Re: Apache Tomcat 10.1.6 is giving me java.lang.ClassNotFoundException: jakarta.servlet.jsp.JspFactory
Hi Chris, I have forwarded you that SO URL to showed you that the scope provided needed to add it in but after you pointed out I realised it is wrong. Nope. I am not using jetty run. I right click on Eclipse run on server. 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. | | | | Download jakarta.servlet.jsp-api JAR file with all dependencies Download jakarta.servlet.jsp-api JAR file ✓ With dependencies ✓ Documentation ✓ Source code | | | and Tomcat is able to run. Only thing is that the index.jsp doesn't show up. It only show localhost:8080/webclientv1/ and the browser appears moving like waiting. 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 ? Tks.

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. Tomcat really should be prohibiting that class from being provided by an application, but maybe you have put it somewhere that is confusing the JVM. Which lib/ folder did you put those JARs into? -chris - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
