You should be able to directly access the JSP implicit objects, e.g. cf. , if using the ScriptTagLibs library [1], and all of their methods. Therefore you should be able to do something like this: <%@ taglib uri="http://rexxla.org/taglibs/jsr223" prefix="s" %> 40_helloworld_use_request.jsp: Sample Application JSP Page Using JavaScript Via JSR-223 (Title) out.println("

Hello, world (JSP with Nashorn/JavaScript)

"); // implicit JSP object 'out' print("

This JSP was executed, because of the following URL:" , "

URL request.getRequestURL():
" , // implicit JSP object 'request' request.getRequestURL(), ""); print("
its URI being request.getRequestURI():
" , // implicit JSP object 'request' request.getRequestURI(), "

Message-ID: I do not get an exception. When opening the JSP in the Browser I see that there is no Cookie created. The Code I am using: var lastVisit; var allCookies = request.getCookies(); if (allCookies != null) { for (var i = 0; i < allCookies.length; i++) { var c = allCookies[i]; if (c.getName() == 'lastVisit') { lastVisit = c.getValue(); } } } if (lastVisit == null) { print("This is your first Visit!"); } else { print("Your last visit was at " + lastVisit); } var Cookie = Java.type("jakarta.servlet.http.Cookie"); var newCookie = new Cookie("lastVisit", "Test"); response.addCookie(newCookie); Using request and response is possible due to this taglib: https://sourceforge.net/projects/bsf4oorexx/files/Sandbox/rgf/taglibs/ga/ Best Regards Simon Am Mi., 9.

Message-ID: Here is a short update on the case. Nashorn is working as expected. request.getCookies() works, as well as to create an instance of the class Cookie. For example, after creating the cookie I can use getName() or getValue() and it works perfectly fine. The issue that I had with not seeing the cookie in the browser still exists, but that seems to be unrelated to Nashorn. Best Regards Simon Am Mi., 9.
