Java Jersey cannot find resoruce

Question

I have created a jersey web service and deployed it on a tomcat application server. I have the war file deployed in tomcat, but still when I try to access the application a got an error that the requested data could not be found(The standard tomcat 404 error). This is my web.xml file.

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

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> Jersey index.html

<servlet>
    <servlet-name>Jersey REST Service</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>sample.jsonStrip.resources</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>RestServlet</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

This is my pom.xml

Both of the xml files are in located in Jersey root folder. I have seen some cases when wab.xml is situated in WebContent/WEB-INF/web.xml? Where should I place it?

Thanks!

Answer 1

The <servlet-name> in the web.xml need to match in both locations

In the <servlet-mapping>, the <servlet-name> tells the container what servlet this mapping should apply to, by looking for a <servlet> with the same <servlet-name>. Right now your Jersey servlet has no URL mapping, so it won't handle any requests.

I have seen some cases when wab.xml is situated in WebContent/WEB-INF/web.xml? Where should I place it?

There. I haven't used eclipse in a while, but I'm pretty sure the WebContent folder isn't a "real" folder. It is only an IDE display folder. It should map in the real directory structure to src/main/webapp in a Maven application. That's where the web.xml should be src/main/webapp/WEB-INF
