it wasn't an issue. I found that in one of the Tomcat
updates (can't remember which one) the logic of the default servlet was altered such
that if the content type has already been set in the response it can't be set again
further down stream. So my resolution was to remove the line that set the content type
in our filter.
Something to check anyway as it took me some time to figure out what was
happening.

Betreff:Tomcat9, JSP, CSS and JS not loading in Firefox
Hello,
My question is about loading a JSP page in Firefox (or Google Chrome) and
not having the CSS loaded and the JS operational.
I am using Tomcat v9.0 and Eclipse Java EE IDE v.2019-12 (4.14.0).
When I'm developing using Eclipse IDE, I usually:
- select a JSP in the "WebContent" directory in the Eclipse workspace,
- right-click,
- select "Debug/Run As -> Debug/Run on Server"
and the Webapp starts debugging/running.
With the URL "http ://localhost//.jsp", the page gets
displayed correctly in the Web browser that Eclipse "embeds" (maybe I.E.,
I
don't know).
In Internet Explorer, the page is displayed correctly too.
Now, if I copy this same URL "http ://localhost//.jsp"
in
Firefox or Google Chrome, it's like the CSS is not applied to the page,
and
the Javascript code doesn't run when it should.
Note that I didn't use to have that problem before I upgraded Eclipse and
Tomcat (I used Tomcat v.8 before).
Below is the beginning of the JSP page:
--
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http ://java.sun.com/jsp/jstl/core"%>
${initParam['S_IF_MSG_TITLE_WELCOME']}
--
Also in Firefox, I pressed Ctrl + Shift + k and saw the error message:
--
The stylesheet http ://localhost/fr/css/fo.css was not loaded because its
MIME type, “text/html”, is not “text/css”.
--
and the warning:
--
The script from “http ://localhost/fr/js/fo.js” was loaded even though its
MIME type (“text/html”) is not a valid JavaScript MIME type.
--
Can you help me solve that problem?
Best regards.
