Hi, thanks for the attention Im trying to migrate to spring 6 and tomcat 10.1.13 but encountered many obstacles along the way. One of them is jsp. As far as I understood, it cannot resolve the path for the tag. According to the documentation for version 3, I changed all the tags from http://java.sun.com/jsp/jstl/core to jakarta.tags.core, added various dependencies and got the error below.

my dependecies:

implementation 'org.mortbay.jasper:apache-jsp:10.1.7'
implementation 'jakarta.servlet.jsp.jstl:jakarta.servlet.jsp.jstl-api:3.0.0'
implementation 'org.glassfish.web:jakarta.servlet.jsp.jstl:3.0.1'
implementation("org.apache.tomcat:tomcat-jsp-api:10.1.13")
compileOnly "jakarta.servlet:jakarta.servlet-api:6.0.0"

also tried add additional dependecies for resolve problem, but it didnt help

compileOnly 'jakarta.platform:jakarta.jakartaee-api:10.0.0'
implementation 'jakarta.servlet.jsp:jakarta.servlet.jsp-api:3.1.1'
implementation 'jakarta.el:jakarta.el-api:5.0.1'

what im doing wrong? or for what I forgot? with java ee and tomcat 9 it was easy ) error:

The problem was in context.xml I have specific tld scanner inside block after changing to new jar naming tldScan="jakarta.servlet.jsp.jstl*.jar" all works image
