applicationContext.xml is in the classpath (ie src folder),web.xml in under WEB-INF,index.jsp is under WebContent

Thanks for any help !

Answer 1

The basic problem is you mixed up xml and annotationConfigs. You need to know the relation between contextClass and contextConfigLocation context params and how ContextLoaderListener will make use of it.

1. contextClass : refers the configuration class. You mentioned here it as org.springframework.web.context.support.AnnotationConfigWebApplicationContext
2. contextConfigLocation : this is the location where it spring's bootstraper will search for config. You specified contextClass as AnnotationConfigWebApplicationContext, for that you should give the package name where your Spring bean configuration class resides.I assume you have such class annotated with @Configuration

If you have no such @Configuration annotated class remove contextClass and put only contextConfigLocation param with your xml path as value. By default ContextLoaderListenertake the xml based. Here is an example of migrate to java config from xml based spring

You can find a ready to adapt example of jersey integration here.

Next thing I still confused, why you are using RequestContextListener for REST application. If you don't have any special purpose as per its documentation remove it. If you want to use it this example will help

Also find some useful detail regarding the question here

Answer 2

I finally found the solution for my question , i was mixing the jersey1.x and jersey2.x maven dependencies (that of sun and glassfish
