Can i use api 3.0 servlet and berth 8?

Question

I want to use 3.0 servlet-api with Jetty 8. Currently 2.4 servlet-api is defined in my web.xml. And in the webdefault.xml 2.5 file servlet-api is defined. Someone else asked this so they would do something wrong very well. What version of servlet api am i using? 2.4 or 2.5? I already have 3.0 in my classpath. What do I need to change in web.xml and / or webdefault.xml to make it work?

Thanks in advance.

Usually you do not provide the Servlet API yourself. This is typically provided by the target servlet container itself. Examples of Servlet 3.0 compatible containers: Tomcat 7.x , Glassfish 3.x , JBoss AS 6.x / 7.x and, yes, Jetty 8.x.

You just need to declare the root element of the <web-app> web.xml to match the highest version supported by the target container.

 <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" 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_3_0.xsd" version="3.0"> </web-app>
