Jersey : How to prevent Conflicting URI templates with other web services in the same web app

I am trying to introduce Jersey web service into a web application that has other web services (such as Apache CXF in it) in it. So I added Jersey servlet to my web.xml..
<servlet>
<servlet-name>jersey-servlet</servlet-name>
<servlet-class>
com.sun.jersey.spi.spring.container.servlet.SpringServlet
</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.freedomoss.crowdcontrol.api</param-value>
</init-param>
<init-param>
<param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jersey-servlet</servlet-name>
<url-pattern>/service/*</url-pattern>
</servlet-mapping>
During intiliazation this servlet gives the following error about conflicting URL templates...
INFO: Registering Spring bean, restApiService, of type com.mycompany.ws.RestApiService as a root resource class
Mar 12, 2015 11:07:42 PM com.sun.jersey.spi.spring.container.SpringComponentProviderFactory registerSpringBeans
SEVERE: The following errors and warnings have been detected with resource and/or provider classes:
SEVERE: Conflicting URI templates. The URI template / for root resource class com.mycompany.ws.RestApiService and the URI template / transform to the same regular expression (/.*)?
When I look in the code of this RestApiService, I see..
#Path("/")
#Service
public class RestApiService extends AbstractRestService {
Since this other web service is being used elsewhere in the application I cannot change the value of 'Path' although doing so does solve my problem
What else can I do? Can I somehow tell Jersey Servlet not to register this other web service "as a root resource class"?
My goal is to make Jersey work along with this other web service and not change the latter in any way.

Jersey Servlet not found after switching to Spring

I have a simple RESTful Java web service...
#Service
#Path("/getAccountBalance")
public class GetAccountBalanceService {
#Autowired
private ILicenseService licenseService;
#GET
#Path("/{param}")
public Response provideService(#PathParam("param") String licenseUUID) {
License license = this.licenseService.getByUUID(licenseUUID);
String output = "Balance on the account : " + license.getBalanceValue();
return Response.status(200).entity(output).build();
}
At first I was getting an error where the bean licenseService was null even though I am autowiring it. So based on advice from another post I swtiched to use the Spring servlet for jersey, thus in my web-xml I changed from com.sun.jersey.spi.container.servlet.ServletContainer to...
<servlet>
<servlet-name>jersey-servlet</servlet-name>
<servlet-class>
com.sun.jersey.spi.spring.container.servlet.SpringServlet
</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.freedomoss.crowdcontrol.api</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<servlet-mapping>
<servlet-name>jersey-serlvet</servlet-name>
<url-pattern>/service/*</url-pattern>
</servlet-mapping>
But now when I start Tomcat I am getting the error..
Dec 19, 2014 12:13:13 AM org.apache.catalina.startup.ContextConfig applicationWebConfig
SEVERE: Parse error in application web.xml file at jndi:/localhost/mturk-web/WEB-INF/web.xml
java.lang.IllegalArgumentException: Servlet mapping specifies an unknown servlet name jersey-serlvet
Why is this happening? As you can see there is a servlet defined with that name in web-xml. If there was something wrong with loading that servlet why don't the logs tell that story?
Thanks.

I think your version of Jersey is too old. Please check your dependecies.
Jersey 2.0 supports JAX-RS 2.0.
Here is link for new Jersey.

Jersey Tutorials from Basics

I am using Jersey 1.8 and the tutorials that I am referring are quiet old. Nothing works. I am referring to the tutorial given here
And get a class not found exception. as per the tutorial I made my Java Class as well as configured my web.xml. It shows me an exception and I am not getting a way to fix this. I would like to have a complete up to date tutorial for Jersey implementation. And if something is better than Jersey for REST implementation please suggest. I have rescently started with REST based web services and would appreciate if you can suggest me where to start from(I am only interested in REST). Below is the code that I wrote and compiled using eclipse.
Hello.java
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
#Path("/hello")
public class Hello {
//This method prints the Plain Text
#GET
#Produces(MediaType.TEXT_PLAIN)
public String sayPlainTextHello()
{
return "Hello Jersey";
}
//This is the XML request output
#GET
#Produces(MediaType.TEXT_XML)
public String sayXMLHello()
{
return "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";
}
//This result is produced if HTML is requested
#GET
#Produces(MediaType.TEXT_HTML)
public String sayHTMLHello()
{
return "<html> " + "<title>" + "Hello Jersey" + "</title>"
+ "<body><h1>" + "Hello Jersey" + "</body></h1>" + "</html> ";
}
}

You're not exactly following the tutorial. You changed bits here and there without actually understanding what they represents. In this particular case, according to the exception,
com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not contain any root resource classes.
the following init param is wrong
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>RESTFullApp</param-value>
</init-param>
It should refer to the package containing the services. Put your service in a package and specify that in the init param value. Jersey or not, using the default package is always a bad practice.
As to the tutorials, why don't you just read Jersey's own documentation? Jersey Wiki and Jersey User Guide.

Try the Jersey User Guide. It will pretty much always have the most up-to-date tutorial. As for the error, your web.xml declares that your resources classes will be in a package called "RESTFullApp". 1) That's a peculiar package name, and 2) I don't see a package declaration on your class.
Edit: For a working example, you check out my sample project on github. If you have git and maven, you can clone it and run it with
git clone git://github.com/zzantozz/testbed.git tmp
cd tmp
mvn jetty:run -pl basic-jersey
Then visit http://localhost:8080/basic-jersey/rest/test

Deploying Jersey-enabled servlet to Tomcat: Exceptions

Here is what I'm trying to do: we are switching over to using JAXB and Jersey for all our REST services and XML/JSON serialization needs.
So far, I have been able to get a simple test working where some beans are annotated, some test objects created and these are perfectly serialized to either XML or JSON and return to the client upon request. I mostly wrote this based on some of the examples around the Internet, where the an HTTPServer is created and started in the main method.
I am now trying to put this same example into a WAR file and deploy it to my local Tomcat server so I can test it in a more production-like environment. Seeing as I was not able to get it to work on Tomcat 5.5.27 following the instructions here I went ahead and upgraded to Tomcat 6.0. Same instructions, same outcome, a huge InvocationTargetException.
What exactly am I missing guys?

You have probably a conflict somewhere, check your jar files and see if there are no duplicate classes. Use Tattletale to locate the problem
