"Migrating Java Web Application from Eclipse to MyEclipse 2016: Issues with GlassFish and Tomcat"

Hello everyone,

I have a Java-based web application that is currently being developed in Eclipse and deployed using GlassFish 4. I am trying to migrate this project to MyEclipse 2016, but I am encountering numerous errors.

Here are the main challenges I am facing:

Unable to Run the Application on GlassFish 4 in MyEclipse:
The application fails to start, and I encounter various configuration and runtime errors.

Attempted to Deploy on Tomcat 8.5:
Since I couldn't run the application on GlassFish, I tried switching to Tomcat 8.5. However, I am encountering several issues related to dependencies and library conflicts.

Given these challenges, what would be the best approach to successfully migrate and deploy my application in MyEclipse 2016? I look forward to the resources you recommend.

Welcome to the Ranch, Yahya!

You do realize that Eclipse 2016 is nearly 10 years out of date, don't you? Tomcat 8.5 hasn't received security updates for nearly a year now and will probably be formally declared dead in no more than 6 months.

Just because you have an old app doesn't mean you should be using old tools. You won't find any support for them.

Also, you cannot just toss Glassfish code into Tomcat, regardless. Glassfish is a full-stack server and Tomcat is not. Significant changes are required between them.
