Few solutions that i know :</p> <ul> <li>com.sun.jersey.config.property.packages doesn’t exist in your web.xml.</li> <li>com.sun.jersey.config.property.packages included a resource that doesn’t include any jersey services. In above case, "com.mkyong.rest” doesn’t contains any jersey services.</li> </ul> <p>So I am thinking that <strong>could it be bean.PushBean in web.xml that is wrong</strong>? <br>However, I don't know how to change it (if bean.PushBean is a problem). From eclipse project explorer, the PushBean.java path is Java Resources -> src -> Bean ->PushBean.java</p> <p>Please help me find the solution. Thanks in advance.</p>
