and here error when try view resource either in eclipse or on chrome:
the code in web.xml needs correction.
<init-param> <param-name>com.vogella.web.resources</param-name> <param-value>com.vogella.web.filecounter2</param-value> </init-param> the param-name , param-value fields not correct. change param-name jersey.config.server.provider.packages , param-value com.vogella.web.resources.
the correction should
<init-param> <param-name>jersey.config.server.provider.packages</param-name> <param-value>com.vogella.web.resources</param-value> </init-param>
