Fw: Apache Tomcat 10.1.6 is giving me java.lang.ClassNotFoundException: jakarta.servlet.jsp.JspFactory
Hi experts, I am not getting reply on this jakarta.servlet.jsp.JspFactory, can I have some feedback how to make Tomcat works with the libraries I need ?

I am not using jetty run. I right click on Eclipse run on server. Maybe I'm getting confused by what is copy/paste from your (unreferenced) sources and what is your own words. Your posts are difficult to interpret. So, the latest happening is that I got an advice from another SO user to put in the jar from Download jakarta.servlet.jsp-api JAR file with all dependencies I tried to exploded the jar to see if it contains all the dependencies I need but all i could find is byte code .class. JAR files typically only contain .class files. If you see a file in there with the class name + ".class" then that's where the class is. If you are providing a JAR file which contains jakarta/servlet/jsp/JspFactory.class then you are making a mistake and need to remove that file from your application.

Only thing is that the index.jsp doesn't show up. It only show localhost:8080/webclientv1/ and the browser appears moving like waiting. This is different than ClassNotFoundException. Unless this is the behavior of the client while the log file shows "ClassNotFoundException". But, still I got to sort out the dependencies cos I need them for CICD. Could you advise me what is the full set of dependencies I need ? Tomcat should provide jakarta.servlet.jsp-api and so you do not need it. If you want to add JSTL to use that in your JSPs then you need only the JSTL library and any of its dependencies (but not JSP-API, which is provided by Tomcat). -chris On Thursday, March 2, 2023 at 01:51:56 AM GMT+8, Christopher Schultz wrote: Karen, On 3/1/23 10:21 AM, Karen Goh wrote: hi Chris, I am following advice from ClassNotFoundException: javax.servlet.jsp.JspFactory ClassNotFoundException: javax.servlet.jsp.JspFactory I have a maven-based app that I copied exactly and tried to run mvn jetty:run And now getting this error:Cau... where it says scope provided must be added Anwyay, I have removed the scope and the jars that are put in the lib folder in WEB-INF, it is no use.

Your POM shows both jstl artifacts as "provided" meaning they won't be downloaded and bundled into your application. I think you actually need to allow those to be downloaded as they are not provided by Tomcat (I think! I'm no JSTL expert). But Tomcat definitely ships with a copy of jakarta.servlet.jsp.JspFactory so if you are adding a JAR which contains that class, you are likely causing a conflict.
