CXF Webservice Using Embedded Jetty

By admin | June 16, 2014 | Updated : April 29, 2016 cxf, jetty, 2 Comments

In this tutorial we are going to test a webservice using embedded Jetty instance and JUnit. Here we are testing a simple REST service implemented by CXF framework, It works as a standalone application.

CXF Webservice Using embedded Jetty

Jetty provides a Web server and javax.servlet container, plus support for SPDY, WebSocket, OSGi, JMX, JNDI, JAAS and many other integration. These components are open source and available for commercial use and distribution

Reference -> http://www.eclipse.org/jetty/

Note

You can also check this same application with Embedded Tomcat instance Apache CXF And Embedded Tomcat

Required Libraries

You need to download

hamcrest-core-1.3.jar (Required for JUnit)
jetty-all-8.1.2.v20120308.jar
servlet-api-3.1.jar

CXF Webservice Using embedded Jetty

Testing REST service with an embedded Jetty instance

Here we are using JUnit and embedded Jetty for testing different rest methods (getName-> GET & changeName-> POST). We are attaching CXFRestfulTutorial.war programmatically and this war contains all the rest methods(getName & changeName) we are going to test.

Hi,

I am getting an exception like
org.eclipse.jetty.http.HttpBuffers cannot be resolved. It is indirectly referenced from required .class files, any idea?

admin 2014-06-19 11:05:32.0

@Rats,

This issue is related to HttpBuffers class, which internally used by your program.

You can select one from following two approaches

1) You need to import the jetty-http-7xxxx.jar to your project's class path, It already have HttpBuffers class
2) You can download jetty-all.jar, which contains all the required class in a single package as mentioned in my example.
