Hi, I'm learning REST, and when I tried to cerate a simple hello world application on JDeveloper 11.1.1.3 and WebLogic 10.3.3, the code compiled properly, but the deployment failed.
The jar files I used are:
asm-3.1.jar
j ackson-core-asl-1.5.5.jar
jackson-jaxrs-1.5.5.jar
jackson-mapper-asl-1.5.5.jar
jackson-xc-1.5.5.jar
jersey-client-1.5.jar
jersey-core-1.5.jar
jersey-json-1.5.jar
jersey-server-1.5.jar
jettison-1.1.jar
jsr311-api-1.1.1.jar
The code, deployment descriptor and erros are as follows:
HelloWorld.java
package com.rest;

import javax.ws.rs.Path;
import javax.ws.rs.GET;
import javax.ws.rs.Produces;

@Path("/hello")
public class HelloWorld {

@GET
@Produces("plain/text")
public String hello() {
return "Hello World";
}
}

web.xml
<?xml version = '1.0' encoding = 'windows-1252'?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5" xmlns="http://java.sun.com/xml/ns/javaee">
<servlet>
<servlet-name>jersey</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.rest</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jersey</servlet-name>
<url-pattern>/jersey/*</url-pattern>
</servlet-mapping>
</web-app>
The section of web.xml in italics was written by me. The rest was autogenerated by JDeveloper.
Now,the error during deployment was as follows:

I'd be most grateful if anybody could point out what I'm doing wrong.
Thank you
