spring mvc project "invalid character used in text string" error in .jsp file

Question

I want to share my sample code in my website. And I used Punctuation marks(such as; &, *, % etc.) in jsp file like below;

<pre>
/*
if(sensB>sensA && diffB>200)
{
ctr++;
delay(2500); // INCREMENT
}
*/
</pre>

But I had got warnings;

Description Resource Path Location Type Invalid character used in text string (/if(sensB>sensA && diffB>200) { ctr++; delay(2500); // INCREMENT }/)

How can I get this error?

if you use the pre tag to display code, the HTML encoding/escaping is required. — Monzurul Shimul, Feb 01 '17 at 09:17

As shi metntioned in the comment you need to escape your content (code string) in JSP

<c:out value="${myCodeString}"/>

there is another option:

<%@taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
${fn:escapeXml(myCodeString)}
