I have been trying to deploy and run a Jersey2 based REST application on WebSphere ND 8.5. However, it refuses to start up properly and gives the following error:
com.ibm.ws.webcontainer.servlet.ServletWrapper run SRVE8052E: Logging ClassNotFoundException java.lang.ClassNotFoundException: org.glassfish.jersey.servlet.ServletContainer
I tried going through most of the related questions, but none of it was helpful in figuring out the problem.
Some of the links I tried:
java.lang.ClassNotFoundException: org.glassfish.jersey.servlet.ServletContainer - Accepted answer talks about ensuring the jars are present in WEB-INF/lib. My project is already a Maven project, and dependencies are correctly bundled:
JAX-RS Jersey 2.10 support in Websphere 8 - Setting com.ibm.websphere.jaxrs.server.DisableIBMJAXRSEngine to true in JVM properties did not help
- WebSphere 8.5.5.9 with Jersey 2.25 - Has same suggestions as above
As of now, on my local setup the EAR file runs correctly, on a Liberty profile server (embedded in Eclipse). Maven build works fine, and libraries are copied correctly.
One discrepancy I am aware of is that I am using Jersey2.xx, still with the entries in web.xml. But I am not sure how that could cause a ClassNotFoundException.
web.xml for reference:

The weirder thing is this application was at least starting up without this error couple of days back, before an admin "manually removed old files" before re-installing this app on server. This makes me think there was some configuration which got removed/reset during that process which caused this.
How can I make this EAR run without getting this exception on WAS ND 8.5?
Edit: adding full stack trace. I have set the class loading as PARENT_LAST, so I guess it should be using the module's class loader?
