Trying to access a REST web service

[DanSchwartz]

I am in process of upgrading from Glassfish 4.1 to the current version 7.0.25. Glassfish 7.0.25 is running, and when I drop in the .war file that works with Glassfish 4.1, it deploys, but when I try to access it with my test URL, I get:

---

HTTP Status 404 - Not Found
type Status report

messageNot Found

descriptionThe requested resource is not available.

Eclipse GlassFish 7.0.25

Would anyone know why this is happening? Do I need to make code changes to make this work with the newer version of Glassfish?

This is very likely because of the changes in Java package prefixes in Jakarta EE. Read this guide to help you upgrade to GlassFish 7: https://omnifish.ee/how-to-upgrade-to-jakarta-ee-10-and-glassfish-7/

Ondro, Thanks. This sounds like what I need. I’ll have a look.
