org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization.

[JavaNeed]

Hello,

I was facing the below error. Could you please guide on http://stackoverflow.com/questions/39405067/org-glassfish-jersey-server-model-modelvalidationexception-validation-of-the-ap too ?

The error for reference:-

org.glassfish.jersey.server.model.ModelValidationException: Validation of the application resource model has failed during application initialization.
[[FATAL] A resource model has ambiguous (sub-)resource method for HTTP method GET and input mime-types as defined by"@Consumes" and "@Produces" annotations at Java methods public java.util.List br.com.alexandreesl.handson.rest.ProductRest.getProducts() and public java.util.List br.com.alexandreesl.handson.rest.CustomerRest.getCustomers() at matching regular expression /. These two methods produces and consumes exactly the same mime-types and therefore their invocation as a resource methods will always fail.; source='org.glassfish.jersey.server.model.RuntimeResource@14c14bf']
