How to properly escape this JSP code to avoid Stored XSS valnerabilities?

Question

These are flagged as having "Stored XSS vulnerabilities". Need to know how to properly escape the following to address this type of cross site scripting vulnerability?

out.print("<td headers=\""+headerIDs.get(i-1)+"\""+ (wrap?"":"nowrap")+">"+StringUtils.isNotEmpty(value)? value : "&nbsp;"+"</td>");

out.print("<td headers=\""+headerIDs.get(i-1)+"\""+ (wrap?"":"nowrap")+">"+StringUtils.escapeXML(value, "&nbsp;")+"</td>");

I've seen a couple possible solutions but not sure which one is the better one?

StringUtils.renderSafeHtml(...)

Encoder.forHtml(...)

My teammates are using renderSafeHtml(...) to address the other kinds of XSS vulnerabilities in our code, so I prefer to use this one. However, all the examples I've seen online suggest Encoder.forHtml(...) for "Stored XSS".

Bear in mind org.springframework.web.util.HtmlUtils.htmlEscape is not an option since we use Struts.
