Jetty is a pure Java-based HTTP server and Java Servlet container.
Jetty provides support for SPDY, Web Sockets, OSGi, JMX, JNDI,
JASPI, AJP and many other integrations.
More details about jetty please click following links.
This blog instruction will help us to create a sample webservice using
cxf using embedded jetty (jetty://).
Developing sample restful webservice please go through following link.
The link will help you to create sample restful
webservice in details.
In this section we will only configure jaxrs server to use cxf embabed jetty.
Post production testing procedure will be as same as discussed is previous blog.
Please click on jaxws or jaxrs browse testing section for more details procedures.
Embedded Jetty
CXF documents
HTTP jaxws setup with CXF using embedded Jetty
- Create a dynamic web project.
- Create a folder wsdl under WEB-INF.
- Create a file Sample.wsdl under WEB-INF\wsdl.
- Add following wsdl snippet in WEB-INF\wsdl\Sample.wsdl and save the file.
- Generate java classes and service interfrace using eclipse wsdl2java.
- Modify GreetingsImpl.java add following code snippet.
- Modify generated web.xml WEB-INF/web.xml add following xml snippet.
- Create a xml file name cxf-jetty-beans.xml under WEB-INF/conf
- Modify generated cxf-beans.xml WEB-INF/conf/cxf-beans.xml add following xml snippet.
- Export and package this as war.Destination path %JBOSS_HOME%\server\default
- Open command prompt and go to directory %JBOSS_HOME\bin
- Execute run.bat -c default -b 0.0.0.0 Deployement will be sucessfull according to above instructions. following log message will apear in jboss console log.

HTTP jaxrs setup with CXF using embedded Jetty
Developing sample restful webservice please go through following link.
The link will help you to create sample restful
webservice in details.
In this section we will only configure jaxrs server to use cxf embabed jetty.
- Create a xml file name cxf-jetty-beans.xml under WEB-INF/conf
- Modify jaxrs-beans.xml under WEB-INF/conf and mention the jetty host port in jaxrs server section
