Hi Guys,We are almost ready to go into final testing on our Struts 7 app migration, except for a small issue when we render JSON responses and we can't work out where the issue is.
The problem presents when we try and render JSON response to a jsp page, but only when going through an action first. I should stress this works fine on tomcat 10 using the same build of Struts and SiteMesh.
As a simple test we created a method on our action class which sets a page accessible parameter to a long sample JSON string:
public String ajaxTest(){
ajaxResponse = " [{\"name\": \"Adeel
Solangi\",\"language\": \"Sindhi\",\"id\": \"V59OF92YF627HFY0\",\"bio\":
... I have attached the full JSON text but cropped in the email for clarity
return SUCCESS; }On the resulting jsp page, see below, it results in the JSON string being cropped and the browser complaining of invalid JSON:
<%@ page contentType="application/json; charset=UTF-8" %><%@ taglib prefix="s" uri="/struts-tags"%><s:property value="%{ajaxResponse}" escapeHtml="false"/>
We also tried using JSTL tags which has the same result:<%@ page contentType="application/json; charset=UTF-8" %><%@ taglib uri="jakarta.tags.core" prefix="c"%><c:out value="${ajaxResponse}" escapeXml="false"/>
The strange part is if we set the variable in the JSP page and just call the page directly via testPage.jsp it works as expected:
<%@ page contentType="text/html;charset=UTF-8" language="java" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%> <s:set var="ajaxText">[{"name": "Adeel Solangi","language": "Sindhi","id": "V59OF92YF627HFY0","bio": "Donec lobortis eleifend condimentum. ...
</s:set><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en" lang="en"> <head> <title>SpareEngine</title> <meta http-equiv="Content-Type" content="text/html;charset=utf8" /> </head> <body> <div class="main-body"> <s:property value="%{ajaxText}" escapeHtml="false"/> </div> </body> </html>Because the plain JSP renders correctly I don't think it is a tomcat issue, but I can't be certain. Any help would be appreciated.
