I am new to PrimePush and want to try it. I followed this tutorial
However, when I ran the register.xhtml file, I got the error com.sun.jersey.api.container.ContainerException: the ResourceConfig instance does not contain root resource classes.
This is the jar that I have
- atmosphere-Compat-jbossweb-1.0.1
- atmosphere-compatible-1.0.1-cat
- atmostphere-Compat-tomcat7-1.0.1
- atmostphere-environment-1.0.1
- primefaces-3.4.2
- SLF4J-api-1.7.2
- SLF4J-simple-1.7.2
- JSF 2.1 (Mojarra 2.1.6)
I am using tomcat7 and jre7
This is web.xml

This is register.xhtml
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:p="http://primefaces.org/ui" xmlns:h="http://java.sun.com/jsf/html"> <h:head> <title>Facelet Title</title> </h:head> <h:body> <h:form id="form"> <h:outputText id="out" value="#{pushBean.count}" styleClass="ui-widget display" /> <br /> <p:commandButton value="Click" actionListener="#{pushBean.increment}" /> </h:form> <p:socket onMessage="handleMessage" channel="/counter" /> <script type="text/javascript"> function handleMessage(data) { $('.display').html(data); } </script> </h:body> </html>
This is PushBean.java
package Bean; import javax.faces.bean.ManagedBean; import javax.faces.bean.SessionScoped; import org.primefaces.push.PushContext; import org.primefaces.push.PushContextFactory; @ManagedBean @SessionScoped public class PushBean implements java.io.Serializable { private static final long serialVersionUID = 1L; public PushBean() { } private int count; public int getCount() { return count; } public void setCount(int count) { this.count = count; } public synchronized void increment() { count++; PushContext pushContext = PushContextFactory.getDefault().getPushContext(); pushContext.push("/counter", String.valueOf(count)); } }
From this link it says:
Many causes of this "ResourceConfig" error message. A few solutions that I know:
- com.sun.jersey.config.property.packages does not exist in your web.xml.
- com.sun.jersey.config.property.packages has included a resource that does not include knitwear services. In the above case, "com.mkyong.rest" does not contain any knitted services.
So, I think that maybe bean.PushBean in web.xml is wrong? ?
However, I do not know how to change it (if bean.PushBean is a problem). From the eclipse project explorer, the PushBean.java path is Java resources → src → Bean → PushBean.java
Please help me find a solution. Thanks in advance.
