Access spring environment aware variable in jsp

Question

My environment variables are managed via spring profile and i have an xml that contains the entry below...

<context:property-placeholder location="classpath:/properties/app_config_${spring.profiles.active:dev}.properties" />

In the file app_config_dev.properties file, i have the entry below: otherApp.baseurl=devEnvt.mainApp.com.au

In the backend, i have a Service object and the variable is annotated by @Value to take advantage of spring taking care of getting the value via the property file in which the application is deployed in (can be dev, staging or prod).

@Service
@Slf4j
public class AppService {

   @Value("${otherApp.baseurl:https://test..}")
   private String baseUrl;
}

In the front end, i have this index.jsp that basically just redirects to a url.

<%

Account acc = Account.getAccount(session);
String url = request.getScheme() + "://" + "url_value_from_environment_aware_property_file" + "/reset";//url_value_from_environment_aware_property_file should be equal to otherApp.baseurl

if (acc != null){
   JSPUtil.contentInclude(pageContext, "error_loggedin.jsp");
}else{
   response.sendRedirect(url);
}

%>

My question is, given that I have a very basic jsp here, how can I access the environment aware variable that is being managed by Spring?

We use ServletContextListener to load the properties file at the server startup as given here.

We have defined the context-param to activate the profiles for a web application.

<context-param>
   <param-name>spring.profiles.active</param-name>
   <param-value>web,jpa</param-value>
</context-param>
