Create a web service with Tomcat 5.5.30 and Jersey - eclipse

Question

I am strugging to make a Hello World Jersey web service on my Tomcat 5.5.30. I am using Eclipse Galileo.
I am NOT using Maven.
created a Dynamic Web Module in version 2.4
created a new Package com.company.webservice in Java Resources: src folder of the Eclipse project
added the following libraries to the project, from jaxrs-ri-2.19:
javax.ws.rs-api-2.0.1.jar
jersey-client.jar
jersey-common.jar
jersey-container-servlet.jar
jersey-container-servlet-core.jar
jersey-media-jaxb.jar
jersey-server.jar
aopalliance-repackaged-2.4.0-b25.jar
asm-debug-all-5.0.3.jar
hk2-api-2.4.0-b25.jar
hk2-locator-2.4.0-b25.jar
hk2-utils-2.4.0-b25.jar
javassist-3.18.1-GA.jar
javax.annotation-api-1.2.jar
javax.inject-2.4.0-b25.jar
javax.servlet-api-3.0.1.jar
jaxb-api-2.2.7.jar
jersey-guava-2.19.jar
org.osgi.core-4.2.0.jar
osgi-resource-locator-1.0.1.jar
persistence-api-1.0.jar
validation-api-1.1.0.Final.jar
Here is my web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="2.4">
<display-name>WS_Server</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>HelloService</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.company.webservice</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>HelloService</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>
I then added the following HelloService.java in the package created:
package com.company.webservice;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;
#Path("/hello")
public class HelloService {
#GET
#Path("/{param}")
public Response getMsg(#PathParam("param")
String msg) {
String output = "Jersey answers : " + msg;
return Response.status(200).entity(output).build();
}
}
But when I start the Tomcat Server I get the following error:
4 août 2015 09:31:29 org.apache.catalina.core.ApplicationContext log
INFO: La servlet HelloService est marqué comme indisponible

UPDATE
If I deploy the jars in the apache-tomcat-5.5.30\webapps\ServeurWS\WEB-INF\lib folder (thank you peeskillet for this), I have another error, looks like a version error:

Answer 1

So what I had to do was to remove all previous libraries and to use only these libraries:
jersey-bundle-1.1.5.1.jar
asm-3.1.jar
jsr311-api-1.1.1.jar
Change the web.xml into:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="2.4">
<display-name>ServeurWS2</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>HelloService</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.company.webservice</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>HelloService</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>
and to copy the libraries in the WEB-INF\lib folder of the application in the webapps folder of tomcat server.
