I have created a maven webapp and I'm trying to use the restful services and a JBoss 7.0 runtime.
I've changed the web.xml to call the restful services using javax.ws.rs from which I have also added the jar to the build path. The server starts perfectly, so there is no errors or failures in related to the web.xml file and I can successfully call the first page.
I've wrote a class called RestService which is supposed to do something when I call another URL (to be precise localhost:8080/myPrj/rest/hello/first), but when I call the URL it shows an error on my eclipse console and on the web browser.
What am I doing wrong?
Please help a newbie
this is my web.xml
