Errors trying to integrate existing Dynamic Web Project [message #1857862] Thu, 02 March 2023 13:44 Go to next message

I created a dynamic web project last year on an earlier iteration of Eclipse (6/2020). However, due to my laptop being reimaged and serviced recently, I had to reinstall Eclipse, and, this time, I chose Eclipse IDE for Java Developers.

I pointed to the directory where my old dynamic web project was, and while it integrated relatively OK, I have since run into multiple problems.

1) All of my JSPs won't compile due to errors involving JSTL: Cannot find the tag library descriptor for "http://java.sun.com/jsp/jstl/core" (also for "fmt" and "fn"). I imported jstl.jar into the Classpath via Java Build Path, cleaned the project, even restarted Eclipse, all to no avail.

2) Although I struggled with installing JBoss 6.x Runtime 1 Server, I was finally able to install and implement it, however, I am unable to start the server:

Error: Could not create the Java Virtual Machine I am using JDK 14.0.2

I am unable to proceed further with the dynamic web project and need help.

Thanks

I would expect you to install the Eclipse IDE for Enterprise Java and Web Developers which says "Tools for developers working with Java and Web applications, including a Java IDE, tools for JavaScript, TypeScript, JavaServer Pages and Faces, Yaml, Markdown, Web Services, JPA and Data Tools, Maven and Gradle, Git, and more." The "Eclipse IDE for Java Developers" does not have the tooling for web development.

JDK 14.0.2 seems a weird choice. You're probably better off with JDK 17 which is a LTS (Long Term Support) version:

Ed's right, although you can add those features from the directions on https://wiki.eclipse.org/WTP_FAQ#How_do_I_install_WTP.3F .

What's odd is that that Problem message requires at least some of it to be installed already. If that is the case, and you have the JSP Editor
available, does it offer valid URIs via Content Assist inside the taglib directive's URI value?
