Have a problem migrating Jersey Webservice from JBOSS 5.1.0 to JBOSS 7.1.1

[Pongsakorn Semsuwan]

Hi,

I have to migrate my REST webservice built by Jersey from JBOSS 5.1.0 to JBOSS 7.1.1

The webservice works fine on 5.1 but when I try deploying it on 7.1.1 I run into some problem as follows

1. There's this error about JAX-RS

org.jboss.as.server.deployment.DeploymentUnitProcessingException: Only one JAX-RS Application Class allowed

This is because jboss 7 comes with RESTEASY and don't want me to use Jersey. I found solution commenting out two lines in standalone.xml and it's working fine.

2. Then I got linkage error

java.lang.LinkageError: Failed to link com/sun/jersey/api/json/JSONWithPadding 

Google said that I have to bundle jackson-all-1.8.5.jar to my lib and now this error disappear.

3. At this point, the webservice is deployable but when I try to call it, it spits this error

com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not contain any root resource classes.
	com.sun.jersey.server.impl.application.RootResourceUriRules.<init>(RootResourceUriRules.java:99)
	com.sun.jersey.server.impl.application.WebApplicationImpl._initiate(WebApplicationImpl.java:1300)

	org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:930)
	java.lang.Thread.run(Thread.java:619)

This is normally the case that either my web.xml does not state com.sun.jersey.config.property.packages (which it does) or the package I state does not have Jersey compatible class (which it has, because it works on JBOSS 5.1)

I cannot find the solution for this. Please help. Thank you in advance.

This is how my web.xml looks like

<web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

   	@Path("/testWebService/{param}")  
    public String testWebService(@PathParam("param") String param )
    { 	
        return "call successful [" + param + "]";
    }
    
    }
