REST giving 404

Question

I have written a REST webservice using jersey in a project where it works fine(eclipse). Now I am trying to move that webservice into an already existing project but there its failing with 404 status. The web.xml of the project where it was working is :

<?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="3.0">
 <servlet>
    <servlet-name>Jersey REST Service</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.javatpoint.rest</param-value>
    </init-param>
    <init-param>
       <param-name>jersey.config.server.provider.classnames</param-name>
       <param-value>org.glassfish.jersey.filter.LoggingFilter;org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>Jersey REST Service</servlet-name>
    <url-pattern>/rest/*</url-pattern>
 </servlet-mapping>
</web-app>

Now with this configuration and "jerseyhelloworldtest" being name of my .war file, I am able to access the webservice using URL http://localhost:8080/jerseyhelloworldtest/rest/files/name But when I move the same webservice to another project and change the jerseyhelloworldtest with that project's .war file name its not working there. The web.xml of the project is :

<?xml version="1.0" encoding="UTF-8"?>

Now here I am trying to access the same webservice by using URL http://localhost:8080/Softwarepartwebservice/rest/files/name but its giving 404. Need help with this.

Answer 1

Sorry it was a very silly mistake made by me which I never noticed. On changing the project I had to update the package entry in

  <init-param>
    <param-name>jersey.config.server.provider.packages</param-name>
    <param-value>com.javatpoint.rest</param-value>
 </init-param>

to my new package where service class was put. com.javatpoint.rest was the package from old project which I changed to new one. Changing that made it work. Writing here in case this might help someone facing the same issue.
