web.xml

<?xml version="1.0"  encoding="iso-8859-1"?> <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">     <display-name>test</display-name>     <servlet>         <servlet-name>jersey rest service</servlet-name>         <servlet-class>org.glassfish.jersey.servlet.servletcontainer</servlet-class>         <init-param>             <param-name>javax.ws.rs.application</param-name>             <param-value>com.foo.bar</param-value>         </init-param>         <!--<load-on-startup>1</load-on-startup>-->     </servlet>      <servlet-mapping>         <servlet-name>jersey rest service</servlet-name>         <url-pattern>/*</url-pattern>     </servlet-mapping>  </web-app> 

resourceconfiguration.java

package com.foo.bar;  import org.glassfish.jersey.server.resourceconfig;  public class resourceconfiguration extends resourceconfig {     public resourceconfiguration() {         register(entrypoint.class);     }  } 

and service class

package com.foo.bar;  import javax.ws.rs.get; import javax.ws.rs.path; import javax.ws.rs.produces; import javax.ws.rs.core.mediatype;  public class entrypoint {     @get     @path("/test")     @produces(mediatype.text_plain)     public string test() {         return "it works";     }      @get     @path("/")     @produces(mediatype.text_html)     public string test2() {         return "it works";     }  } 

nothing fancy right feel should work out of box. jetty server starts said jetty 404 pages @ every url permutation try.

thanks in advance , input.

few changes need done make work. please follow below steps.

step 1: change web.xml below pojo mapping , resourse configuration class instead of package name.

<servlet>         <servlet-name>jersey rest service</servlet-name>         <servlet-class>org.glassfish.jersey.servlet.servletcontainer</servlet-class>         <init-param>             <param-name>javax.ws.rs.application</param-name>             <param-value>bar.com.ravi.resourceconfiguration</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 rest service</servlet-name>         <url-pattern>/*</url-pattern>     </servlet-mapping> 

step 2: change resourceconfiguration class below package information.

public class resourceconfiguration extends resourceconfig {     public resourceconfiguration() {         packages("bar.com.ravi");         register(entrypoint.class);     }  } 

step 3: change entrypoint class class level @path annotation.

  import javax.ws.rs.get;     import javax.ws.rs.path;     import javax.ws.rs.produces;     import javax.ws.rs.core.mediatype;      @path("/hi")     public class entrypoint {         @get         @path("/test")         @produces(mediatype.text_plain)         public string test() {             return "it works";         }          @get         @path("/")         @produces(mediatype.text_html)         public string test2() {             return "it works";         }      } 

step 4: change pom.xml in build tag below.

<build>     <finalname>bar</finalname>         <plugins>             <plugin>                 <groupid>org.eclipse.jetty</groupid>                 <artifactid>jetty-maven-plugin</artifactid>                 <version>9.2.11.v20150529</version>                 <configuration>                     <scanintervalseconds>10</scanintervalseconds>                     <webapp>                         <contextpath>/bar</contextpath>                     </webapp>                     <httpconnector>                         <port>8888</port>                     </httpconnector>                 </configuration>             </plugin>         </plugins>     </build> 

step 5: run below command command promt.

mvn jetty:run 

step 6: hit browser below url

http://localhost:8888/bar/hi/test
