Hi,
I am trying to deploy a test app with jersey 2.0 in tomcat 8.5, which has only one service When I try to access the service getting this error :

java.lang.IllegalStateException: No generator was provided and there is no default generator registered   
at org.glassfish.hk2.internal.ServiceLocatorFactoryImpl.internalCreate(ServiceLocatorFactoryImpl.java:308)

at org.glassfish.jersey.internal.inject.Injections.createLocator(Injections.java:123)   
at org.glassfish.jersey.server.ApplicationHandler.<init>(ApplicationHandler.java:330)

I am using the jersey jars 2.25.1. What could be the cause of this error?

Thanks, Prasad. I have added all jersey2 dependency jar in WEB-INF/lib it's working. but **when I change all the Rest Service Classes in WEB-INF/classes folder, instead of placing the jar in WEB-INF/lib** but getting this error. Am trying to resolution for the below issue, there is an issue when I deploy the jersey2 service in WebSphere-8.5. Please look into the link [link](https://stackoverflow.com/questions/62890157/jersy2-0-service-deployment-issue-java-lang-nosuchmethoderror-javax-ws-rs-core) !!!Thanks once again !!! — Stalin, Jul 16 '20 at 07:55
